Svolt Chief Labels Finnish Solid-State Battery Claims a Fraud

Reporters say Donut Lab has not provided independent test data or shown production facilities.

Mit dieser Batterie will das finnische StartUp „Donut Lab" den Elektro-Automarkt umkrempeln. Das Unternehmen wirbt mit niedrigen Kosten.
Der Chery Liefeng soll als erstes Modell die neue „Nashorn“-Feststoffbatterie erhalten.

Overview

  • Donut Lab unveiled what it called a series-ready solid-state cell at CES 2026, touting roughly 400 Wh/kg energy density, 100,000 cycles, and an 80 percent charge in under five minutes at low cost.
  • Svolt CEO Yang Hongxin told Chinese media the stated parameters contradict each other and argued such a battery does not exist, calling the announcement a fraud.
  • Coverage notes Donut Lab has withheld key technical details and has not presented evidence of pilot manufacturing or prototype production equipment.
  • Svolt says it is producing semi-solid batteries on a 2.3 GWh line with about 188 Wh/kg at system level and fast charging up to 6C, while major suppliers such as CATL and BYD point to limited vehicle integrations from 2027.
  • Separately, Chery promotes a 'Rhino S' solid-state cell claiming up to 600 Wh/kg and plans fleet trials in 2026 with broader use in 2027, though experts still expect wider solid-state adoption closer to 2030.
