The purpose is to improve leakage resistance.

イソブチレンなどが用いられていた。Conventionally, as in Japanese Patent Application Laid-Open No. 54-1830, there have been cylindrical alkaline batteries in which adhesive is filled between the packing and the sealing plate, between the packing and the positive electrode can, or between the banking and the current collector rod. Ta. As adhesives, low molecular weight polyfluoroalkoxyphosphazenes, fatty acid polyamide resins, low polymerized fluororesins, polyisobutylene, etc. have been used.

へ出るのが主な原因であった。4'tL of electrolyte of a cylindrical alkaline battery is a positive electrode can,
There are two causes: the liquid leaks out through the negative electrode current collector rod, and the liquid leaks through the negative electrode current collector rod. i! The main cause of leakage during long-term storage of ponds was electrolyte leaking out through current collector rods.

易くなる問題点がおるからである。However, conventionally used adhesives attempt to achieve leakage resistance by utilizing their sealing properties, so while they can be expected to be somewhat effective at low temperatures, they become less effective when the humidity increases during storage. , its improvement was necessary. This is because as the temperature rises, the pressure inside the battery weakens and the sealing performance weakens, and the viscosity of the electrolyte decreases, making it fluid and prone to leaking to the outside of the battery.

By applying an adhesive made of pitch remover arusul 7-ionized polyethylene, it completely prevents electrolyte from leaking through the collector rod and out of the stain pond, improving leakage resistance during storage. The purpose is to obtain a cylindrical alkaline battery with a

のである。[Function] Since the present invention uses an adhesive made of pitch and chlorosulfonated polyethylene between the current collector rod and the packing, the electrolyte in the gelled negative electrode crawls up the gold W4 surface of the current collector rod. Also, due to the strong water repellency of the pitch and chlorosulfonated polyethylene adhesive and its ability to fill even the smallest gaps, it has an extremely strong ability to prevent the passage of the 1y# liquid, and can withstand up to 15' without allowing the electrolyte to pass through completely. 4 KL properties are greatly improved.
