ABSTRACT:
Latex coated electrodes comprising a foraminous, electrically conductive substrate which supports a paste comprising a mixture of (a) finely divided, particulate, rechargeable, active material and, (b) a fibrous interconnecting network of an unsintered, uncoalesced, hydrophobic linear fluorocarbon polymer, wherein said active material is dispersed throughout and bound in said fibrous network and being accessible to said electrolyte and to gas being generated during overcharge of the cell have excellent mechanical integrity. These electrodes have a greater storage life than similar uncoated electrodes and rechargeable cells employing these electrodes have excellent electrical properties with respect to both voltage characteristics and pressure buildup.
