Geely has confirmed a development milestone for its self-developed all-solid-state battery, stating that the first complete battery Pack will be finished in 2026 and will then undergo vehicle installation and validation. The disclosure provides a timeline for Geely’s in-house solid-state battery project at a vehicle-level verification stage rather than laboratory research.
The information was reported by 21 Finance on January 22, citing confirmation from Geely. According to that report, the 2026 milestone includes completing the first Pack assembly and installing it into a vehicle for validation testing. Geely did not disclose which vehicle platform will be used for this testing, nor did it provide a schedule for subsequent testing stages or production planning.
Geely has been developing battery technology in-house since the mid-2010s, including joint ventures, R&D facilities, and early production projects. In 2025, the company consolidated multiple battery initiatives under a single entity, Zhejiang Jiyao Tongxing Energy Technology, to integrate battery cell production and safety system development, and developed the Aegis Short Blade lithium iron phosphate battery, a self-produced LFP cell, preparing 20 ampere-hour engineering samples. The company also shared its battery safety patent portfolio with other automakers and invested in a safety testing facility in Ningbo, China, for vehicle validation.
Geely has been researching solid-state battery technology for several years, focusing on cell chemistry, solid electrolytes, and integration methods. The company has established dedicated research units and a Solid-State Battery Joint Laboratory in Zhejiang, collaborating with power battery manufacturers to advance core technologies. Experimental cells have reportedly reached energy densities of around 400 Wh/kg, and multiple electrolyte chemistries, including sulfide and oxide-based approaches, are being explored. Geely’s work is supported by national programs promoting next-generation EV batteries, situating the 2026 Pack completion and vehicle installation validation within a broader, multi-year R&D effort.
Solid-state batteries use a solid electrolyte rather than the liquid electrolyte used in conventional lithium-ion batteries. Within China’s automotive industry, development of these systems is reported to be progressing from laboratory research toward Pack assembly, vehicle installation validation, and pilot or small-batch production. Industry sources indicate that Chinese manufacturers and battery suppliers are advancing solid-state technology in line with national industrial priorities for electric vehicle innovation.
Other Chinese automakers and battery developers are pursuing solid-state projects with varied timelines. Dongfeng has adjusted its mass-production target for its solid-state batteries to 2027, with prototype vehicles already being tested and energy density goals around 350 watt-hours per kilogram. SAIC Motor’s partner Qingtao Energy has achieved full-line commissioning on a dedicated production line and plans prototype testing, followed by mass delivery in 2027, with technical targets including cells with energy density above 400 watt-hours per kilogram. Chery has produced engineering samples at its solid-state battery production facility. Battery suppliers such as Sunwoda have announced pilot-scale development of solid-state cells with materials partners.
National industrial guidance designates 2026 as a year to accelerate innovation in strategic electric vehicle technologies, including solid-state batteries and advanced autonomous driving, with companies such as Dongfeng, Chery, Sunwoda, and SAIC planning prototype deployment, scaled production, and energy-dense cell research in the coming years.
The report confirms that Geely’s solid-state battery project will reach Pack completion and vehicle-installation validation in 2026, placing it among the vehicle-level validation efforts in China’s emerging solid-state battery sector. It follows the company’s 2025 in-house battery development activities.
