KATHMANDU: GAC has built China’s first large-capacity all-solid-state battery production line. State media confirmed the facility is now operational and producing 60 Ah-class vehicle-grade cells on a small-batch test basis.
GAC says these cells can double the driving range of today’s electric vehicles. A car that travels 500 km on one charge could cross 1,000 km once the new cells are used. The company plans small-batch vehicle integration tests in 2026. Mass production is set for 2027 to 2030.
The 60 Ah rating shows how much energy a single cell can store. Higher capacity allows more energy in each battery pack. This supports longer range.
The new all-solid-state cells use solid electrolytes instead of liquid ones. This improves safety and thermal stability. GAC reports an Areal capacity of up to 7.7 mAh/cm², higher than the less-than-5 mAh/cm² level in today’s lithium-ion production.
Research director Qi Hongzhong says the energy density is nearly double that of current batteries. The company also uses a dry anode process that mixes, coats, and rolls material in one step. This raises efficiency and cuts energy use.
The solid electrolyte can tolerate 300–400 °C, compared to about 200 °C in conventional cells.
