摘要
本文报道了以碱式碳酸镍、碱式碳酸钴和碳酸锂为原料 ,柠檬酸为络合剂的新溶胶凝胶法制备复合锂镍钴氧化物锂离子电池正极材料 .氧气流中制备的LiNi0 .8Co0 .2 O2 具有高的循环容量 (～ 190mAhg 1)
The synthesis and electrochemical characteristics of lithium cobalt nickel oxide as cathode materials for rechargeable lithium batteries were investigated. It was clarified from these investigations that lithium cobalt nickel oxide has been produced from basic cobalt carbonate,basic nickel carbonate, lithium carbonate, and citrate. LiNi 0.8 Co 0.2 O 2 prepared under the stream of oxygen gas showed a higher cycling capacity of (～190 mAhg 1 ).
