Overview

GAC Group reconfirmed plans to integrate all-solid-state batteries with over 400 Wh/kg cell energy density into its Aion brand production vehicles by the second half of 2026, accelerating its entry into the next-generation EV market. Concurrently, CATL continues testing its condensed batteries in aircraft and premium EVs, pursuing higher performance. Toyota has also begun raw material input at its Japanese all-solid-state pilot line, aiming for integration into small-scale vehicles by 2027, with major manufacturers updating roadmaps and achieving concrete results in ASSB development and commercialization.

In Depth

Key Findings

Several leading automotive and battery manufacturers have updated their all-solid-state battery (ASSB) roadmaps and announced significant progress since July 2026. A notable highlight is GAC Group’s reaffirmation to integrate ASSBs with a cell energy density exceeding 400 Wh/kg into its Aion brand production vehicles by the second half of 2026. This marks a crucial indication that ASSBs are transitioning from limited testing phases to deployment in mass-produced vehicles.

Technical Details

The integration of ASSBs with an energy density exceeding 400 Wh/kg by GAC Group is set to dramatically enhance the range and performance of electric vehicles. This level of energy density surpasses that of current high-performance lithium-ion batteries (typically 250–300 Wh/kg), potentially transforming the EV user experience. Meanwhile, CATL, the world’s largest battery manufacturer, continues testing its condensed batteries in aviation and premium EV sectors, targeting applications that demand exceptionally high energy density and safety. Toyota is also steadily advancing its development, having initiated raw material input at its Japanese all-solid-state pilot line and aiming to integrate these next-generation batteries into small-scale vehicles by 2027. These developments showcase diverse strategies and paces adopted by companies in their pursuit of ASSB commercialization.

Background & Context

All-solid-state batteries are garnering immense anticipation from the automotive, aviation, and electronics industries as a technology capable of overcoming the safety issues (thermal runaway risk) and energy density limitations inherent in conventional lithium-ion batteries that use liquid electrolytes. The updated roadmaps and tangible progress announced by these companies strongly suggest that ASSBs, once considered a distant future technology, are now on the verge of practical implementation. GAC’s explicit commitment to integrate these batteries into production vehicles by a specific timeline is particularly significant, as it is expected to intensify market competition.

Strategic Significance & Outlook

GAC Group’s deployment of ASSBs in its Aion brand vehicles has the potential to accelerate the widespread adoption of all-solid-state batteries in the EV market. CATL’s continued testing in the aviation and premium EV sectors will pave the way for new high-performance battery applications and bolster technological credibility. Toyota’s plans will serve as a crucial indicator of Japan’s technological role in the global market. These advancements by major players collectively indicate that ASSB technology is poised to profoundly transform our lives and mobility in the near future.
