Abstract

A matted particulate electrode located between the current collector and a porous separator of a rechargeable lithium battery is described, which contains electro-active particles intermixed with pliable, solid, lithium ion conducting, polymer electrolyte filaments having adhesive surfaces. The electro-active particles and the optionally added electro-conductive carbon particles adhere to the tacky surface of the adhesively interlinking polymer electrolyte filaments. The matted particulate electrode is impregnated with an organic solution containing another lithium compound. In a second embodiment the porous separator is coated on at least one of its faces, with polymer electrolyte having an adhesive surface and made of the same polymer as the electrolyte filaments. The polymer electrolyte filaments in the matted layer may adhere to the coated surface of the separator. In addition the polymer coating is partially filling the pores of the porous electrolyte, but leaving sufficient space in the pores for the organic solution to penetrate the separator of the lithium battery.
