Solid-state Battery

BYD's chief scientist expects solid-state batteries to be widely used in 5 years, starting with high-end models, the first time a BYD executive has spoken publicly on the topic in the last few years.

Nio president previously mentioned that its 150-kWh semi-solid-state battery pack costs about the same as an ET5, which starts at RMB 298,000.

China saw 482.9 MWh of semi-solid batteries installed in May, up 30.9 percent from 369.0 MWh in April, with WeLion the sole contributor, according to an industry association.

Six companies, including CATL, BYD, FAW, SAIC, WeLion and Geely, may receive basic government R&D support, according to China Daily.

Gotion has launched the G-Current, which supports ultra-fast charging, the Stellary Battery, a large cylindrical battery, and announced the Gemstone, an all-solid-state battery.

Deliveries of the regular variants of the IM L6 will begin at the end of May, while deliveries of the variant with semi-solid-state batteries are expected to begin in October.

In a recent wide-ranging interview with CnEVPost, a CATL spokesperson talked about the company's overseas partnership model and its layout for new technologies.

CATL aims to produce all-solid-state batteries in small batches by 2027, but high-volume production will still face challenges including cost, an executive said.

WeLion and JAC Yiwei will work together to develop a model powered by 4695 large cylindrical semi-solid battery cells with a range of 600 km to 1,000 km.

GAC said its solid-state batteries have an energy density of more than 400 Wh/kg and could easily give an EV a range of over 1,000 kilometers.
