摘　　要：针对现有标准中有关锂离子电池循环测试方法的不足,通过尝试改变温度、提高充电上限电压、降低放电截止电压和增加充放电电流等试验方法探究锂离子电池循环新加速方法;分析电流加速循环曲线并拟合方程,形成新评估方法。Disadvantages of lithium-ion battery cycling test methods are analyzed in the existing standards. Then the new assessment method of lithium-ion battery accelerated eirculation is explored by changing temperature, increasingthe maximum charging void, reducing the end-of-charge voltage and enhaneing the charging and discharging current. Morever, new assessment is done by analyzing the curve of era-rent accelerated citation and fitting equation.
