October 25, 2024: Chinese auto firm Chery has confirmed plans to roll out what it said will be mass production of its own solid-state battery tech by 2027.

The firm announced the move on October 18 at its Chery Global Innovation Conference in Wuhu, China.

Chery said its ‘Kunpeng’ EV battery brand would encompass square-shaped lithium iron phosphate, ternary and large cylindrical ternary batteries — all of which it claimed would be fast charging, long-range and safer than existing lithium ion battery chemistry.

In terms of performance, Chery claimed the batteries would be able to charge at a rate of up to 6C and offer a range of 400km after just five minutes.

“They support PHEV/REEV electric ranges of over 300 km and EV electric ranges of up to 1,200 km,” Chery said. “They also boast an industry-leading 20% longer lifespan.”

Investment in solid-state development has ramped up in recent years, not least in Asia.

Batteries International reported in June that lead and lithium battery giant, Leoch, had signed a framework agreement to cooperate on solid-state tech R&D with China’s Fuzhou University.

Singapore-headquartered Leoch said the move was in line with development of its new energy batteries business — and could nurture training and scientific research on both sides.
