一类混合锂/钠离子电池
摘要：
本发明公开了一类混合锂/钠离子电池，其中正极材料为钠基材料，可作为锂离子电池正极材料，其分子式为Na3(VO)2(PO4)2F，负极材料为锂离子电池常见负极材料。该混合锂/钠离子电池中正负极片的活性物质质量比为2.0‑3.0，电解液为1M LiPF6/EC+DMC+DEC(体积比1:1:1)，LiPF6/EC+DMC(体积比1:1)，LiPF6/EC+DEC(体积比1:1)等。本发明提供的混合锂/钠离子电池价格低廉，电化学性能优异，且在低温环境下也具有良好的性能，拓宽了其适用范围。
摘要（英）：

The invention discloses a hybrid Li/Na ion battery. A cathode material is a Na-based material and can serve as a cathode material of a Li ion battery, and the molecular formula of the material is Na3(VO)2(PO4)2F; an anode material is a common anode material of the Li ion battery. The mass ratio of active materials of a positive plate to a negative plate in the hybrid Li/Na ion battery is 2.0-3.0;an electrolyte adopts 1M LiPF6/EC+DMC+DEC (in the volume ratio being 1:1:1), LiPF6/EC+DMC (in the volume ratio being 1:1) or LiPF6/EC+DEC (in the volume ratio being 1:1). The hybrid Li/Na ion batteryhas excellent electrochemical performance, has good performance even in a low-temperature environment and is low in cost, and the application range of the battery is broadened.
