Although, batteries have been constantly changing and revolutionizing since their birth. However, the most widely used is the zinc-manganese battery, and the electrolyte of the zinc-manganese battery mainly comprises ammonium chloride, zinc chloride and water in certain proportion. If the sealing performance of the battery is poor, water in the electrolyte is volatilized to influence the normal operation of the battery; oxygen in the air also enters the interior of the cell to oxidize the zinc and reduce the service life of the cell. Therefore, the sealing plays an important role in the battery, and the quality of the sealing directly determines the quality of the zinc-manganese battery.
At present, the zinc-manganese battery sealing compound mainly comprises three types, namely an asphalt series, a rubber series and an epoxy series, and the asphalt series battery sealing compound has good cohesiveness and ageing resistance, but has certain environmental protection problem; the rubber series battery sealing compound has good creep resistance and sealing performance, can improve the storage stability of the battery, but has much higher cost than the asphalt series; the epoxy series battery sealing compound also has the problems of high brittleness, poor impact resistance and low peeling strength.
