| 摘 要： | 以乙二醇、季戊IN醇和聚乙二醇为例，用循环伏安和电化学阻抗法研究了多元醇对气相二氧化硅胶体电解液电化学性能的影响。结果表明，添加适量的乙二醇和季戊四醇有利于提高纯铅电极在胶体电解液中的氧化还原电流，降低胶体电解液的电化学转移电阻。但是添加聚乙二醇-6000和添加过量的乙二醇和季戊四醇，不利于胶体电解液电化学性能的提高。添加聚乙二醇-6000不利于形成触变性凝胶。 |

| Abstract: | The effects of glycol,pentaerythritol and polyethylene glycol on the electrochemical properties of gel electrolytes have been investigated by means of cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS).The results show that proper content of glycol and pentaerythritol can help to increase the redox current of the lead electrode and decrease the charge-transfer resistance of the gel electrolyte.The added polyethylene glycol as well as excessive glycol and pentaerythritol cannot im-prove t... |
| Keywords: | gel electrolyte glycol pentaerythritol polyethylene glycol lead-acid battery |
