Application status of high-voltage lithium batteries
Generally speaking, high-voltage lithium batteries refer to batteries with a single charging cut-off voltage higher than 4.2V, such as: lithium batteries used in mobile phones, the cut-off voltage has developed from 4.2V to 4.3V, 4.35V, and then to 4.4V (Xiaomi mobile phones, Huawei mobile phones, etc.). At present, 4.35V and 4.4V lithium batteries have been maturely used in the market, and 4.45V and 4.5V have also begun to be favored by the market and will gradually develop and mature.
At present, domestic and foreign manufacturers of batteries for mobile phones and other digital electronic products are moving in the direction of high-voltage lithium batteries. Lithium batteries with high voltage and high energy density will have a larger market space in high-end mobile phones and portable electronic devices. Cathode materials and electrolytes are the key materials to improve the high voltage of lithium batteries, among which the use of modified high-voltage lithium cobalt oxide and high-voltage ternary materials will be more mature and common.
With the increase of voltage, some safety performance of high-voltage lithium batteries will be reduced during use, so they have not been used in batches in power vehicles. At present, the battery cathode materials used in power vehicles are mainly ternary materials and lithium iron phosphate. In order to improve the energy density to meet the demand, high-nickel cathode materials such as 811NCM and NCA, high-capacity silicon-carbon anode or improve the utilization rate of battery space are generally selected to improve their energy density and endurance.
