At its 15th Global Technology Conference, Gotion High-Tech, backed by Volkswagen Group, unveiled its new sodium-ion battery brand, Gnascent. The company introduced three specialized cell variants and confirmed that gigawatt-hour-scale production facilities are already operational in Tangshan and Hefei.
The High-Energy version achieves an energy density of 261 Wh/kg—approximately a 60 percent improvement over conventional sodium-ion cells—and is targeted at weight-sensitive applications such as light electric vehicles and drones. The Power version offers 162 Wh/kg and supports ultra-low temperature discharge down to –50 °C, addressing cold-weather performance needs for commercial vehicles and outdoor equipment. The Energy Storage model features a single-cell capacity of 180 Ah, a cycle life exceeding 20,000 cycles, and maintains 88 percent capacity at –40 °C. It has passed rigorous safety protocols including an 8 mm steel nail penetration test and sustained 400 °C heating without ignition.
Gotion High-Tech aims to deploy Gnascent batteries across grid-side, industrial and residential energy storage systems, while also exploring niche markets such as two-wheelers and start-stop power supplies. The technological foundation of Gnascent rests on more than 90 patents, covering cathode materials—layered oxides, polyanions and sodium manganese iron pyrophosphate—along with hard carbon anodes and tailored electrolyte additives. An “anode-less” design further reduces material costs and boosts overall energy density.
Founded in 2006 and headquartered in Hefei, Gotion High-Tech has evolved into a vertically integrated global energy solutions provider, with Volkswagen as its largest shareholder. By the end of 2025, the company’s cumulative energy storage capacity reached 400 GWh, supported by 20 manufacturing bases worldwide. In April 2026, Gotion secured 6.6 percent of China’s power battery market with 4.05 GWh of installed capacity, ranking it third behind two leading domestic suppliers.
