BATTERY

摘要

In a battery comprising, a pair of an anode electric power generating source element and a cathode electric power generating source element for generating an electric power, and a container receiving therein the electric power generating source elements and including a breakable portion which is breakable in such a manner that a gas from at least a part of the electric power generating source elements is allowed to flow out of the container therethrough when a pressure in the container increases excessively, the battery further comprises a variable throttle for the gas which is elastically deformable by the pressure in the container in such a manner that the gas is allowed to flow out of the container.
