Anhui Anwa New Energy Technology, a company backed by Chinese automaker Chery, has announced the production of its first batch of solid-state battery prototypes in China. Founded in June 2020, Anwa’s shareholders include Chery New Energy (9.89%) and leading battery manufacturer Gotion High-Tech (5.89%).

According to domestic media reports, Anwa completed production of these engineering samples at its facility in the Wuhu Economic and Technological Development Zone. These first-generation batteries reportedly meet the new "No Fire No Explosion" safety standards and deliver an energy density of 136 watt-hours per pound. The company plans to eventually ramp up to gigawatt-hour-level production of future-generation batteries.

This milestone follows Chery Group’s October 2024 announcement outlining its intentions to enter solid-state battery manufacturing—a plan now taking shape as Anwa’s initial battery packs come off the production line. Figure 1 shows Solid-State Batteries.

Innovative Manufacturing Process Cuts Energy Use and Costs

Anwa's factory features a fully integrated production line spanning over 115 feet, operating at a speed of around 66 feet per minute [1]. The line includes eight processes such as automated electrode coating, diaphragm lamination, and dynamic heat sealing. It uses laser slitting to minimize dust and has an annual production capacity of 1.25 GWh.

To further improve efficiency, Anwa has adopted a five-step dry manufacturing technique that reduces energy consumption by 20% and cuts fixed asset investment by 30%. This streamlined, eco-friendly approach supports more sustainable and cost-effective battery production.

Looking ahead, the company plans to expand its operations by building a 5 GWh solid-state battery R&D center and a fully automated, integrated production line to support larger-scale manufacturing and accelerate innovation.

Roadmap to Higher Energy Density: Mass Production by 2027

While its first-generation solid-state batteries offer an energy density of 136 Wh/lb, Anwa has already started trial production of second-generation packs targeting 181 Wh/lb. This marks a major step forward in storage capacity and energy efficiency.

By 2027, Anwa aims to begin mass production of third-generation solid-state batteries, with a projected energy density of 227 Wh/lb. These advancements could significantly enhance electric vehicle range and performance, while also helping to lower production costs and make EVs more accessible.
