Abstract
Results of evaluation are reported on cycle life/power performance of square lithium/vanadium oxide secondary batteries (25Wh class) trially manufactured as a basic unit for the battery energy storage system which can be installed at home. Experimental results of charge/discharge cycle and power characteristics verify that the battery is highest in performance of all the large capacity lithium secondary batteries which have been made public. The lithium secondary battery with a large capacity more than 10Wh by operation of 50% DOD (depth of discharge) achieves 420 cycles, the highest level. The amount of energy taken out by about one-hour rate discharge is reduced only to about 85% of that by 8-hour rate discharge, which is a favorable result as the lithium secondary battery which operates at normal temperature. However, at the end of one-hour rate discharge, some of the battery surface temperatures rise about 10{degree}C, and this may cause inhibition in the structure as a pair battery. The following method is suggested for improvement: thickness of the cathode of the main heating part is reduced to promote thermal radiation, and the cathode area is enlarged to decrease the current density. 9 refs., 9 figs., 4 tabs.
