✦ Synopsis
Porous 6-nylon+arbon composite was made, and a button type battery, ZnlZnI, +NH,CII catlon exchanging membranelZn1, + NH,ClII,-porous 6-nylon<arbon composite, havmg mner volume of 2 7 cm3 and electrode area of 3 cm2 was prepared Most part of internal resistance of the battery origmated from the membrane and the electrlcal resistance of the membrane was strongly decreased with Increase m NH,CI concentration When an aqueous solution containing 2 M of ZnI, and 6 M of NH,CI and Selenuon CMV with thickness of0 13 mm were used as the electrolytic solution and the catlon exchanging membrane, respectively, the battery had energy density of 72 W hdm-', current efficiency of almost lOO%, and energy efficiency of 88% The battery was rechargeable more than 380 times with decrease m the dischargmg capacity to about 80% and 75% of that ofearly cycles at 200"' and 3801h cycles, respectively Self-dischargmg rate of the battery was about 10% per month Open clrctut voltage of the battery after chargmg showed shght dependence on temperature (dV/dT=OOOO5), and the battery showed good chargmg-dlschargmg behavlour m a temperature range of 5-50°C
