摘要
本文研究了电解液中添加磷酸对混合动力汽车用铅炭电池性能的影响。通过循环伏安、线性扫描曲线和电池循环寿命测试表明,电解液添加磷酸可显著抑制正极板析氧,但同时也会抑制正极充电反应。所以,混合动力汽车用铅炭电池电解液不适合添加磷酸。
The influences of phosphoric acid added into the sulfuric acid electrolyte on the performances of Pb-C batteries for HEVs were researched.According to cyclic voltammetry（CV）、linear sweep voltammetry（LSV） and cycling life test,the results indicated that phosphoric acid added into electrolyte could inhibit oxygen evolution obviously,but restrain the positive electrode charging reaction meanwhile.So phosphoric acid was unsuitable to be added into electrolyte of Pb-C batteries for HEVs.
