Introduction: Nowadays, the process of car electrification is intensifying. Traditional auto companies and emerging entry-level car companies are all involved in the electric car market. The electrification of the whole people is a trend-oriented development in the future. But as the saying goes, "people rely on clothes and horses with saddles", electric cars want to drive well, open 6, the battery can not be too bad, including electric vehicle battery life and battery safety. The state in which electric vehicles can develop depends largely on the development of advanced technologies for batteries.
Nowadays, the electrification of automobiles has become a trend in the world. Whether it is a traditional car enterprise or a new enterprise that has entered the game “barbaricâ€, it has laid out the electric vehicle market. Just as the most important fuel vehicle is the engine, the most important non-battery of electric vehicles is the extent to which the electric vehicle industry can develop to the full extent of battery technology.
Generally speaking, the most important power batteries include lithium iron phosphate battery, lithium manganese oxide battery and ternary lithium battery. Each of these three batteries has advantages and disadvantages:
Ternary lithium:
Advantages: high energy density and high tap density.
Disadvantages: poor safety, poor high temperature resistance, poor life, poor power discharge, and toxic elements (the temperature of the ternary lithium battery increases sharply after charging and discharging, and the oxygen is easily burned after high temperature).
Lithium iron phosphate:
Advantages: long life, large charge and discharge rate, good safety, high temperature, harmless elements and low cost.
Disadvantages: low energy density and low tap density (bulk density).
Lithium manganese oxide:
Advantages: high tap density and low cost.
Disadvantages: Poor temperature resistance, lithium citrate temperature rises sharply after long-term use, battery life is seriously attenuated.
Although there is no battery in the market that combines "high energy density, high temperature and low temperature resistance, long cycle life, good safety and low cost", technology has been improving. In recent years, many "laboratory technologies" have made breakthroughs. Sexual progress. Next, Xiaobian will take stock of the cutting-edge battery technology in the past year, and perhaps there will be a new generation of batteries that will become popular in the future.
