摘要
选用自制炭黑电极和活性炭电极,与铅酸电池负极并联,制作成超级电池(2 V、0.4 Ah);进行充电接受能力、不同放电倍率、阻抗及循环寿命测试。超级电池的充电接受能力较好,以5 C放电时,炭黑超级电池的容量比普通铅酸电池提高62%;在高倍率部分荷电态下,炭黑超级电池的循环寿命比铅酸电池延长了49%。
Ultra-batteries （ 2 V,0.4 Ah） were assembled with carbon black electrode and active carbon electrode, respectively, then the ultra-batteries were subjected to the tests such as charge acceptance, discharging at different rate, electrochemical impedance spectroscopy and cycle performance. The ultra-batteries exhibited a better charge acceptance ability. The capacity of ultra-batteries increased 62% than that of the conventional lead-acid battery during 5 C discharging. Compared with normal batteries ,the cycle life of the ultra-battery produced by carbon black electrode prolonged by 49%.
