Chinese Brand Unveils Revolutionary 808-Mile Solid-State Battery | Carscoops
Solid-state batteries like this one should have the ability to charge significantly faster than conventional cells.
A new battery has reached an energy density of 600 Wh/kg, which is twice that of today's best cells.
Chery claims that the chemistry used in this battery prevents fires and remains operational even when submerged in water.
Other Chinese companies, such as BYD, are also working hard to advance solid-state technology.
Chery has now entered the solid-state battery competition, presenting a prototype battery pack that could extend an EV’s practical range to 1,300 km (808 miles). The technology is set to enter pilot production next year, with a full launch planned for 2027.
Developed by the Chery Solid-State Battery Research Institute, this new battery utilizes an in-situ polymerized solid electrolyte system paired with a lithium-rich manganese cathode.
The company reports an impressive energy density of 600 Wh/kg, approximately double the output of the highest-performing non-solid-state batteries available in China.
Chery’s solid-state battery pack is touted to be significantly safer than conventional batteries, continuing to operate normally even after being pierced with nails or a drill.
This chemical composition eliminates the risk of thermal runaway completely, allowing the pack to function even when submerged in water.
While Chery has not specified the charging speed of its advanced battery, it is expected to be quicker than the traditional Lithium Iron Phosphate (LFP) and Nickel Manganese Cobalt (NMC) packs commonly used in current electric vehicles.
In a recent summit, Chery revealed details about the new battery and announced that it had sold over 2 million cars, with European sales more than doubling to 145,000 units.
The Chery Group has maintained its position as the best-selling Chinese brand internationally for the 22nd consecutive year.
Main competitor BYD is also focused on developing its own solid-state batteries. Earlier this year, it stated that its solid-state packs will be available for mid- and high-end electric vehicles by 2027, with plans to introduce them to lower-priced models between 2030 and 2032.
BYD has not shared many technical details about its cells, but it will likely aim to compete with Chery.
