  • Publication number: 20020136957
    Abstract: Lithium-ion electrochemical cells include an anode, a cathode and a separator between the anode and cathode, wherein at least one of the anode, cathode and separator includes a polysiloxane coating thereon. Most preferably, the polysiloxane coating is the polymerized reaction product of dimethyl siloxane and tetra(trimethylsiloxy) silane), and is present on the surface in an amount between about 0.05 to about 0.17 mg/cm2. After being coated with the polysiloxane adhesive, the electrodes and separator can easily be attached one to another at ambient temperature by application of pressure using a hand roller or with a laminator, and then subsequently formed into a spiral or stacked structure for placement in a battery cell case.

  • Publication number: 20020136958
    Abstract: Ionic gel polymer electrolytes for rechargeable polymer batteries. In preferred forms, a gel polymer precursor electrolyte is formed by dissolving a gelling agent into organic liquid electrolytes, and then gelling the precursor in situ at elevated temperature after pouring it into a battery case that contains a cathode, an anode and a separator. The gel polymer electrolytes exhibit excellent ionic conductivity of up to about 10−2 S/cm and voltage stability for lithium rechargeable batteries.
