FLAT TYPE ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To prevent increase in internal resistance in the final stage of discharge without sacrifice of discharge capacity of a battery by specifying the volume of a current collector to the inner volume of the battery. CONSTITUTION:The volumn of a positive current collector 7 to the inner volumn of a battery is limited to 0.5-5%. When the volumn of current collector 7 is 0.5% or more, increase in internal resistance in the final stage of discharge can be prevented. When the volumn of current collector exceeds 5%, the volume of active material must be reduced. Therefore, discharge capacity is decreased.
