Solid-State Batteries: Changan to Launch in 2026, 1500km Range Possible

The long-awaited arrival of solid-state batteries appears to be accelerating, with Chinese manufacturers leading the charge. While solid-state battery technology has been touted as a potential game-changer for electric vehicles for years, practical implementation has lagged. Now, Changan, a major Chinese automaker, plans to begin incorporating its fresh solid-state batteries into both robots and electric vehicles in the third quarter of this year, with full-scale mass production slated for 2027. Electrive.com reports on this development.

Chinese media outlets are reporting that Changan’s new solid-state battery boasts an energy density of 400 Wh/kg. This level of density, if realized, would translate to an electric vehicle range exceeding 1,500 kilometers (approximately 932 miles) on a single charge. While this figure appears ambitious, even a partial achievement of this range would significantly enhance the practicality of EVs, particularly for long-distance travel in regions with limited charging infrastructure. Electrek highlights the potential for extended range with these new batteries.

The battery, internally dubbed “Golden Bell,” is claimed to be 70% safer than conventional EV batteries, alongside utilizing artificial intelligence for remote diagnostics – a feature reflecting the current technological landscape of 2026. Changan intends to manufacture these devices under its new solid-state battery brand, Jingzhongzhao. The company’s strategy involves producing fully solid-state battery packs while simultaneously continuing production of liquid and semi-solid batteries, which rely on liquid electrolytes.

Changan isn’t alone in this pursuit. Dongfeng Motor has as well been actively testing its own solid-state battery technology in extreme cold weather conditions. Their battery achieves an energy density of 350 Wh/kg and a claimed range exceeding 1,000 km (621 miles), with plans for implementation in production vehicles this year, targeting a September rollout. Carscoops details Dongfeng’s progress.

Other major Chinese automotive brands, including BYD, Chery, SAIC and GAC, as well as battery manufacturer CATL, are all actively working towards similar breakthroughs. The interest isn’t limited to Chinese companies; global automakers like Mercedes-Benz, Volkswagen, BMW, Toyota, Nissan, Hyundai, and Honda are also heavily invested in solid-state battery research and development. After years of promising headlines and laboratory successes, solid-state batteries may finally be on the verge of becoming a commercial reality.

The Competitive Landscape and Potential Impact

The push for solid-state batteries is driven by several key advantages over traditional lithium-ion technology. These include higher energy density (leading to longer range), improved safety (reduced risk of thermal runaway and fires), and potentially faster charging times. The race to commercialize this technology is particularly intense in China, where the government has been actively promoting the development of electric vehicles and battery technology. This support, combined with a robust supply chain and a large domestic market, has positioned Chinese companies at the forefront of the solid-state battery revolution.

The potential impact on the automotive industry is significant. If solid-state batteries deliver on their promises, they could alleviate range anxiety, a major barrier to EV adoption. Faster charging times would also make EVs more convenient for consumers. The increased safety of solid-state batteries could address concerns about the potential for fires, further boosting consumer confidence. This could accelerate the transition away from internal combustion engine vehicles, with profound implications for the oil industry and related sectors.

Financial Implications and Investment

The development and deployment of solid-state battery technology require substantial investment. Companies are pouring billions of dollars into research and development, as well as building new manufacturing facilities. Changan’s investment in its Jingzhongzhao brand and production facilities is a prime example. The cost of producing solid-state batteries is currently higher than that of lithium-ion batteries, but as production scales up and manufacturing processes are optimized, costs are expected to decline. This cost reduction will be crucial for making solid-state batteries competitive in the mass market.

The potential for high returns is attracting significant investor interest. Venture capital firms and strategic investors are pouring money into solid-state battery startups and established companies alike. The success of these investments will depend on the ability of companies to overcome technical challenges, scale up production, and reduce costs. The companies that can successfully navigate these hurdles are poised to capture a significant share of the rapidly growing EV battery market.

Risks and Challenges Remain

Despite the recent progress, several challenges remain before solid-state batteries can turn into widely adopted. One key challenge is scaling up production. Manufacturing solid-state batteries is more complex than manufacturing lithium-ion batteries, and requires specialized equipment and expertise. Another challenge is ensuring the long-term durability and reliability of solid-state batteries. The solid electrolyte material must be able to withstand repeated charge-discharge cycles without degrading. Finally, the cost of solid-state batteries remains a significant barrier to adoption. Reducing the cost of materials and manufacturing processes will be crucial for making solid-state batteries competitive with lithium-ion batteries.

What to Expect in the Coming Months

The next few months will be critical for the development of solid-state battery technology. Changan’s rollout of its solid-state batteries in the third quarter of this year will be a key milestone. Investors and industry observers will be closely watching to see how the batteries perform in real-world conditions. Dongfeng Motor’s planned implementation in September will also be closely monitored. Further announcements from other Chinese automakers and global players are expected as the race to commercialize solid-state batteries intensifies. The coming year will likely reveal whether these ambitious claims translate into a tangible shift in the EV landscape.
