Description
Technical Field
The utility model relates to an alkaline battery especially relates to an alkaline zinc-manganese dioxide battery who prevents the inside short circuit of battery.
Background
The traditional alkaline zinc-manganese dioxide battery structure generally comprises a battery steel shell, one end of the battery steel shell is sealed and protrudes outwards to form a positive terminal, the other end of the battery steel shell is provided with a negative current collector assembly, an isolation pipe is coaxially sleeved in the battery steel shell, one end of the isolation pipe close to the positive terminal is sealed, an annular cavity between the battery steel shell and the isolation pipe is filled with a pressed positive ring, and the isolation pipe is filled with negative zinc paste. Because the air is remained at the part of the positive terminal which protrudes outwards relative to the bottom of the positive ring, the space utilization rate is reduced, and the oxygen absorption corrosion of the negative calamine cream is easily caused; in addition, when the battery is subjected to severe vibration/impact, the cathode zinc paste easily penetrates through the bottom of the isolation tube and overflows, so that the internal short circuit of the battery is caused.
