摘要
合成了双草酸硼酸锂(LiBOB),采用核磁共振波谱和元素分析法对其进行分析;将LiBOB与PC+DEC配制成一系列电解液,比较了各种电解液的电导率随温度及浓度变化的规律;用充放电方法研究了几种电解液与石墨负极的相容性。结果表明:采用0.5 mol/L LiBOB/PC+DEC(体积比3∶7)电解液的Li/ARG电池循环性能最好,首次循环效率为79.0%。
Bisoxalatoborate （LiBOB） was synthesized. NMR and elemental analysis methods were used to analyze the property of the LiBOB, electrolytes of LiBOB with PC and DEC were prepared. The change regulation of conductivity of the electrolytes with temperature and concentration was compared. The charge-discharge test was used to examine the compatibility of the electrolytes with ARG anode. The results showed that the Li/ARG battery with the electrolyte of 0.5 mol/L LIBOB/PC ＋ DEC（3 ： 7, vol） had tile best cycling stability aod its initial cycling efficiency was 79.0%.
