Internet Info Agency China

Overview

In the first half of 2024 (as referenced, despite the article date), multiple Chinese automakers, including SAIC Motor with its MG4 ‘Semi-Solid-State Peace-of-Mind Edition’ and NIO with its 150kWh semi-solid battery pack, launched or announced semi-solid-state battery (SSB) EVs. Chery and GAC Group also plan to adopt SSBs within the year. Driven by this demand, battery manufacturers CALB and SVOLT are set to begin mass production of SSBs in the second half of 2026, accelerating the commercialization of semi-solid technology in the battery industry.

In Depth

Key Findings

In a significant development for the Chinese automotive market, major automakers such as SAIC Motor, NIO, Chery, and GAC Group have successively launched or announced plans for electric vehicles (EVs) equipped with semi-solid-state batteries (SSBs). Responding to this demand, leading battery suppliers CALB and SVOLT are scheduled to commence mass production of SSBs in the second half of 2026, marking a rapid advancement in the commercialization of semi-solid battery technology.

Technical & Clinical Details

• In the first half of 2024 (referencing the period of events, despite the article’s publication date of June 11, 2026), SAIC Motor introduced its ‘MG4 Semi-Solid-State Peace-of-Mind Edition,’ while NIO unveiled models featuring a 150kWh semi-solid-state battery pack. These vehicles demonstrate enhanced energy density, improved safety, and superior low-temperature performance compared to conventional liquid-electrolyte lithium-ion batteries.
• Chery and GAC Group have also declared their intentions to adopt semi-solid-state batteries in their vehicles within the current year, which is expected to further expand the range of SSB-equipped EVs available in the market.
• Driven by robust demand from these automakers, CALB and SVOLT are committed to establishing full-scale mass production capabilities for semi-solid-state batteries starting in the second half of 2026. This indicates the maturation of the SSB supply chain and the prospect of stable supply.

Background & Context

Semi-solid-state batteries have garnered considerable attention as an intermediate technology bridging the gap towards full solid-state batteries. They offer higher energy density and improved safety profiles compared to existing lithium-ion batteries, without requiring the extreme manufacturing complexities of full solid-state solutions, thus enabling earlier commercialization. Particularly in China, with its rapidly expanding new energy vehicle (NEV) market, battery technology innovation is crucial for bolstering competitive advantage. The close collaboration between automakers and battery suppliers is significantly accelerating the practical application of this technology.

Strategic Significance & Outlook

The market introduction of SSB EVs by multiple automakers, followed by battery suppliers’ mass production plans, suggests that semi-solid-state batteries are likely to establish themselves as a mainstream technology in the EV market. This development will allow consumers to consider EVs with extended range and enhanced safety as more accessible options. Furthermore, the mass production of SSBs is expected to further optimize manufacturing costs and lay a foundational pathway for a smoother technological transition to full solid-state batteries. This represents a significant trend that will contribute substantially to the overall development of the EV market and the wider adoption of next-generation battery technologies.
