Yu Jingmin, executive deputy general manager of SAIC Passenger Cars, revealed in an interview with the media that the all-solid-state battery independently developed by SAIC will first be mounted on MG。The car is expected to go on sale in the second quarter of 2025.。He also mentioned that the upcoming electric MG S5 model will be launched in November this year。

Last year, a number of Chinese companies issued statements on solid-state batteries.。To date, no one has been able to produce a commercial all-solid-state device.。Joining international players such as Mercedes-Benz, BMW, Porsche, Hyundai-Kia, Nissan and Toyota, they claim to be working on such technologies and claim that the vehicle will have a range of more than 1,000 kilometers。

The key difference between solid-state batteries and existing types of batteries is that the electrolyte in solid-state batteries, as the name suggests, is solid, while the electrolyte in current batteries is liquid。This allows the battery to reduce the volume by 40% and the mass by 25% without the diaphragm, thereby increasing the energy density。Such batteries claim to have a longer service life, with up to 45,000 cycles, and can be used in a wide temperature range of -25 ° C-60 ° C。Solid electrolytes are non-flammable, non-corrosive or non-volatile, which makes them safer and prevents any risk of leakage。

The main problem in commercializing solid-state batteries is to be able to produce them cheaply enough through mass production。It is estimated that the Battery S will debut on the high-end MG model in 2025, possibly the Cyber GTS that was unveiled in Goodwood earlier this year。
