GEL-FORMING BATTERY SEPARATOR

摘要

Gel-forming battery separators and methods for constructing them. Particles are embedded into pores of a porous support to form a composite. The chemical make-up of surfaces of the particles includes a silanol group. The composite, when contacted with an effective amount of liquid electrolyte, is capable of forming a gelled matrix that includes electrolyte residing within the porous support. Batteries and methods of forming batteries featuring gel-forming separators are also disclosed. No pre-mixing of siliceous material with electrolyte is required facilitating battery construction.
