1. Recycling electrolytes under liquid nitrogen conditions
Tong Dongge used the electrolyte (PC) to recycle electrolytes during the recycling of lithium battery recycling; the PC had the largest release rate, and the electrolyte can be completely removed after 2H. In order to avoid fires and explosions, under the protection of liquid nitrogen, the waste battery is cut off and the active substance is removed. Place the active substance in an electrolyte solvent such as PC for a period of time to immerse the electrolyte, and then filter in an inert atmosphere. PC can be recycled and reused multiple times. The recycled electrolyte is purified according to the situation and recycled LIPF6.
2. High -temperature thermal disintegration wave electrolytic solution
At this stage, most experimental studies have not attached enough attention to the electrolyte. The high temperature thermal solution or baking lithium battery is used. Due to the low thermal solution temperature of the electrolyte (about 180C), it will be freely decomposed and volatilized by the electrolyte. Toxic gases such as HF, LIF, etc., during the recovery of large -scale lithium batteries, need to increase secondary treatment of tail gas.
3. Alkaline solution treatment
Zhao Dongjiang and others use dilute alkali water soaking monomer batteries. HF generated by electrolytes will have the following reactions: HF
+Naoh → NAF+H20, and then crushed the battery. This processing method can effectively reduce the generation of HF, but it cannot achieve the recovery of fluoride electrolytes.
4. NMP processing electrolyte
The electrolyte of the liquid is dispersed in the gap between the electrode and the diaphragm. Therefore, the appropriate solvents can be selected. Recycling cycles use solvents, and the remaining is pure electrolyte. The boiling point should be lower than the decomposition temperature (about 80C) of the electrolyte lithium salt, and it should be a water -free operation. In this way, you can obtain the maximum recycling value of electrolytes with economic environmental protection.
Organic solvents are the main part of the electrolyte, which is closely related to the performance of the electrolyte. Generally, the high -agent constant solvents solvents are mixed with low viscosity solvents; commonly used electrolyte lithium salt includes lithium methalotic acid From various aspects such as cost and safety, lithium hexifluoropensive is the main electrolyte adopted by commercial lithium -ion batteries; the use of additives has not been commercialized, but it has always been one of the research hotspots of organic electrolyte.
