Description
FIELD
This disclosure generally relates to solid state secondary batteries, and, more particularly, to solid state lithium batteries with a multi-layer anode.
BACKGROUND
Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to the prior art by inclusion in this section.
Rechargeable lithium batteries are attractive energy storage devices for portable electric and electronic devices and electric and hybrid-electric vehicles because of their high specific energy compared to other electrochemical energy storage devices. A typical lithium cell contains a negative electrode, a positive electrode, and a separator located between the negative and positive electrodes. Both electrodes contain active materials that react with lithium reversibly. In some cases, the negative electrode may include lithium metal, which can be electrochemically dissolved and deposited reversibly. The separator contains an electrolyte with a lithium cation, and serves as a physical barrier between the electrodes such that none of the electrodes are electrically connected within the cell.
Typically, during charging, there is generation of electrons at the positive electrode and consumption of an equal amount of electrons at the negative electrode. During discharging, opposite reactions occur.
Conventional Li-ion cells employ a liquid separator between the positive and negative electrodes. Conventional liquid separator materials undergo deleterious side reactions with the highly reactive lithium species present in the battery. The coulombic efficiency of a conventional Li-ion cell is less than about 99 percent. This results in the amount of available lithium being reduced to less than 36 percent after fewer than 100 charge/discharge cycles. A conventional strategy for accommodating this loss of available lithium is to provide a large excess of lithium to the cell during fabrication. As much as 4 times the stoichiometric amount of lithium needed by the cell is often provided, resulting in thicker, heavier cells and increased material costs.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic diagram illustrating a battery cell, in accordance with some embodiments.
DETAILED DESCRIPTION
One or more specific embodiments will be described below. Various modifications to the described embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the described embodiments. Thus, the described embodiments are not limited to the embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein.
An embodiment of a battery cell 100 is shown in FIG. 1 . The battery cell 100 includes an anode current collector 110 (e.g., copper foil, nickel foil). In various embodiments, a surface of the anode current collector 110 may be modified to enhance the adhesion of subsequent materials, depending on the application. In some embodiments, the surface of the anode current collector 110 may be modified by an oxidation or acid treatment. In another embodiment, the surface of the anode current collector 110 may be modified by the addition of a metal foam (e.g., nickel foam). In certain embodiments, the surface of the anode current collector 110 may include a continuous or discontinuous seed layer to enhance lithium deposition (e.g., copper particles, lithium particles, lithium magnesium alloys and/or other lithium metal alloys). In some embodiments, the thickness of the anode current collector 110 may be less than about 25 micrometers, less than about 15 micrometers, less than 10 micrometers, greater than 1 micrometer, greater than 3 micrometers and/or greater than 5 micrometers. Depending on the application, the thickness of the anode current collector 110 may varies.
In the example of FIG. 1 , a first ad- layer 120 is, for example, disposed on or formed over the anode current collector 110 . The first ad- layer 120 acts as a filter to allow access to the anode current collector 110 to lithium ions while blocking access to the anode current collector 110 to electrons, and solvent molecules resulting in improved coulombic efficiency. The first ad- layer 120 includes materials that are ionically conductive (e.g., lithium ion conducting) and electrically insulating. Materials for the first ad- layer 120 include, but are not limited to, amorphous carbon coatings (e.g., carbon sheets, carbon particles (e.g., spherical micro-beads)), single or multi-layer boron nitride layers (e.g., crystalline boron nitride, polycrystalline boron nitride and/or amorphous boron nitride), single or multi-layer graphene oxide films (e.g., graphene oxide and/or reduced graphene oxide), and/or thin layers, less than about 5 nanometers, of a metal oxide, a metal nitride and/or a metal phosphide derivative (e.g., aluminum oxide (Al 2 O 3 ), lithium nitride (Li 3 N), lithium phosphide (Li 3 P), lithium phosphorous oxynitride (LiPON) and/or silicon nitride (Si3N4)) and combinations thereof. In some embodiments, the thickness of the first ad- layer 120 may be less than 1 micrometer, less than 50 nanometers, less than 20 nanometers, less than 10 nanometers, less than 5 nanometers, greater than 1 nanometer, greater than 2 nanometers and/or greater than 3 nanometers. Depending on the application, the thickness of the first ad- layer 120 may varies.
In the example of FIG. 1 , a second ad- layer 125 is, for example, disposed on or formed over the first ad- layer 120 . During the charging of the battery cell 100 , the lithium deposited on the anode current collector 110 may be deposited non-uniformly, which may result in lithium dendrite formation. Lithium dendrites if unmitigated can cause an internal short within the battery cell 100 allowing rapid discharge which may damage the battery cell 100 . The second ad- layer 125 may act as a protective and/or sealant layer over the first ad- layer 120 thereby forming a barrier to dendrite propagation through the battery cell 100 . The second ad- layer 125 includes materials which are ionically conductive to lithium ions while reducing or preventing undesired species from reaching the first ad- layer 120 and/or the anode current collector 110 . The introduction of the ad-layers permit charging of solid-state lithium batteries at considerably higher current density (e.g., 5 to 10 mA/cm2 vs. baseline of 0.2 to 1 mA/cm2). Materials for the second ad- layer 125 include, but are not limited to, a metal oxide derivative, a metal nitride derivative and/or a metal phosphide derivative (e.g., aluminum oxide (Al 2 O 3 ), lithium nitride (Li 3 N), lithium phosphide (Li 3 P), lithium phosphorous oxynitride (LiPON) and/or silicon nitride (Si3N4), a sulfide derivative, a garnet (e.g., lanthanide lithium zirconium oxide (LLZO)) and/or a conducting polymer (e.g., polyethylene oxide (PEO), polyvinylidene fluoride (PVDF), polymethylmethacrylate (PMMA), and/or polyacrylonitrile (PAN)) and combinations thereof. In some embodiments, the thickness of the second ad- layer 125 may be less than 1 micrometer, less than 50 nanometers, less than 20 nanometers, less than 10 nanometers, less than 5 nanometers, greater than 1 nanometer, greater than 2 nanometers and/or greater than 3 nanometers. In an alternate embodiment, one or more materials of the second ad- layer 125 may be added to the first ad- layer 120 to form a mixed first ad- layer 120 . In an alternate embodiment, the mixed first ad- layer 120 may be present in combination with the second ad- layer 125 . In another alternate embodiment, the mixed first ad- layer 120 may be present without the second ad- layer 125 . In the example of FIG. 1 , the region of the battery cell 100 including the anode current collector 110 , first ad- layer 120 and second ad- layer 125 is defined as the anode 128 . The introduction of the protective and/or sealant properties of the ad- layers
120 , 125 , in some embodiments, may allow the formation of the anode 128 to be performed by a metal foil extrusion process resulting in a more efficient manufacturing process.
In the example of FIG. 1 , a solid state ionically conductive separator 130 is either disposed on or formed over the second ad- layer 125 or the anode 128 to provide an ionically conductive electrically insulating medium through which lithium ions can move during the charging/discharging of the battery cell 100 . Materials for the separator 130 include, but are not limited to, ceramic electrolytes (e

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic diagram illustrating a battery cell, in accordance with some embodiments.
DETAILED DESCRIPTION
One or more specific embodiments will be described below. Various modifications to the described embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the described embodiments. Thus, the described embodiments are not limited to the embodiments shown, but are to be accorded the widest scope consistent with the principles and features disclosed herein.
An embodiment of a battery cell 100 is shown in FIG. 1 . The battery cell 100 includes an anode current collector 110 (e.g., copper foil, nickel foil). In various embodiments, a surface of the anode current collector 110 may be modified to enhance the adhesion of subsequent materials, depending on the application. In some embodiments, the surface of the anode current collector 110 may be modified by an oxidation or acid treatment. In another embodiment, the surface of the anode current collector 110 may be modified by the addition of a metal foam (e.g., nickel foam). In certain embodiments, the surface of the anode current collector 110 may include a continuous or discontinuous seed layer to enhance lithium deposition (e.g., copper particles, lithium particles, lithium magnesium alloys and/or other lithium metal alloys). In some embodiments, the thickness of the anode current collector 110 may be less than about 25 micrometers, less than about 15 micrometers, less than 10 micrometers, greater than 1 micrometer, greater than 3 micrometers and/or greater than 5 micrometers. Depending on the application, the thickness of the anode current collector 110 may varies.
In the example of FIG. 1 , a first ad- layer 120 is, for example, disposed on or formed over the anode current collector 110 . The first ad- layer 120 acts as a filter to allow access to the anode current collector 110 to lithium ions while blocking access to the anode current collector 110 to electrons, and solvent molecules resulting in improved coulombic efficiency. The first ad- layer 120 includes materials that are ionically conductive (e.g., lithium ion conducting) and electrically insulating. Materials for the first ad- layer 120 include, but are not limited to, amorphous carbon coatings (e.g., carbon sheets, carbon particles (e.g., spherical micro-beads)), single or multi-layer boron nitride layers (e.g., crystalline boron nitride, polycrystalline boron nitride and/or amorphous boron nitride), single or multi-layer graphene oxide films (e.g., graphene oxide and/or reduced graphene oxide), and/or thin layers, less than about 5 nanometers, of a metal oxide, a metal nitride and/or a metal phosphide derivative (e.g., aluminum oxide (Al 2 O 3 ), lithium nitride (Li 3 N), lithium phosphide (Li 3 P), lithium phosphorous oxynitride (LiPON) and/or silicon nitride (Si3N4)) and combinations thereof. In some embodiments, the thickness of the first ad- layer 120 may be less than 1 micrometer, less than 50 nanometers, less than 20 nanometers, less than 10 nanometers, less than 5 nanometers, greater than 1 nanometer, greater than 2 nanometers and/or greater than 3 nanometers. Depending on the application, the thickness of the first ad- layer 120 may varies.
In the example of FIG. 1 , a second ad- layer 125 is, for example, disposed on or formed over the first ad- layer 120 . During the charging of the battery cell 100 , the lithium deposited on the anode current collector 110 may be deposited non-uniformly, which may result in lithium dendrite formation. Lithium dendrites if unmitigated can cause an internal short within the battery cell 100 allowing rapid discharge which may damage the battery cell 100 . The second ad- layer 125 may act as a protective and/or sealant layer over the first ad- layer 120 thereby forming a barrier to dendrite propagation through the battery cell 100 . The second ad- layer 125 includes materials which are ionically conductive to lithium ions while reducing or preventing undesired species from reaching the first ad- layer 120 and/or the anode current collector 110 . The introduction of the ad-layers permit charging of solid-state lithium batteries at considerably higher current density (e.g., 5 to 10 mA/cm2 vs. baseline of 0.2 to 1 mA/cm2). Materials for the second ad- layer 125 include, but are not limited to, a metal oxide derivative, a metal nitride derivative and/or a metal phosphide derivative (e.g., aluminum oxide (Al 2 O 3 ), lithium nitride (Li 3 N), lithium phosphide (Li 3 P), lithium phosphorous oxynitride (LiPON) and/or silicon nitride (Si3N4), a sulfide derivative, a garnet (e.g., lanthanide lithium zirconium oxide (LLZO)) and/or a conducting polymer (e.g., polyethylene oxide (PEO), polyvinylidene fluoride (PVDF), polymethylmethacrylate (PMMA), and/or polyacrylonitrile (PAN)) and combinations thereof. In some embodiments, the thickness of the second ad- layer 125 may be less than 1 micrometer, less than 50 nanometers, less than 20 nanometers, less than 10 nanometers, less than 5 nanometers, greater than 1 nanometer, greater than 2 nanometers and/or greater than 3 nanometers. In an alternate embodiment, one or more materials of the second ad- layer 125 may be added to the first ad- layer 120 to form a mixed first ad- layer 120 . In an alternate embodiment, the mixed first ad- layer 120 may be present in combination with the second ad- layer 125 . In another alternate embodiment, the mixed first ad- layer 120 may be present without the second ad- layer 125 . In the example of FIG. 1 , the region of the battery cell 100 including the anode current collector 110 , first ad- layer 120 and second ad- layer 125 is defined as the anode 128 . The introduction of the protective and/or sealant properties of the ad- layers
120 , 125 , in some embodiments, may allow the formation of the anode 128 to be performed by a metal foil extrusion process resulting in a more efficient manufacturing process.
In the example of FIG. 1 , a solid state ionically conductive separator 130 is either disposed on or formed over the second ad- layer 125 or the anode 128 to provide an ionically conductive electrically insulating medium through which lithium ions can move during the charging/discharging of the battery cell 100 . Materials for the separator 130 include, but are not limited to, ceramic electrolytes (e.g., metal oxide derivatives, metal sulfide derivatives and/or metal phosphate derivatives), solid polymer electrolytes (e.g., polymers, co-polymers, block co-polymers (e.g., di-block co-polymers, and/or tri-block co-polymers)) and combinations thereof. In some embodiments, the polymers may be cross-linked. In some embodiments, the polymers may further include pendant groups. In some embodiments, the thickness of the separator 130 may be less than 25 micrometers, less than 20 micrometers, less than 15 micrometers, less than 10 micrometers, greater than 2 micrometers and/or greater than 4 micrometers.
The lithium species present in the battery cell 100 are highly reactive. In a conventional battery cell the liquid separator materials undergo deleterious side reactions with the highly reactive lithium species present near the anode current collector 110 resulting in reduced coulombic efficiency thus shortening battery life. In the example of FIG. 1 the ad- layers
120 , 125 act as a barrier between the separator 130 and the reactive lithium species near the anode current collector 110 .
The solid state materials of the separator 130 are less reactive to the lithium species present in the battery cell than conventional liquid separator materials. This reduced reactivity in conjunction with the isolation provided by the ad- layers
120 , 125 results in improved coulombic efficiency of the battery cell 100 . In some embodiments, the coulombic efficiency is greater than 99.9 percent. In certain embodiments the coulombic efficiency can exceed 99.99 percent resulting in over 80 percent of the lithium being available in the battery cell 100 after more than 2000 charge/discharge cycles. The high utilization of lithium in the battery cell 100 results in less lithium being needed within the battery cell 100 resulting in reduced material costs.
In some embodiments, an electrolyte salt may be added to the separator 130 to provide additional mobile ions of the charge carrier of the battery cell 100 . Any electrolyte salt that includes the ion identified as the most desirable charge carrier for the application can be used. It is especially useful to use electrolyte salts that have a large dissociation constant within the polymer electrolyte. In one embodiment, the electrolyte salt may include a working ion such as LiTSI. Other suitable working ion for the electrolyte salt may be used.
Suitable examples of electrolyte salts include alkali metal salts (e.g., lithium salts). Examples of useful lithium salts include, but are not limited to, lithium hexafluorophosphate (LiPF 6 ), lithium bis(trifluoromethanesulfonimide) (LiN(CF 3 SO 2 ) 2 ), lithium tris(trifluoromethane) sulfonyl methide, (Li(CF 3 SO 2 ) 3 C), lithium bis(perfluoroethylsulfonylimide) (LiN(SO 2 CF 2 CF 3 ) 2 ), lithium boron dioxalate (LiB(C 2 O 4 ) 2 ), lithium fluorododecaborates (Li 2 B 12 F x H 12-x ), lithium nitrate, dilithium dodecafluorododecaborate (Li 2 (B 12 F 12 )), lithium tetracyanoborate (LiB(CN) 4 ) and combinations thereof.

In some embodiments, the solid polymer electrolyte may include a block co-polymer. Further details about the block co-polymer for the solid polymer electrolyte can be found in U.S. patent application Ser. No. 14/700,260, filed Apr. 30, 2015.
In the example of FIG. 1 , a cathode 140 is either disposed on or formed over the separator 130 . The cathode 140 includes a cathode active material able to provide ionic conductivity and accommodate the accumulation of the lithium oxidation product in the cathode 140 . In some embodiments, the volume fraction of the cathode active materials of the cathode 140 may be 40 volume percent to 70 volume percent. Suitable materials for the cathode active material include, but are not limited to, sulfur or sulfur-containing materials (e.g., polyacrylonitrile-sulfur composites (PAN-S composites), lithium sulfide (Li 2 S)); vanadium oxides (e.g., vanadium pentoxide (V 2 O 5 )); metal fluorides (e.g., fluorides of titanium, vanadium, iron, cobalt, bismuth, copper and combinations thereof); lithium-insertion materials (e.g., lithium nickel manganese cobalt oxide (NMC), lithium-rich NMC, lithium nickel manganese oxide (LiNi 0.5 Mn 1.5 O 4 )); lithium transition metal oxides (e.g., lithium cobalt oxide (LiCoO 2 ), lithium manganese oxide (LiMn 2 O 4 ), (LMO), lithium nickel cobalt aluminum oxide (NCA), nickel manganese cobalt oxide derivatives (e.g., NCM), high energy nickel manganese cobalt oxides (HENCM), and combinations thereof); lithium phosphates (e.g., lithium iron phosphate (LiFePO 4 ), (LFP)), a porous conductive material (e.g., carbon black, carbon fiber, graphite, graphene and combinations thereof) and an electrolyte (e.g., the electrolyte embodied above).
