Ternary lithium battery is about to reach the technical bottleneck

At the “2019 China Electric Vehicle Hundreds Meeting” forum held from January 12 to 13, Zhang Hailiang, Chairman and CEO of Skyrim Motors, said in an interview with reporters that the current shortcomings of electric vehicles are driving range and charging. Time, the ternary lithium battery is about to reach the technical bottleneck, and solid-state batteries and fuel cells will be commercialized. Innovative layouts should be used to solve the technical shortcomings of electric vehicles and alleviate users' mileage anxiety.

In 2018, the wholesale volume of new energy passenger vehicles in my country has reached 1.008 million, a year-on-year increase of 88.5%. The development trend of new energy vehicles continues to be good. Zhang Hailiang said that at present, new energy vehicles still need to improve the ability of technological innovation to relieve the anxiety caused by the shortcomings of performance to users. He pointed out that the main shortcomings of electric vehicles are the driving range and charging time. Electric vehicles based on ternary lithium batteries cannot yet meet the needs of large-scale and wide-range long-distance bus, double-shift rental, urban logistics, long-distance transportation and other markets. demand. At the same time, in the context of gradual decline in subsidies, low price advantages and high performance concerns will highlight the contradiction between user needs and the shortcomings of electric vehicles.

Zhang Hailiang predicts that in the next 3 to 5 years, ternary lithium batteries will reach the technical bottleneck, and the commercialization of solid-state batteries and fuel cells will solve the shortcomings of electric vehicle technology. Board, alleviate users’ mileage anxiety. He said that there are many new energy vehicles at present, but there are not many mass-produced models that are actually launched for customers, so the industry reshuffle has not been involved at present.

Zhang Hailiang introduced that Skyrim Motor plans to launch products with significantly improved battery cell energy density in the future. At the same time, it will also launch research on cell materials and manufacturing processes, increase the exploration of solid-state battery vehicle applications, module and pack structure, thermal management, cell technology and other technical iterations, and continue to conduct high-efficiency real-vehicle tests. It is estimated that by 2021, the energy density of Skyline solid-state battery cells will reach 300Wh/kg or more, and the energy density of battery packs will be 220Wh/kg.
