在锌炭贮液电池的使用过程中,即使采用小电流密度放电,放电电压也总是远小于理论值。因此,使电池的结构设计和使用的温度范围、时间受到一定的限制。放电电压和理论值相差较大的原因,除结构因素外,主要是由单体电池的正、负极极化和内部欧姆压降所造成的。内部欧姆压降在锌炭贮液单体电池中是相当小的,而正、负极的极化却是相当严重的。在高、室温放电的末段,低温放电的起始段,它们对放电电压的影响尤为显著。但是, In the use of zinc-carbon storage battery, even with a small current density discharge, the discharge voltage is always much smaller than the theoretical value. Therefore, the structure of the battery design and use of the temperature range, time subject to certain restrictions. Discharge voltage and the theoretical difference between the larger reasons, in addition to structural factors, mainly by the positive and negative single cell polarization and internal Ohm voltage drop caused by. The internal ohmic voltage drop is quite small in zinc-carbon storage cells, and the polarization of the positive and negative electrodes is quite serious. At the end of the high and the room temperature discharges, the onset of the low temperature discharge has a significant effect on the discharge voltage. but,
