Chinese automaker Chery has made a significant stride in electric vehicle technology by unveiling a solid-state battery with an energy density of 600 Wh/kg, promising an impressive 800-mile range. This development comes on the heels of Huawei’s patent for a solid-state battery capable of a 5-minute charge and a 3,000km range, revealed earlier this year, sparking an industry race among Chinese firms to dominate next-generation battery advancements.
Chery’s Solid-State Battery Unveiling
On October 19, 2025, Chery, a leading Chinese automaker, officially announced its new solid-state battery technology. This battery, with an energy density of 600 Wh/kg, is a significant leap forward in power storage efficiency compared to traditional lithium-ion cells. The unveiling underscores China’s commitment to automotive innovation, with Chery planning to integrate this technology into its vehicle lineup to enhance driving capabilities.
Promised Range and Performance
The solid-state battery from Chery promises an impressive 800-mile range on a single charge, potentially revolutionizing long-distance travel in electric vehicles. The high energy density of 600 Wh/kg enables this extended range by allowing more energy storage in a compact form, thus eliminating the need for larger battery packs. This performance could effectively address common EV limitations like range anxiety, making long-distance driving more feasible without the need for frequent recharges.
Huawei’s Competing Patent
Earlier this year, on June 18, 2025, Huawei secured a patent for a solid-state battery that offers a staggering 3,000km range, equivalent to nearly 1,864 miles. The patent also includes a rapid 5-minute charging capability, which could drastically reduce downtime for electric vehicle users compared to current standards. This development from Huawei underscores its shift from telecommunications to automotive tech, leveraging battery patents to influence global supply chains.
Industry Race Sparked by Innovations
The 3,000km solid-state battery patent from Huawei has ignited an industry race, prompting competitors like Chery to accelerate their own advancements in battery technology. The 5-minute charge feature in Huawei’s design sets a new benchmark for fast-charging infrastructure, pressuring the sector to adopt similar rapid-recharge solutions. Overall, these Chinese innovations are fueling a broader competition, with firms racing to commercialize high-density solid-state batteries for widespread EV adoption.
Technological Advantages of Solid-State Batteries
Solid-state batteries, such as Chery’s 600 Wh/kg model, replace liquid electrolytes with solid ones, leading to improved safety and stability during operation. The 800-mile range promised by Chery demonstrates how solid-state tech can achieve higher energy densities without compromising vehicle weight or size. Huawei’s patent similarly emphasizes the benefits of solid-state batteries, with the 3,000km range potentially enabling ultra-long-haul electric transport applications.
Implications for China’s EV Market
Chery’s unveiling on October 19, 2025, strengthens China’s dominance in EV battery production, potentially leading to the export of the 600 Wh/kg technology to global markets. The industry race ignited by Huawei’s patent announcement on June 18, 2025, is accelerating domestic investments, with both companies contributing to reduced reliance on foreign battery suppliers. These advancements could lower EV costs and boost adoption rates in China, where solid-state batteries like those from Chery and Huawei promise superior range and charge times for mass-market vehicles.
