Chery Unveils 600 Wh/kg Solid-State Battery Module Targeting 1,300 km Range

Chery's new battery module employs an in-situ polymerized solid electrolyte system paired with a lithium-rich manganese cathode material, a combination that enhances both energy density and safety. This innovation was developed by the Chery Solid-State Battery Research Institute, which has focused on pushing the boundaries of battery technology. The module's resilience was tested under extreme conditions, such as nail penetration and power-drill damage, with the cell maintaining power delivery without catching fire or producing smoke—a significant leap forward in battery safety standards.

The potential impact of this technology is substantial, with Chery outlining ambitious plans for its commercialization. Vehicles equipped with this solid-state battery could theoretically exceed 1,500 km on a single charge, although real-world applications are expected to achieve around 1,300 km. This development positions Chery at the forefront of the global race to commercialize solid-state batteries, a move that could redefine the expectations for long-range electric mobility.

Chery plans to initiate pilot operations with this battery technology in 2026, with a broader rollout anticipated in 2027. If successful, this timeline would allow Chery to outpace major industry players like BYD and CATL, who are also targeting small-scale solid-state production around the same time. The announcement comes amidst Chery's strong performance in exports and revenue, with recent figures showing a 26.2% year-on-year increase in overseas vehicle shipments.

The global landscape of solid-state battery development is heating up, with companies like Toyota and Sumitomo Metal Mining also accelerating their efforts in this arena. According to EVTank, worldwide shipments of solid-state batteries are projected to reach 614 GWh by 2030, representing over 10% of total battery output and creating a market exceeding 250 billion yuan. Chinese research teams, including a group from Tsinghua University, are making strides with their own advancements, further underscoring China's competitive edge in this sector.

Despite the promising technology, the cost of solid-state batteries remains a barrier, currently estimated to be 2.8 times higher than traditional lithium-ion packs. This is largely due to the expensive sulfide materials and low production yields. However, Chery's public debut of its 600 Wh/kg module marks a crucial technical milestone that could drive economies of scale and reduce costs over time. If industrialized successfully, this innovation could significantly advance China's standing in next-generation battery technology and set new expectations for electric vehicle performance.

Chery's unveiling of the solid-state battery module is not just a technical achievement but a strategic move that highlights the company's commitment to innovation and leadership in the EV market. By investing heavily in research and development, Chery is positioning itself to capitalize on the growing demand for long-range electric mobility solutions. As the company moves towards pilot production and broader commercialization, the automotive industry will be closely watching to see if Chery's ambitious targets can be realized.
