常见的银锌电池通常描述为用不锈钢制成一个由正极壳和负极盖组成的小圆盒,盒内靠正极壳一端填充由Ag_2O和少量石墨组成的正极活性材料,负极盖一端填充锌汞合金作负极活性材料,电解质溶液为浓KOH,溶液两边用羧甲基纤维素作隔膜,将电极与电解质溶液隔开,银锌电池属于碱性高能电池,既可做成二次电池,也可做成一次电池。这种电池的优点是内阻小,能量密度高,工作电压平稳,特别适宜高速率放电使用,因而使用广泛,目前以银锌电池为背景的试题中有关电池反应的表达方式主要有:
Common silver-zinc batteries are usually described as a small box made of stainless steel and composed of a positive electrode case and a negative electrode cover, one end of the positive electrode case being filled with a positive electrode active material composed of Ag 2 O and a small amount of graphite, one end of the negative electrode case is filled with a zinc amalgam As the negative active material, the electrolyte solution is concentrated KOH, the solution on both sides with carboxymethyl cellulose as a separator, the electrode and the electrolyte solution separated silver-zinc batteries are alkaline high-energy batteries, can be made of secondary batteries can also be done Into a battery. This battery has the advantages of small internal resistance, high energy density, voltage stability, especially suitable for high-rate discharge, which is widely used, the current silver-zinc battery as the background of the questions on battery reaction expression are:
