JAKARTA GAC Group from China has officially operated the first production line for large-capacity solid-state battery cells aimed at electric vehicles. This step gained global attention as one of the important milestones in the development of solid-state-based electric vehicle battery technology.

R&D Research Director Qi Hongzhong, said that the solid-state battery cell now has an energy density that is almost double compared to conventional lithium-ion batteries. The area capacity reaches up to 7.7 mAh/cm2, up from less than 5 mAh/cm2 on traditional wet batteries.

Furthermore, the dry anode method (dry anode) which combines blending of smooth, coating, and rolling into one step has been implemented in the production process. So an innovation that allows for higher efficiency and reduced energy consumption in cell manufacturing.

With this technology, GAC Group estimates that electric vehicles currently have a distance of about 500 km in one charge could increase to more than 1,000 km. As reported by Arena EV, Wednesday, November 26.

However, the commercialization stage is still on its way. Small-scale production of vehicle cells has begun, and integration into vehicles is planned to be carried out through trials in 2026.

After that, the GAC Group targets mass production to gradually start between 2027 and 2030. The implementation of large-scale production for solid-state batteries like this presents a number of challenges, including securing the supply chain of solid electrolyte materials and validation of long-term performance in various environmental conditions.

With the launch of this route, the GAC Group put itself in a strategic position in the global competition of electric vehicle batteries. With this range, drivers in general may only need to charge their electric vehicles once or twice a month.
