The future of solid-state batteries and pure electric vehicles

As a new generation of battery technology that is expected to replace lithium batteries at that time, solid-state batteries are not only researched and discussed by related organizations and suppliers, but also major auto companies have also set their sights on this technology. It can even be said that the production of solid-state batteries has The electrification layout of auto companies is closely related. Summarizing the reports of major media at home and abroad, it is not difficult to find: 1. As the car company with the highest voice for solid-state batteries, the Volkswagen Group has invested 100 million US dollars in QuantumScape for the development of solid-state batteries, and soon after joining hands with the Ningde era in China, the Volkswagen Group Chief Executive Herbert Dis said that the Volkswagen Group will build a plant in Europe to produce solid-state batteries and is expected to complete mass production in 2024-2025. However, some foreign media believe that the mass group may begin to deploy solid-state batteries at the end of 2020. 2. In 2017, BMW Group joined hands with SoildPower to develop solid-state batteries, and opened collaboration with the domestic Ningde era to deploy electrified models. 3. Toyota is also one of the earliest car companies to develop solid-state batteries. In addition to working with Panasonic, its technical route focusing on sulfide solid electrolytes has also been exposed, and foreign media say Toyota is expected to launch solid-state batteries in 2022. Model. Concentrating on the country, it is the Ningde era and BYD that have reached a partnership with Toyota. Coincidentally, the Ningde era has made initial developments in the field of sulfide solid electrolytes, and BYD applied for a solid lithium battery cathode composite material patent in 2017. Currently, solid-state batteries are being promoted towards commercialization. 4. Hyundai Group has invested in Ionic Materials for the development of solid-state batteries, and Samsung and Dyson are also paying for the latter. 5. Honda’s partner in the field of solid-state batteries is also Panasonic. At the same time, the brand has opened up collaboration with the Ningde era, and Honda and GM also announced that they will jointly develop next-generation battery technology, but in addition to fuel-powered batteries, no more leaks have been made. detail. In addition, some suppliers are also promoting research in the field of solid-state batteries, from Bolloré, Continental, LG, Apple, to domestic BYD, Ningde era, Guoxuan High-tech, Ganfeng Lithium, etc., whether it is a car company borrowing new Technology launches new products, and major suppliers are still competing for the future market share of lithium batteries and speeding up technology development. To a certain extent, they are also racing against time. It is worth mentioning that Qingtao (Kunshan) Power Development Co., Ltd., a start-up company in my country, has established a solid-state battery production line in Kunshan. The annual output of the production line is 100 MWh, and it is planned to increase to 700 MWh by 2020. Compared with a new generation of lithium batteries with a capacity of 250-300Wh/kg, the energy density of its solid-state batteries has exceeded 400Wh/kg.
