Analysis of the important components of the electrolyte of lithium iron phosphate battery

Currently, lithium iron phosphate batteries on the market urgently use lithium perchlorate, lithium fluoride salt, lithium hexafluorophosphate and so on. Batteries made of lithium perchlorate are not effective at low temperatures and may explode. 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. The battery made of lithium hexafluorophosphate has good battery performance, no explosion hazard, and strong applicability. The future solution of waste batteries is relatively simple and ecologically friendly. Therefore, the future direction of batteries made of lithium hexafluorophosphate is very broad. Lithium iron phosphate battery.jpg1. Vinyl carbonate: Molecular formula: C3H4O3, transparent and colorless liquid (>35℃), crystalline solid at room temperature, it is a good solvent for polyacrylonitrile and polyvinyl chloride. 2. Propylene carbonate, colorless, odorless, or light yellow translucent liquid, soluble in water and carbon tetrachloride, and miscible with ether, acetone, benzene, etc. This product should be stored in a cool, ventilated, dry place, far away from fire, and stored and transported in accordance with the regulations of general low-toxic chemicals. 3. Diethyl carbonate, a colorless liquid with a slight odor; vapor pressure 1.33kPa/23.8°C; flash point 25°C (flammable liquid can volatilize into vapor and run into the air. 4. Dimethyl carbonate is a A non-toxic, environmentally friendly, and versatile chemical raw material; at the same time, it has a higher evaporation temperature and a faster evaporation rate. 5. Ethyl methyl carbonate, a colorless and translucent liquid, is a high-tech, high-additional liquid that has emerged in recent years A valuable chemical product, an excellent solvent for lithium battery electrolyte, this product should be stored in a cool, ventilated, dry place, and stored and transported in accordance with the regulations for flammable chemicals. 6. Lithium hexafluorophosphate, white crystal or powder, with strong deliquescence; Analysis when exposed to air or heating, lithium hexafluorophosphate is quickly analyzed in the air due to the use of water vapor when exposed to air or heated, and PF5 is released and white smoke appears. 7. Phosphorus pentafluoride is a phosphorus halide compound. Phosphorus pentafluoride It is a colorless malodorous gas under normal temperature and pressure, which has strong irritation to the skin, eyes, and mucous membranes. Phosphorus pentafluoride is used as a catalyst for polymerization. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
