Abstract

A battery has a through-hole traversing a battery main body and opened to outside. The battery has a vessel having a central through-hole, and a spiral-shaped electrode, made up of a strip-shaped positive electrode and a strip-shaped negative electrode wound about a cylindrical core a number of times with a separator in-between, is mounted in the battery vessel so that an opening of the cylindrical core is substantially coincident with the through-hole in the battery vessel. The battery vessel is sealed after charging a liquid electrolyte. One or more thin metal plates are inserted and secured in the through-hole, or one or more heat-dissipating fins are radially formed around the opening end of the through-hole. The battery has good heat-dissipating properties and is superior in strength and energy density.
