ABSTRACT:
A battery includes 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. The container includes a breakable portion which is breakable such 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 includes a variable throttle for the gas which is elastically deformable by the pressure in the container such that the gas is allowed to flow out of the container.
