Chery 600 Wh/kg solid-state battery: Technical review, scope

Chery announced an all-solid-state battery module with a density of 600 Wh/kg, giving a theoretical range of more than 1,500 km and an expected practical range of about 1,300 km. The battery passed the nail penetration and electric drill tests, Chery will start testing it next year and plans to expand its deployment in 2027.

According to Car News China, Chery has just announced its self-developed all-solid-state battery module, achieving an energy density of 600 Wh/kg. This is one of the highest levels ever announced by a Chinese automaker, opening up expectations of superior travel range and new safety standards for electric vehicles.

In theory, electric vehicles using this battery pack can reach more than 1,500 km/charge, with an expected actual operating range of about 1,300 km. Chery said the battery still maintains its ability to supply electricity after harsh tests such as nail penetration and damage by electric drill without catching fire or producing smoke. The company will start testing from next year and plans to expand the deployment scale by 2027.

Modular “design”: towards high energy density and intrinsic safety

Chery describes this as an all-solid-state battery module developed entirely by the company. The technical focus is on increasing the energy density to 600 Wh/kg, while improving the intrinsic safety of the solid cell. At the system level, a high-density module gives automakers more flexibility in packaging, compatibility with multiple platform configurations, and optimized mass distribution, which promises benefits in terms of usable space and operating efficiency.

The big challenge for solid-state technology, according to Car News China, is cost. The current average price of all-solid-state batteries is about 2.8 times higher than that of liquid-electrolyte lithium-ion batteries, mainly due to the high cost of sulfide materials and limited production capacity. This shows that the design problem is not only at the cell/module level but also at the production line and scale.

The “interior” of the experience: fewer charges, hopefully reduced range anxiety

A theoretical range of over 1,500 km and a projected real-world range of around 1,300 km, if confirmed in operation, could change consumer expectations of electric vehicles. With significantly increased range per charge, daily driving and intercity travel would become less dependent on a dense charging network. A high-density battery pack also promises good capacity retention across a wide range of conditions, improving the overall experience.

Energy efficiency: 600 Wh/kg and range 1,500 km (theoretical)

The 600 Wh/kg figure is currently among the highest claimed by a Chinese automaker. From a usage perspective, this translates directly into a longer operating range. Chery claims a theoretical range of over 1,500 km per charge; the real-world range is expected to be around 1,300 km, depending on operating conditions. This is a significant jump for EV configurations geared towards long-distance and heavy loads.

Safety and technology: passed nail penetration test, electric drill

Chery says its solid-state modules maintain power after undergoing harsh tests like nail penetration and damage from an electric drill without catching fire or producing smoke. That’s a key difference from traditional concerns about batteries overheating. If the results are replicated in mass production, market acceptance of solid-state batteries could improve significantly.

Price and positioning: 2.8x cost, 2027 roadmap

Regarding commercialization, Chery plans to conduct trial operations from next year and expand its scale in 2027. If on schedule, the company can create an advantage in the solid-state battery race, surpassing big names such as BYD and CATL in this technology field.

On a macro level, according to Car News China, global solid-state battery production could reach 614 GWh by 2030, accounting for more than 10% of total battery production. The market size is forecast to exceed 250 billion yuan (about 34 billion USD) by the end of the decade. However, cost remains a major barrier, with the average price of all-solid-state batteries being about 2.8 times higher than that of liquid electrolyte batteries, mainly due to expensive sulfide materials and limited production capacity.
