The main electrolytes used in lithium batteries are lithium perchlorate, [2] lithium hexafluorophosphate, etc. However, batteries made of lithium perchlorate have poor low-temperature effects and are at risk of explosion. Japan and the United States have banned their use. The battery made of fluorine-containing lithium salt has good performance, no explosion hazard, and strong applicability, especially the battery made of lithium hexafluorophosphate. In addition to the above advantages, the disposal of waste batteries in the future is relatively simple and environmentally friendly. Therefore, The market prospect of such electrolytes is very broad.
