【摘要】 为了提高磷酸铁锂（LiFePO₄）电池的低温性能,采用电导率较高的碳纳米管作为磷酸铁锂电极的导电剂。以LiFePO₄和金属锂为正负极材料,低温性能测试结果表明,碳纳米管在电极中易形成良好的导电网络,减轻电极的极化,能有效改善磷酸铁锂电池的低温放电性能。更多还原

【Abstract】 In order to improve the low temperature performance of LiFePO₄-based batteries,carbon nanotubes（CNTs） was used as a conductive additive of LiFePO₄ cathode,because of its high conductivity.The low temperature performance test results of LiFePO₄/Li batteries showed that CNTs could form better conductive network in the LiFePO₄ cathode and leads to alleviation the degree of polarization,therefore improved the low temperature discharge performance of LiFePO₄/Li batteries.更多还原
