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. [0006]
  • 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.

  • 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.
