China has completed its first large-capacity all-solid-state battery production line, marking a technical step forward for its electric-vehicle supply chain, according to state media reports. The line, developed by GAC Group, is currently producing 60 Ah+ vehicle-grade solid-state cells on a small-batch test basis as the company prepares for wider deployment later this decade.
The 60 Ah+ designation refers to the capacity of each cell, with higher ampere-hour ratings generally allowing greater energy storage when assembled into a full battery pack. GAC said the solid-state cells are designed to support future electric vehicles with ranges beyond 1,000 km, compared with today’s typical 500 km.

“The energy density of the new solid-state cells is nearly double that of conventional batteries,” said Qi Hongzhong, GAC’s research director. The company reports an areal capacity of up to 7.7 mAh/cm², higher than levels typically achieved in traditional liquid-electrolyte lithium-ion manufacturing.
GAC is employing a dry anode production method that combines mixing, coating, and rolling into one process step. The company says this approach improves manufacturing efficiency and reduces energy consumption. The solid electrolyte material used in the cells can withstand temperatures of 300–400 °C, compared with about 200 °C for liquid-electrolyte systems, improving thermal stability.

Pilot vehicle integration tests are scheduled for 2026, followed by a ramp-up toward mass production between 2027 and 2030. While the development represents progress toward commercial solid-state battery adoption, analysts note that large-scale rollout will require investment in materials supply, verification of long-term durability, and continued cost reduction.
