The Gnascent lineup’s specs are as follows: High-Energy Version: This cell achieves an energy density of 261 Wh/kg, a 60% increase over traditional sodium-ion batteries. This battery is specifically aimed at weight-sensitive applications such as light electric vehicles and drones within the “low-altitude economy.” Power Version: With an energy density of 162 Wh/kg, this version supports ultra-low temperature discharge down to -50°C. It is engineered to solve winter performance challenges for commercial vehicles and outdoor equipment in extremely cold regions. Energy Storage Version: Featuring a single-cell capacity of 180Ah, this version boasts a cycle life exceeding 20,000 cycles. It maintains 88% capacity at -40°C and has passed rigorous safety protocols, 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 exploring niche markets like two-wheelers and start-stop power supplies. The technological foundation of Gnascent is supported by over 90 patents covering cathode materials (layered oxides, polyanions, and sodium manganese iron pyrophosphate), hard carbon anodes, and electrolyte additives. Notably, the “anode-less” design helps reduce material costs while boosting energy density. Founded in 2006 and headquartered in Hefei, Gotion High-Tech has grown into a vertically integrated global energy solution provider with Volkswagen Group as its largest shareholder. By the end of 2025, the company’s energy storage capacity 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.
