摘　　要： 研制了电解电容器工作电解液中主溶质支链羧酸铵盐,并探讨支链羧酸铵盐与直链羧酸铵盐性能的差异.分别以两种羧酸铵盐为主溶质配制两组工作电解液,在相同条件下做对比实验得出:支链羧酸铵盐比直链羧酸铵盐达到闪火的时间短7 s,电导率大260μs.cm-1,闪火电压高8 V.用以上两组工作电解液装配铝电解电容器,并进行装灯应用试验,经125℃,2 500 h后直链羧酸铵盐组电容器△C:-8.4%,△tg:δ1 647%,而支链羧酸铵盐组电容器△C:-2.2%,△tg:δ165%,表明用支链羧酸铵盐的电容器性能优于用直链羧酸铵盐的电容器. This paper develops a branch-chain organic acid salt as main solute used in drive electrolyte of electrolytic capacitor and discusses the differences of performance between branch-chain organic acid salt and straight-chain organic acid salt. Using the two organic acid salts to compound two group drive electrolytes, test result was obtained under the same condition： comparation between straight-chain organic acid salt and branch-chain organic acid salt, the latter＇ s spark generated time was shortened by 7 s, and conductivity increased 260μs · cm^-1 , and spark generated voltage augmented 8 V. Using the two electrolytes to fabricate aluminum capacitor, after 2 500 h long life test under 125℃, result was gained： capacitor using straight-chain organic acid salt, △ C ： - 8.4% , △tgδ ： 1 647% ; capacitor using branch-chain organic acid salt, △ C ： - 2.2% , △ tgδ ： 165%. The results mentioned above indicate that branch-chain organic acid salt has better performance than straight-chain organic acid salt.
