Filed: 1985-12-27
Abstract: PURPOSE:To provide a battery having good electrolyte leakage resistance by using a sealant comprising isobutylene family polymer containing ethylene/polar monomer copolymer. CONSTITUTION:A gap 5 in a battery sealing part is sealed with a sealant 4 made of a polymer mainly comprising isobutylene having a mean molecular weight of 700-10,000 containing 0.5-30wt.% ethylene/polar monomer obtained by copolymrizing 1-30wt.% polar monomer.

Vinyl acetate and ethyl acrylate are preferable as the polar monomer. The copolymer having mean molecular weight less than 700 has low viscosity and its sealing ability is insufficient. The polymer having mean molecular weight exceeding 10,000 has too high viscosity and it makes coating difficult.
