    • In recharging a zinc-halogen secondary battery or battery, zinc dendrite is readily formed on the negative electrode and therefore it has been difficult to form a uniformly thick zinc layer on the negative electrode. This inevitably causes a short cyclic battery lifetime. To overcome this problem, electric pulse treatment is effected at the electrode before dc battery recharging process. In zinc oxide resolving treatment, an electrically positive pulse is applied to the negative electrode. In zinc fine crystal depositing treatment, an electrically negative pulse is applied to the negative electrode. Where the above pulse treatments are effected in combination in the electrolyte including a zinc dendrite inhibitor, a synergistic effect can be obtained.
    • 在对卤素二次电池或电池进行再充电时,负极上容易形成锌枝晶,因此难以在负极上形成均匀的锌层。 这不可避免地导致短暂的循环电池寿命。 为了克服这个问题,在直流电池充电过程之前,在电极处进行电脉冲处理。 在氧化锌分解处理中,向负极施加电正脉冲。 在锌微晶沉积处理中,向负极施加电负脉冲。 在包含锌枝晶抑制剂的电解质中组合进行上述脉冲处理的情况下,可以获得协同效果。
