Svolt Fortress 2.0: 80kWh battery for hybrid cars charges in 10 minutes, semi-solid-state battery debuts

New charging technology and solid-state batteries

In addition to the new hardware, the company further unveiled a new charging method. The latest generation of the so-called Ion Oscillation Pulse Charging technology is intended to decrease charging times by 25% without increasing costs. This technology is set to be used in initial electric vehicles starting in the third quarter of 2026.

Svolt has also reported progress in its development of semi-solid-state batteries. The first generation of its semi-solid-state batteries with an energy density of 270Wh/kg is already being produced in small quantities and could be featured in a car from a European brand, which probably refers to BMW-owned Mini. Back in October 2025, Svolt officially confirmed that it was developing customized energy solutions for the brand. A second generation with even higher density at 342 Wh/kg was developed specifically for eVTOL and has already been successfully tested in flight trials.

For the mass market, Svolt plans to start production of a more affordable mid-nickel variant with 245 Wh/kg in October 2026. Thanks to a new electrolyte transfer technology, these cells are said to be particularly resistant to thermal runaway. From a business perspective, this approach appears to be working, as Svolt posted its first quarterly profit in the fourth quarter of 2025 and is aiming for profitability for the full year 2026.
