ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To increase electrolyte leakage resistance and capacity of a battery by setting an inner case having a reverse hat-shaped cross-section and holes on the side within a battery case. CONSTITUTION:An inner case is formed in the form of a reverse hat by connecting a flange 10 and a central flat part 11 with a circular side 12 and four holes are installed on the side 12. The compression ratio and the deformation of a gasket which are an important factor of electrolyte leakage resistance are retained in almost the same degree as those of a thin battery and electrolyte leakage resistance is stabilized. Since holes are installed on the side of the inner case, a space between a battery case and the inner case can be utilized as an electrolyte reservoir, and the capacity of a battery is increased.
