摘要
研究了锂离子电池碳纳米管导电剂(CNTs)、电解液对锂离子电池-40℃低温放电性能的影响。以额定容量为2750mAh的INPP78/34/95锂离子电池为例,在-40℃下,负极中添加了CNTS的电池的放电电压平台比负极中添加SP的电池的放电电压平台提高0.17V,低温放电容量提高了7.5%。
The influences of carbon nanotubes（CNTs） and electrolyte at-40℃ discharge performance of Li-ion battery were studied.When discharge at-40℃,the discharge voltage platform of battery of INPP78/34/95（norminal capacity was 2750mAh） with CNTs added into anode electrode was about 0.17V,and higher than the battery with SP added into anode electrode.The discharge capacity was improved 7.5%.
