Gotion High-Tech, a leading Chinese battery maker backed by VW, officially launched its dedicated sodium-ion battery brand Gnascent at its 15th Global Technology Conference, where it introduced three specialized versions of the battery.
Gotion said that it has already established gigawatt-hour (GWh) scale production lines for these products in Tangshan and Hefei in mainland China.
The Gnascent lineup includes a high-energy version with an energy density of 261 Wh/kg, which represents a 60% increase over traditional sodium-ion batteries and is aimed at weight-sensitive applications such as light electric vehicles (EVs) and drones in the low-altitude economy.
The power version has an energy density of 162 Wh/kg and supports ultra-low temperature discharge down to -50°C, targeting winter performance challenges for commercial vehicles and outdoor equipment in extremely cold regions.
The energy storage version features a single-cell capacity of 180Ah, a cycle life exceeding 20,000 cycles, maintains 88% capacity at -40°C, and has passed safety tests including an 8mm steel nail penetration test and 400°C high-temperature heating without ignition.
Gotion High-Tech's strategic goal for Gnascent is to achieve large-scale application in grid-side, industrial, and residential energy storage, while also exploring niche markets such as two-wheelers and start-stop power supplies. Gnascent's technological foundation is supported by over 90 patents covering cathode materials, including layered oxides, polyanions, and sodium manganese iron pyrophosphate, as well as hard carbon anodes and electrolyte additives. An anode-less design is noted for helping to reduce material costs while boosting energy density.
Founded in 2006 and headquartered in Hefei, Gotion High-Tech has developed into a vertically integrated global energy solution provider with VW Group as its largest shareholder. By the end of 2025, the company's energy storage capacity had reached 400 GWh, supported by 20 manufacturing bases worldwide.
In China, Gotion High-Tech is the leading power battery supplier after CATL and BYD last month. In April, its installed battery capacity reached 4.05GWh, accounting for a 6.6% market share. As sodium-ion technology matures, Gotion High-Tech joins other industry giants, including CATL and BYD, in accelerating the deployment of sodium-based solutions.
