Definitions
- the present invention relates to fabrication methods for polymer batteries using liquid polymer electrolytes. More particularly, the present invention relates to a method to improve the performance of liquid electrolyte alkali metal polymer batteries (especially, lithium metal and lithium ion) including, rate, capacity, and cycle life.
- alkali metal polymer batteries especially, lithium metal and lithium ion
- rate, capacity, and cycle life As used herein, "lithium battery” or “lithium ion battery” shall be defined as including batteries made with any alkali metals or alkaline earth metals whether or not a metal electrode is used.
- Polymer lithium batteries offer substantial advantages over lithium batteries with currently-known liquid electrolytes. Among these advantages are enhanced safety, long cycle life, high energy density, and flexibility. Polymer lithium batteries also hold great promise to be manufactured with ease, since thin film processes in the polymer industry can be used or adapted to the production of secondary lithium ion batteries.

- One of the key issues in commercializing secondary lithium ion polymer batteries is the ionic conductivity of polymer electrolyte, which is essential for high rate operation of the lithium battery.
- Some polymeric electrolyte solutions can be applied to the electrolyte filling process in lithium ion secondary battery manufacture in the same way as the other electrolytes such as carbonate-based solutions.
- Lithium ion secondary batteries with the polymer as a conducting medium can be fabricated by injecting the polymeric electrolyte solution into a spiral jelly roll type cell or a stacked cell. It can also be coated onto the surface of electrodes and assembled with a porous separator to fabricate single or multi- stacked cells that are packaged within a plastic or plastic-coated aluminum type pouch. These techniques are well-known in the art; however, they are not suitable for viscous ipolymers such as siloxanes and phosphorous hetero-polymers because of their high viscosity.
- liquid polymer electrolytes are more thermally stable and less volatile than low molecular weight chemicals such as carbonates. Therefore, the present inventors have investigated the wetting and penetration mechanism of viscous liquid polymer electrolytes and have developed a new electrode manufacturing process that incorporates the liquid polymer during the fabrication of the electrodes.
- the liquid polymer electrolytes used in the composite electrodes have beneficial characteristics such as high conductivity and i stability at higher temperatures than are used for drying the solvent used to mix the binder.
- the present inventors have developed liquid polymer electrolytes that do not evaporate at temperatures up to 150°C, offer high ionic conductivity around room temperature, and have a wide electrochemical stability window.
- the high viscosity of these new polymer electrolytes inhibits effective penetration and wetting of electrode materials. Therefore, a need was seen to develop a new method to effectively manufacture batteries with viscous polymer electrolytes such as polysiloxane electrolytes.
- the aim of this invention was to develop an engineering and manufacturing process that overcomes the problem of the viscous liquid polymers and permits the polymers not only to wet, but also to effectively penetrate the bulk of the electrode.
- the present invention incorporates the polymer electrolyte mixed with the salt and conductive agent (e.g., acetylene black, natural graphite, artificial graphite, graphite whiskers, graphite fibers, metal whisker, metal fibers, etc.) in a slurry that contains the active material.
- the slurry may also contain a binder and/or a solvent (e.g., N-methylpyrrolidone (NMP), acetonitrile, or water) to adjust the casting viscosity.
- NMP N-methylpyrrolidone
- the slurry is then cast on or around the current collector and dried at temperatures around 120°C. This forms an electrode with much lower porosity than that in conventional lithium ion batteries.
- the pore volume is equal to that of the volume of the solvent such as NMP used in dissolving the binder.
- Protective additives may also be incorporated. These additives form a passivation film (solid-electrolyte interface (SEI)), on the negative electrode and may suppress gas evolution. Such additives may be incorporated into the electrolyte. Accordingly, the invention is a new fabrication method in which the electrode contains at least some of the polymer electrolyte when it is formed. These electrodes are highly suitable for electrochemical devices such as lithium batteries and capacitors. Additional penetration and wetting of the electrodes may be carried out after formation by the use of vacuum impregnation.
- An object of the present invention is to provide a composite electrode structure, with improved capacity, cycling, and manufacturability.
- a further object of the present invention is to provide a method of manufacture which is easily applied to the lithium ion electrode technology.
- Yet a further object of the present invention is to provide an improved fabrication method for electrodes, especially for use in consumer products, electric and hybrid-electric vehicles, submarines, medical and satellite applications.
- Fig. 1 is a schematic of the composite electrode made according to the present invention.
- Fig. 2 is a flow chart of the fabrication process for an electrode made according to the present invention.
- Fig. 3 shows charge (Li de-intercalation) curves for three composite negative electrodes made according to the present invention.
- Fig. 4 shows charge (Li de-intercalation) curves of composite electrodes made according to the present invention.
- Fig. 5 is a cycling capacity graph for several composite electrodes made according to the present invention.
- Table 1 summarizes experiments carried out with the purpose of cycling the electrode when using different methods of incorporating the polymer in the electrodes. As can be seen, all the processes of electrolyte filling (after casting of the electrode) were unsuccessful due to the high viscosity of the electrolyte and its inability to penetrate the electrode material.
- Table 1 Capacity of carbon materials and processes used for polymer electrolyte filling carbon-lithium metal cells.
- the present inventors developed a process for mixing the polymer electrolyte directly with the active materials and binder during the process of slurry making. This process allows for an intimate mix of the polymer with the active material providing lithium ion conductive network needed for cycling the electrodes.
- the liquid type polymeric electrolytes should be composed of nonvolatile compounds. In the case of lithium ion batteries, the amount of polymer during the mixing process should be equal to or greater than the volume of electrode.
- the electrode should contain about 20% to 60% pores.
- Fig. 1 shows a schematic of composite electrode 100, which contains a positive or negative active material 102, conducting agent 104 (carbon black, graphite powder, and mixtures thereof), polymer binder (such as poly(vinylidene fluoride) (PVDF), styrene- butadiene rubber (SBR), acrylate binder, other rubber binders, and mixtures thereof) 108, current collector 112, and the liquid type polymeric electrolyte 116.
- the polymer electrolyte 116 is an integral part of the electrode.
- the density of composite electrode is preferably about 1.2 - 3.0 g/cc, but may be as high as about 8.0 g/cc.
- the proposed composite electrode structure and its processing method yield high charge/discharge characteristics.
- a follow-on vacuum impregnation process after forming the composite electrode (containing polymer electrolyte) was effective in further improving the charge/discharge characteristics.
- the polymeric electrolyte 116 is preferably a polysiloxane liquid. Its structure may take a variety of forms, including, but not limited to, any of the following, with or without propylene spacers between the Si atom of main chains and any PEO side chain.
- Ri, R 2 , R 3 , R 7 , R 8 , R 9 and R ⁇ 0 are alkyl groups, preferably chosen from methyl, ethyl, propyl, and butyl; at least one of -R*. and -R 5 is represented by General Formula II; R 6 is an alkyl group preferably chosen from methyl, ethyl, propyl and butyl or represented by General Formula III; n is equal to 3 to 200, m is equal to 0 to 200;

- Fig. 2 is a flow chart showing the steps of the fabrication process of composite electrodes and the cell.
- the process is similar to that traditionally used in lithium ion technology except for adding liquid polymer electrolyte to the slurry before the coating process and formation of electrodes. Therefore, this process is easy to implement for the mass production of electrodes.
- active material 200 e.g., active material 200, conducting agents 204 (e.g., graphite), and polymeric electrolyte 208 (e.g., poly(siloxane-g--ethylene oxide)) are mixed 212 with a binder solution 216 (e.g., PVDF, styrene butadiene rubber (SBR), acrylate binder, acrylonitrile/butadiene rubber (NBR), isoprene, and natural rubber) and one or more protective additives 218.
- a binder solution 216 e.g., PVDF, styrene butadiene rubber (SBR), acrylate binder, acrylonitrile/butadiene rubber (NBR), isoprene, and natural rubber
- SBR styrene butadiene rubber
- NBR acrylonitrile/butadiene rubber

- Protective additives 218 may include any additives that decompose at voltages higher than 0.6 V and form a passivation film (SEI film) on the negative electrode. These include, but are not limited to, vinyl ethylene carbonate (NEC), vinylene carbonate (VC), ethylene carbonate (EC), and propylene carbonate (PC). Protective additives 218 may also include additives that suppress the gas evolution at the negative electrode, such as ethylene sulfide (ES) and ethylene ethyl phosphate (EEP). See, e.g., U.S. Patent 5,753,389 to Gan et al. (assigned to Wilson Greatbatch Ltd.); Aurbach et al., J. Electrochem. Soc, 143, 3809 (1996).
- ES ethylene sulfide
- EEP ethylene ethyl phosphate
- the additives are mixed with the liquid polymeric electrolyte and may be incorporated by the electrolyte vacuum impregnation process.
- Such protective additives will suppress the evolved gas generated by the decomposition of SEI film and will improve cycling performance.
- Protective additives should preferably comprise no more than 50wt% of the total electrolyte.
- a negative composite electrode mixture of 74% by weight of the graphite powder (GDR) and 18wt% of polysiloxane/LiTFSi binder electrolyte was prepared.
- 8wt% polyvinylidene fluoride (PVDF) was added as a binder to the composite mixture.
- the PVDF was dispersed into N-methylpyrrolidone to form a slurry or paste.
- the mixture of negative composite electrode was homogeneously mixed by ball milling for 12 hrs.
- the slurry was coated onto one face of a copper foil strip having a thickness of 20 ⁇ m as a negative electrode current collector, was dried at 80°C in vacuum overnight, and was subjected to the roll press to form a strip negative electrode having a thickness of 65 ⁇ m.
- a graphite electrode was punched out to form a negative electrode with 15 mm diameter, and then electrolyte was impregnated into the electrode in a vacuum over night.
- Fig. 3 shows the effect of vacuum impregnation of siloxane polymer and electrode density on the charge/discharge characteristics. It may be seen that it is most effective to impregnate the electrodes with the liquid siloxane polymer electrolyte under a vacuum.
- Trace 300 represents the discharge cycle curve for a cell made with vacuum-impregnated electrodes with a density of 1.3 g/cc. This sample exhibited a capacity of about 300 mAh/g.
- Trace 304 shows the discharge cycle curve for a cell having vacuum-impregnated electrodes having 1.8 g/cc density. It had approximately 240 mAh/g capacity.
- Trace 308 is the discharge cycle for a cell with 1.8 g/cc density electrodes that were not vacuum-impregnated. This cell exhibited a capacity of only about 180 mAh/g, significantly less than either of the vacuum-impregnated cells tested. Electrodes were prepared by 74% GDR graphite powder, 8% PVDF binder with 18% 1-M LiTFSi/siloxane polymer electrolyte in NMP organic solvent. The mixture was coated onto copper foil, and dried under a vacuum. The electrodes were then tested in a 2016 coin cell. Lithium metal was used for the counter electrode with 1-M LiTFSi/siloxane polymer electrolyte. All the cells were tested at the C/20 rate.
- a second solvent may be added as a protective additive to the liquid polymeric electrolyte, in order to improve the wettability of negative electrode, to form the SEI film on the graphite surface, and to suppress further decomposition of liquid siloxane polymer.
- preferred additives are EC, PC, and NEC.
- a coin-shaped test cell having a diameter of 20 mm and a thickness of 1.6 mm was prepared. The cell was made up of a counter electrode/Li metal; separator/porous film formed of polypropylene; electrolyte/solution obtained by dissolving LiTFSi in a liquid polysiloxane polymer; MCMB graphite composite electrode/ current collector/copper foil. A separator was used as a microporous polypropylene film having a thickness of 25 ⁇ m.
- Fig. 4 shows the capacity characteristics of Li metal/MCMB graphite composite electrode cell comprising polysiloxane liquid polymer/ lithium bis(oxalato) borate (“LiBoB”) electrolyte containing 3% organic additive.
- the composition of MCMB composite was exactly same as that of above-mentioned GDR composite electrodes. Additional electrolyte was filled in by vacuum impregnation.
- Curve 320 shows the performance with no protective additives. Cells made with NEC, PC, and EC are shown by curves 324, 328 and 332 respectively. It may be seen that the addition of protective additives increased capacity versus the cell with no additives from just above 200 mAh/g to a range of 240 to 260 mAh/g, representing a minimum of 20% increase in capacity.
- Fig. 5 presents the cycling performance of the same type cells as in Figure 3.
- the cycling performance of the cell made with no additional protective solvents is shown by curve 360.
- the greatly improved performance by the addition of VEC, PC, and EC is shown by curves 364, 368, and 372, respectively.
- the cell with no additives 360 showed less than 150 mAh/g capacity after 10 cycles, while the cells with protective additive ranged from 200 to 240 mAh/g after 10 cycles.
- the organic additives of the present invention are reduced to form an SEI film which deposits on the graphite anode surface.
- This surface SEI film is electrochemically more stable and ionically more conductive than the SEI film formed in the absence of the organic additives.
- the surface SEI film so formed is believed responsible for improved cell performance.
