- Svolt has completed development of its first-generation semi-solid-state square battery cells with an energy density of 270 Wh/kg.
- Svolt is currently developing its second-generation semi-solid-state battery cells with an energy density of 400 Wh/kg.
Svolt Energy plans to commence volume deliveries of its first-generation semi-solid-state batteries next year, becoming the latest Chinese company with such plans.
In 2026, Svolt's first-generation semi-solid-state batteries will enter mass production and achieve volume deliveries, Yang Hongxin, chairman and CEO of the battery manufacturer, said at the 2025 World Power Battery Conference on November 12.
The company has completed development of its first-generation semi-solid-state square cells with an energy density of 270 Wh/kg, which will soon enter C-sample batch trial production, Yang said, according to Svolt's publicly released presentation on November 15.
The product has secured orders from a renowned European electric vehicle (EV) brand and will power an electric vertical takeoff and landing (eVTOL) project for a Chinese state-owned enterprise, he added.
Svolt has established a dedicated semi-solid-state battery production line with a capacity of 2.3 GWh, Yang said.
The company is currently developing second-generation semi-solid-state battery cells with an energy density of 400 Wh/kg, he said.
By 2028, Svolt will complete the development of semi-solid-state pouch cells with an energy density of 450 Wh/kg, according to Yang.
Ternary lithium batteries remain the preferred choice for high-end EVs and emerging market segments, but they account for up to 70 percent of EV fires caused by thermal runaway, he noted.
Svolt addresses ternary lithium's thermal stability issues with its semi-solid-state technologies. By introducing non-flammable, non-corrosive solid electrolytes, the company enhances safety without sacrificing performance or increasing manufacturing costs, Yang explained.
In July, local media outlet Cailian cited Yang as saying Svolt would commence trial production of its first-generation semi-solid-state battery with a capacity of 140 Ah in the fourth quarter.
The semi-solid-state battery would be supplied to the next-generation models of BMW's sub-brand Mini, with mass supply planned for 2027, the report said.
Also at the 2025 World Power Battery Conference, Dongfeng Motor (HKG: 0489) said it expected to begin mass production of solid-state batteries with an energy density of 350 Wh/kg for vehicle integration in September 2026, enabling a driving range of 1,000 kilometers.
Dongfeng has constructed and commissioned a 0.2 GWh pilot production line for solid-state batteries, it announced.
Svolt, spun off from GWM (HKG: 2333) in February 2018, primarily focuses on battery materials, cells, modules, packs, BMS, and energy storage technologies.
It ranks as one of China's largest battery manufacturers, with October battery installations reaching 2.27 GWh, securing a 2.71 percent market share and placing seventh in the domestic power battery market, according to data from the China Automotive Battery Innovation Alliance (CABIA).
