Abstract
The organic electrolyte cell that is suitable for application of direct current backup of pulse load with load width on the order of milliseconds and has higher backup capability than the conventional design is achieved by setting the product R·C of an impedance R (Ω) at 1 kHz and a capacity C (F) is in a range from 0.00002 to 0.05, and improving the balance of voltage drop during discharge over a specified load width on the order of milliseconds.
