Geely will begin vehicle testing of its self-developed solid-state battery starting this year. As reported by iFeng, the announcement was made by Geely Automobile Group CEO Gan Jiayue during a recent investor’s strategy conference, who said that the company’s first independently developed solid-state battery pack will be completed in 2026, and installed in rolling testbeds for validation testing.
The report did not specify which vehicle platform would be used for these trials, nor the company’s plans for future products equipped with the battery technology. Nevertheless, CarNewsChina reports that Geely has spent several years developing this technology in collaboration with high-voltage battery manufacturers. Its experimental cells have reportedly achieved an energy density of approximately 400 Wh/kg, and R&D teams are currently testing multiple electrolyte chemistries.
This milestone follows a decade of in-house battery R&D, including various joint ventures and production projects. A key precursor to this work was the 2024 release of the Aegis Short Blade lithium iron phosphate (LFP) battery, which marked the transition of Geely’s laboratory research into mass-market vehicle components.
As a next-generation technology, these solid-state batteries are more power-dense and lighter than traditional lithium-ion versions that use liquid or gel electrolytes. This higher density allows carmakers to offer the same capacity in a smaller package, resulting in lighter electric vehicles with increased range. Additionally, the absence of liquid electrolytes significantly reduces the risk of thermal runaway, making these vehicles inherently safer.

Geely is one of several carmakers making progress in solid-state technology. Recently, Hongqi officially moved its solid-state battery technology from the laboratory to real-vehicle testing, utilising a Hongqi Tiangong 06 as a test bed for its in-house developed pack.
Similarly, MG Motor recently began deliveries of the MG4 Anxin Edition in China, which is the world’s first mass-produced electric vehicle to feature a semi-solid-state battery. MG claims this new chemistry is not only safer, but also offers significantly improved performance and charging efficiency during extreme cold-weather conditions.
