Chery Solid-State Battery Timeline: 2027 Vehicle Validation

Chery Auto (HKEX: 9973) has outlined a new commercialization timeline for its Chery Auto solid-state battery technology, with vehicle validation of all-solid-state batteries planned for 2027. Chairman Yin Tongyue announced the timeline Thursday at the 2026 World Power Battery Conference in Yibin, Sichuan province. The company is developing multiple battery solutions through its Rhino Battery lineup, which covers hybrid vehicles, battery electric vehicles (BEVs), and solid-state applications. Chery's latest roadmap places a solid-liquid hybrid battery into vehicles in the fourth quarter of 2026 before its all-solid-state technology proceeds to vehicle validation the following year.

Chery Rhino Battery Advances Toward Vehicle Validation

The latest timeline broadly matches the roadmap Chery unveiled in March, when the company indicated that solid-liquid hybrid technology would be the first of its solid-state battery solutions to reach vehicle applications. Chery said its Rhino S series included a 60-Ah solid-state cell with an energy density of 400 Wh/kg. The cell uses a sulfide-based solid electrolyte and a high-nickel ternary cathode, representing one of Chery's principal technology routes toward commercializing all-solid-state batteries. The company is advancing several approaches in parallel as it works toward vehicle deployment while maintaining safety requirements as a condition for introducing any technology.

Solid-State Battery Energy Density Developments

Chery also demonstrated another solid-state battery technology in March, showcasing a polymer-based cell with an energy density of 600 Wh/kg. According to the company, the cell could support a vehicle range of more than 1,500 kilometers. These figures highlight the potential performance gains being targeted through solid-state battery development, while the company continues to evaluate different technical routes. The sulfide-based Rhino S cell and polymer-based technology therefore represent separate approaches within Chery's broader battery development strategy. Despite the reported energy-density gains, the transition from laboratory and development-stage cells to commercially produced vehicle batteries remains dependent on manufacturing and reliability considerations.

Mass Production Challenges Remain

Commercial-scale production of solid-state batteries continues to face challenges involving cost, reliability, and manufacturing yield. These issues remain important because high laboratory or prototype energy density does not by itself establish readiness for large-scale vehicle deployment. CATL (HKEX: 3750) chairman Robin Zeng said in June that, if solid-state battery technology progress were measured from level 1 to level 9, current development would be only at level 4, while level 9 would represent readiness for mass production. The assessment illustrates the gap that battery developers still need to close between technology development, vehicle validation, and dependable high-volume manufacturing.

Chinese Automakers Target 2026 and 2027 Battery Milestones

Chery's schedule is part of a broader push among Chinese automakers to bring all-solid-state batteries into vehicles during the second half of the decade. CATL and BYD (HKEX: 1211) are both targeting 2027 for small-volume deployment of all-solid-state batteries in vehicles. Geely Auto (HKEX: 0175) said in January that it planned to complete its first in-house developed all-solid-state battery pack in 2026 and conduct vehicle validation. Dongfeng Motor, meanwhile, plans to deliver 50,000 vehicles equipped with its in-house developed solid-state batteries in 2027. These targets indicate that vehicle validation and limited deployment are becoming key milestones before wider commercialization.

Safety Testing Remains a Core Requirement

Yin said Chery will advance multiple battery solutions in parallel, but no technology will be introduced into vehicles before meeting safety requirements. The Rhino Battery incorporates what Chery describes as a “360-degree safety protection system” and is expected to undergo testing under demanding conditions. These tests include high temperatures, extreme cold, crashes, underbody scraping, and water immersion. Such testing is intended to assess battery performance and protection across different operating and physical stress scenarios before vehicle applications proceed. The approach underscores that Chery's 2026 and 2027 milestones depend not only on energy density and technical development, but also on demonstrating safety under vehicle-level conditions.

Chery Expands Manufacturing Sustainability Efforts

Beyond battery development, Yin said green electricity accounts for more than 52% of the power used at Chery's manufacturing bases in China. He also said carbon-footprint accounting covers 100% of Chery's models currently on sale. These initiatives accompany the company's technology development as it prepares for continued expansion in electrified vehicles and international markets. The manufacturing figures provide an indication of Chery's efforts to address environmental considerations alongside battery technology. However, the company's immediate solid-state battery roadmap remains focused on progressing from the planned solid-liquid hybrid vehicle installation in the fourth quarter of 2026 to all-solid-state vehicle validation in 2027.

China's Auto Export Strategy Broadens

Yin expects China's automobile exports to exceed 10 million vehicles in 2026, with new energy vehicles (NEVs) accounting for more than half of total exports. He said the international expansion of Chinese automakers should not focus solely on short-term sales, but should instead emphasize localized operations and industrial cooperation. This strategy could influence how Chinese automotive companies approach overseas growth as electrified vehicle technologies continue to develop. For Chery, the global strategy sits alongside its domestic battery and manufacturing initiatives, creating a broader commercial context for the company's investment in next-generation battery technologies and vehicle platforms.

2026 World Power Battery Conference Highlights

The 2026 World Power Battery Conference is being held in Yibin, Sichuan province, from September 3 to September 4. Chery's announcement at the event places its solid-state battery roadmap within a wider industry discussion about battery technology, vehicle applications, safety, manufacturing, and commercialization. The company's stated schedule calls for its solid-liquid hybrid Rhino Battery solution to enter vehicles in the fourth quarter of 2026, followed by vehicle validation of the all-solid-state battery in 2027. Whether these technologies progress beyond validation toward larger-scale deployment will depend on safety performance, manufacturing yield, reliability, and cost as development advances.

Frequently Asked Questions

When will Chery begin vehicle validation of its all-solid-state battery?
Chery plans to begin vehicle validation of its all-solid-state battery technology in 2027, following the planned installation of a solid-liquid hybrid battery in vehicles during the fourth quarter of 2026. The company has developed a Rhino Battery lineup covering hybrid, battery electric, and solid-state applications, with its Rhino S solid-state cell reported at 400 Wh/kg. Chery has also demonstrated a polymer-based solid-state cell reaching 600 Wh/kg, but commercialization remains subject to safety, reliability, cost, and manufacturing-yield requirements before broader vehicle deployment.
