摘要
以2-苯基-1-基1H-咪唑-1-磺酸酯(PHS)作为电解液添加剂,用于LiNi_(0.8)Mn_(0.1)Co_(0.1)O_(2)(NCM811)/石墨软包电池中。充放电测试和电化学测量的结果表明,PHS的添加可以提高NCM811/石墨软包电池的常温、低温和高温循环性能,令电池能够在-20~60℃的温度范围内工作,极大地提升了锂离子电池的应用范围。
2-Phenyl-1H-imidazole-1-sulfonate(PHS)was used as an electrolyte additive for LiNi_(0.8)Mn_(0.1)Co_(0.1)O_(2)(NCM811)/graphite pouch battery.The results of charge/discharge test and electrochemical measurement showed that the addition of PHS to the electrolyte improves the cycle performance of NCM811/graphite pouch battery at ordinary,low,and high temperatures,and enables the battery work at the temperature from -20℃ to 60℃,widening the application scope of lithium-ion batteries.
