SMM: a few days ago, according to overseas media reports, Mercedes-Benz will take the lead in carrying solid-state batteries on the city electric bus-eCitaro G, becoming the first bus of its kind to be equipped with innovative solid-state batteries. In response to the passenger car market, Mercedes-Benz officials said: "cars based on solid-state batteries did not appear until the middle of this century."
There is some reason for such caution. At present, many automakers are studying solid-state battery technology, but the results do not seem to be ideal. Toyota has previously said that mass production of solid-state batteries will be subject to a series of restrictions by 2025. Not only that, Fisker also said it would postpone the use of solid-state battery technology.
Earlier this year, it was reported that Daimler and Canada's Quebec Hydro announced a partnership to jointly develop solid-state battery technology. The purpose of the cooperation between the two sides is to test new materials and speed up the mass production of solid-state batteries. Compared with the technology promised by other companies, Mercedes' solid-state battery technology also seems to have encountered bottlenecks in a wide range of applications.
Because the use path of urban bus is consistent, it can facilitate the replenishment of battery energy in the process of use, so Mercedes-Benz intends to take the lead in applying solid-state battery technology on bus models to verify the effect of this kind of battery.
As one of the automakers transforming into electrification, the Mercedes-Benz EQC, the first all-electric car of Mercedes-Benz, has already been on the market, which marks a key step towards the development of electrification. According to the plan, Daimler will launch more than 20 new plug-in hybrid and all-electric vehicles in 2020, and more than half of the group's sales in 2030 will be new energy vehicles.
Here is a brief introduction to solid-state batteries, which refer to battery products that use solid materials such as ceramics, glass or chemical polymers as batteries instead of electrolytes. Solid-state batteries are characterized by high safety, small battery packs and longer vehicle mileage. However, this kind of battery also has some problems, such as short service life, low conductivity, high manufacturing cost and so on. Although the application prospect of solid-state battery is promising, it remains to be seen when it is put into the passenger car market.
