電(dian)(dian)(dian)(dian)(dian)池的充(chong)電(dian)(dian)(dian)(dian)(dian)、放電(dian)(dian)(dian)(dian)(dian)時，在(zai)電(dian)(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)(dian)極上(shang)發生(sheng)電(dian)(dian)(dian)(dian)(dian)化學反(fan)應，溫(wen)(wen)度(du)(du)越高，電(dian)(dian)(dian)(dian)(dian)池各活性物質(zhi)的活度(du)(du)增(zeng)加(jia)，電(dian)(dian)(dian)(dian)(dian)解(jie)液粘度(du)(du)降低(di)，電(dian)(dian)(dian)(dian)(dian)阻減小，因此電(dian)(dian)(dian)(dian)(dian)化學反(fan)應容易(yi)進(jin)行，反(fan)之則(ze)(ze)不容易(yi)進(jin)行。放電(dian)(dian)(dian)(dian)(dian)時溫(wen)(wen)度(du)(du)越低(di)，放出容量(liang)(liang)越低(di)，在(zai)特別低(di)的溫(wen)(wen)度(du)(du)下，放出容量(liang)(liang)將(jiang)大幅度(du)(du)下降，溫(wen)(wen)度(du)(du)高則(ze)(ze)相反(fan)；充(chong)電(dian)(dian)(dian)(dian)(dian)時溫(wen)(wen)度(du)(du)越低(di)，充(chong)電(dian)(dian)(dian)(dian)(dian)接受能力(li)越差(cha)，要求(qiu)(qiu)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓較高，才能充(chong)足電(dian)(dian)(dian)(dian)(dian)。反(fan)之溫(wen)(wen)度(du)(du)越高，充(chong)電(dian)(dian)(dian)(dian)(dian)接受能力(li)越好，易(yi)造成過充(chong)電(dian)(dian)(dian)(dian)(dian)，因此要求(qiu)(qiu)降低(di)充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓，才不至于(yu)造成過充(chong)電(dian)(dian)(dian)(dian)(dian)。此溫(wen)(wen)度(du)(du)的變化，直接影響電(dian)(dian)(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)(dian)性能。
