- Svolt Energy plans to mass-produce hybrid solid-liquid batteries by September 2026.
- Hybrid solid-liquid batteries are expected to bridge the gap before all-solid-state battery commercialization.
Svolt Energy announced plans to begin mass production of its hybrid solid-liquid batteries by September 2026, marking a major milestone in the transition toward safer and more scalable battery technologies for electric vehicles. According to chairman and CEO Yang Hongxin, the new battery systems are expected to achieve production costs comparable to conventional liquid lithium-ion batteries while delivering significantly improved safety performance. The announcement was shared through a video published on Weibo, where Yang also highlighted the commercial importance of hybrid solid-liquid battery technology during the industry’s transition phase toward fully solid-state batteries.
The company believes hybrid solid-liquid batteries will become the dominant market solution before all-solid-state batteries achieve widespread commercialization. Yang stated that the industry still faces major technical and manufacturing barriers in the development of fully solid-state battery systems, making hybrid battery technology the most practical near-term option for large-scale deployment. He added that 2026 is expected to become the first major year for broad adoption of hybrid solid-liquid batteries, with increasing vehicle integration and large-scale market expansion anticipated across the automotive sector.
Under Svolt Energy’s commercialization roadmap, several vehicle models are expected to adopt the company’s hybrid solid-liquid batteries before the end of September. The company also plans to achieve large-scale production of its 100 kWh battery variant during the same period. These batteries combine liquid and solid electrolytes to transfer ions between the cathode and anode, offering a balance between performance, safety, and manufacturability. In recent years, the technology was widely referred to as semi-solid-state batteries, although the terminology in China has now been standardized as hybrid solid-liquid batteries to clearly distinguish them from all-solid-state systems.
Comparison Between Hybrid and All-Solid-State Batteries
| Battery Type | Electrolyte Structure | Commercial Readiness | Key Advantage |
|---|---|---|---|
| Hybrid Solid-Liquid Battery | Combination of liquid and solid electrolytes | Near-term mass production | Improved safety with scalable manufacturing |
| All-Solid-State Battery | Fully solid electrolytes | Still under development | Potential for higher energy density |
Industry leaders including CATL and BYD are also pursuing all-solid-state battery technology, with both companies targeting 2027 for small-scale production initiatives. Despite strong investment activity across the sector, many technical issues remain unresolved, including electrolyte stability, large-scale manufacturing consistency, and cost efficiency. As a result, hybrid solid-liquid batteries are increasingly being viewed as an intermediate technology capable of supporting electric vehicle growth until fully solid-state solutions mature commercially.
Svolt Energy originated as the power battery division of GWM and began battery research and development activities in 2012. The business was officially separated from GWM in February 2018 to concentrate on advanced battery materials, battery cells, modules, packs, battery management systems, and energy storage technologies. Since becoming independent, the company has expanded its focus toward next-generation electrification technologies aimed at improving battery safety, efficiency, and manufacturing scalability for global electric mobility applications.
According to data released by the China Automotive Battery Innovation Alliance, Svolt Energy recorded battery installations of 1.14 GWh during April, securing a 1.83% market share and ranking tenth within the Chinese battery market. CATL maintained its dominant market position with a 46.64% share, while BYD ranked second with 16.83%. The growing competition among battery manufacturers continues to accelerate technological innovation as companies race to strengthen their positions within the rapidly expanding electric vehicle supply chain.
Frequently Asked Questions
What are hybrid solid-liquid batteries?
Hybrid solid-liquid batteries use both liquid and solid electrolytes to transfer ions between battery electrodes, improving safety while maintaining practical manufacturing scalability. These batteries are considered an intermediate technology between traditional lithium-ion batteries and fully solid-state batteries. They are designed to offer better thermal stability, enhanced safety performance, and competitive production costs. Many automotive battery manufacturers are investing in hybrid solid-liquid battery technology because all-solid-state batteries still face technical and commercial challenges that could delay mass-market deployment for several years.
Why are hybrid solid-liquid batteries important for the EV industry?
Hybrid solid-liquid batteries are important because they provide a commercially viable path toward safer and more efficient electric vehicle batteries before all-solid-state systems become widely available. The technology allows manufacturers to improve battery safety and performance without completely overhauling existing production infrastructure. Industry leaders expect hybrid solid-liquid batteries to support large-scale EV adoption over the next several years as automakers continue seeking better energy storage solutions with improved scalability, reliability, and cost competitiveness across passenger vehicle segments.
