Chinese battery manufacturer Gotion High-Tech has completed a 0.2 GWh pilot production line, started in 2024, that has a 90% yield rate for its GEMSTONE all-solid-state battery.

The 2025 iteration demonstrates a 60% improvement in sulfide electrolyte ion conductivity, 150% higher cell capacity and 90% reduced stacking pressure pre-tension force, the company said. Its safety has been validated through tests like nail penetration, crush test and thermal stability test. The company has also initiated road testing.

Gotion has recently introduced six new energy products. The lineup includes the GEMSTONE all-solid-state battery, which has entered the pre-production phase, the G-Yuan quasi-solid-state battery that has range of 1,000 kilometers, the G-Series batteries designed for 12-year use and a 20 MWh energy storage system.

The G-Yuan battery delivers 300 Wh/kg energy density, enabling EV ranges of over 1,000 km. Its adaptive solid-solid interface technology ensures stable ion transport. A 3 mm steel nail penetration test confirmed its safety. Gotion is currently building a 12 GWh production line and prototype vehicles are exceeding 10,000 km in road tests.

The G-series is a 116 kWh, high-capacity standard box for heavy-duty trucks, delivering 175 Wh/kg specific energy to support megawatt-level ultra-fast charging and -40° C to 65° C temperature control range. It shows zero capacity decay in the first 3,000 cycles, zero energy loss over 1.2 million kilometers of driving and an ultra-long cycle life of 12 years or 10,000 cycles, according to Gotion.

The Grid Q energy storage system delivers 20 MWh capacity per unit, backed by a 25-year design life. The modular design saves space while Air+Liquid cooling brings efficient thermal management.

The Astroinno Gen-2 lithium manganese iron phosphate (LMFP) battery realizes 10-minute ultra-fast charging, 240 Wh/kg specific energy and 93% cold-weather capacity retention at -20° C. The battery passes the thermal runaway test at the PACK level.
