PURPOSE:To prevent bulging and decrease of performance of a battery by installing a space equivalent to 10-30% of electrolyte volume inside the battery in an inorganic electrolyte battery. CONSTITUTION:In the figure, 1 is a negative electrode comprising lithium, 2 is a separator of glass fiber nonwoven fabric, and 3 is a positive electrode consisting of a carbon porous molding body. An electrolyte obtained by dissolving 1.8mol/l aluminum lithium chloride in thionyl chlorideis is used. Thionyl chloride also acts as a cathode active mass. A space is usually installed between a seal and a power generating element, that is, in the place indicating by 8. In a battery having a space of 10% volume ratio to the electrolyte, little bulging due to expansion of the electrolyte appeares. When volume ratio is 30% or less, discharge capacity is almost same as that of conventional battery. |
