Abstract
[中文文摘]利用浸渍法在聚丙烯微孔膜( Celgard 2400) 表面涂覆掺有纳米二氧化硅的聚氧乙烯( PEO) , 制备了新型锂电池用复合隔膜. 采用交流阻抗法、扣式电池充放电等实验技术测试了复合隔膜的电化学性能.[英文文摘]New composite seperators for lithium ion batteries were prepared by coating PEO mixed with nanosize SiO2 onto microporous polypropylene( PP) seperators. Highly conductive electrolytes were prepared by soaking them in an electrolyte solution. With these composite separators, the lithium ion cell consisting of Li anode and LiNi0. 8Co0. 2O2 cathode were assembled. The high initial discharge capacity and good capacity retention were obtained through the cell.
