3V coin-type lithium polymer battery with pressure contact terminals and ideally suited for use in all kinds of products where the trend is to achieve increasing miniaturization. Since the manganese dioxide that is chemically very stable is used for the plus terminal as an active material, if preservation conditions are proper, 90% of capacity remains even after ten years of storage. It employs organic electrolytes with minimum creeping, so they are vastly superior regarding leakage resistance under environmental changes.
