<p>PURPOSE:To prevent the temperature of a storage battery from exceeding the maximum allowable level during its quick charge and discharge by filling a cavity perforated in a terminal with a material that phase-changes at a lower temperature than the maximum allowable level and that is provided with a high phase change potential heat. CONSTITUTION:An assembled pole 3 consisting of positive and negative electrode plates and a separator is housed in a container 1 by dipping it in an electrolyte solution 4. Besides, a cavity 7 is provided in a terminal 5 that is stretched from a strap 6 providing connection between plates and is allowed to penetrate outside the container through a cover 2 strap 6 and in the and said cavity is filled with a material, for example, thymol, etc. that phase-changes at a slightly lower temperature than the maximum allowable level and is provided with a high phase change potential heat. As a result, when the storage battery is overheated by quick charge and discharge, etc., since the material in the cavity 7 phase-changes at a lower temperature than the maximum allowable level and absorbs the heat, the temperature of storage battery does not exceed the existent temperature ths any damage, etc. of the battery can be prevented.</p> |
