【摘要】 以葡萄糖为还原剂、聚乙烯吡咯烷酮(PVP)为分散剂,在碱性条件下化学还原硝酸银溶液制备纳米银粉,再通过共沉积掺入到锌负极中,考察制备的锌镍电池的充放电、倍率和循环性能。锌负极中掺入银后,氢气的析出受到抑制,放电电压和容量都得到提高。掺银0.07%的锌负极以1 C在2.0~1.3 V循环30次,放电容量为最高值的46.6%。更多还原

【Abstract】 Nanosilver powder was obtained by reducing AgNO₃ solution in alkaline condition with glucose as reductant.PVP as dispersant,then was doped into Zn anode by codeposition,the charge-discharge,rate and cycle performance of prepared Ni-Zn battery was investigated.After doping Ag,hydrogen evolution was suppressed,the discharge voltage and capacity was elevated.After cycle30 times at 1 C in 2.0 1.3 V,the discharge capacity of Zn anode doped with 0.07% Ag was 46.6% of the maximum value.更多还原
