Svolt Energy plans to begin mass production of hybrid solid-liquid batteries by September, with the company expecting production costs to reach levels comparable to conventional liquid lithium-ion batteries.
The company’s chairman and chief executive, Yang Hongxin, disclosed the plan in a video shared on Weibo on Tuesday, saying the new battery technology offers significantly improved safety performance compared with traditional battery systems.
Yang said hybrid solid-liquid batteries are expected to become the dominant transitional technology before all-solid-state batteries can be commercially produced at large scale, adding that 2026 could mark the beginning of broader adoption and commercialization for the technology.
Under Svolt’s roadmap, multiple vehicle models are expected to adopt the new batteries by the end of September, when the company also plans to begin large-scale production of a 100-kWh battery version.
Hybrid solid-liquid batteries, commonly referred to in recent years as semi-solid-state batteries, use both liquid and solid electrolytes to transfer ions between the cathode and anode. By comparison, all-solid-state batteries rely entirely on solid electrolytes.
Chinese industry participants have increasingly adopted the term “hybrid solid-liquid batteries” to distinguish the technology from fully solid-state batteries and avoid confusion among consumers.
The battery sector continues to face major technical challenges in the commercialization of all-solid-state batteries. Industry leaders including CATL and BYD are targeting 2027 for initial small-scale production of fully solid-state battery technologies.
Svolt Energy was originally established as the battery division of GWM and began battery research and development in 2012 before becoming an independent company in 2018.
The company currently focuses on battery materials, cells, modules, battery packs, battery management systems and energy storage technologies.
