Lithium manganese oxide battery can be recharged for 20 minutes, with a battery life of 350 kilometers

　　Lithium cobalt oxide battery). Among the lithium battery materials, it has the highest battery energy density, but it is also the most unstable at high temperatures. When the temperature reaches 180 degrees, the lithium cobalt oxide battery will decompose into oxygen and release a large amount of heat energy. It may explode; BYD uses a lithium iron phosphate battery, the battery material is the most stable, but the energy density is low.

　　Lithium manganate material has more advantages in cost price and energy density

　　Lithium batteries have two key parameters, which are also important reasons that hinder the cruising range. One is the cost of $/Kwh, which is how much electricity is per kilowatt-hour; the other is the energy density of the battery Wh/kg, which is watt-hours per kilogram.

　　In terms of cost price, the current domestic market price of commonly used ternary cathode materials and lithium iron phosphate is about 150,000 per ton, and the price of lithium manganate is about 70,000 yuan; Wang Meng told Chuangyebang that the layered lithium manganate they developed The cathode material is an upgrade of the cathode material in the current market. The market price of the cathode material is about 60,000 per ton. Not only is the price lower, the performance is also significantly improved, and the cost performance is more outstanding.

　　In terms of energy density, the current lithium battery is about $400-500/Kwh, that is, a kilowatt-hour battery costs 400-500 US dollars. Based on the current exchange rate, it is about 2500-3000 yuan per kilowatt-hour. The energy density of batteries produced using lithium manganate cathode materials can reach 500KW/Kg, the self-discharge rate is 0.5%, and the service life is 10 years, while the cycle life of lithium iron phosphate power batteries is between 7 and 8 years.
