On June 9, GEM disclosed that it has signed a cooperation agreement to jointly establish a joint laboratory for solid-state battery cathode materials and to conduct collaborative research on key technologies for the industrialization of solid-state lithium battery cathode materials. GEM plans to invest a total of 30 million yuan into the joint laboratory over five years. Of this amount, 20 million yuan will be used for the construction and operation of the joint laboratory, while the remaining 10 million yuan will be allocated for the pilot-scale conversion of laboratory technologies once they mature. The funds for the joint laboratory will be managed under a separate account at Ningbo Eastern University of Technology, earmarked exclusively for research and development activities within the joint laboratory.

According to EV media outlet Electrek on June 4 local time, Nissan is launching a project to develop “Cost-effective, Resilient Solid-state Li-S” batteries together with UK battery company Gelion, Nissan Technical Centre Europe (NTCE) and the University of Oxford. The project will run for three years, with a total budget of around GBP 3.4 million, or about USD 4.5 million. Of this, Gelion will receive around GBP 2.4 million, or about USD 3.2 million, in UK government funding. The key focus of the project is the development of solid-state lithium-sulfur batteries using sulfur-based cathode materials.

Material Prices: Most solid-state battery materials declined. LPSC dropped 5.5% to RMB 7,280/kg, Li₂S fell 3.8% to RMB 1,530/kg, Li metal and LFP fell 1.7% and 1.4% respectively. Only P₂S₅ rose 2.6%. Oxide electrolytes (LATP, LLZO) were flat.

[SMM Magnesium Survey: Japan Achieves Breakthrough in Magnesium Battery Technology, Romania Launches Low-Carbon Magnesium Project] Tohoku University in Japan developed a magnesium-tin alloy anode, boosting the cycle life of solid-state magnesium batteries by over 400 times and overturning the traditional concept of interfacial reaction suppression. Romania's Verde Magnesium launched an EU strategic flagship project, adopting a low-carbon aluminothermic smelting process, and plans to build a 30,000 mt/year smelter by 2030, filling the 25-year gap in primary magnesium production in Europe and creating a near-zero-carbon magnesium supply chain.

​​​​​​​Industrialization accelerated sharply in May: SAIC MG 4X launched with a semi-solid battery (53.9kWh, 510km range). Gotion Hi-Tech unveiled its “Jinshi” all-solid-state battery (400Wh/kg) aiming for 1 yuan/Wh cost by 2030. Qingtao Energy’s 5-billion-yuan, 20GWh project advanced. MIIT started solid-state battery standards.

CIBF2026 Solid-State Battery Recap: It’s Complicated – Everyone Is Moving Toward Solid-State, but Everyone Is Still Testing the Waters May 13–15, 2026 – The solid-state battery exhibition revealed that solid-state has become a "must-have" for exhibitors. However, technology paths (sulfide/oxide/semi-solid) remain deeply divided, the definition of "mass production" has been diluted, and most products are still in the sample-validation stage.

[SMM]Gotion High-Tech today unveiled its latest solid-state battery developments at the company's 15th Global Technology Conference. Following upgrades to its cell technology, the energy density has reached 400 Wh/kg. The company's 2 GWh solid-state battery mass production line is currently under construction, with customers across multiple application scenarios already engaged. According to the roadmap, Gotion High-Tech's annual lithium sulfide production capacity is planned at 300 tonnes this year, scaling to 20,000 tonnes by 2027 and 50,000 tonnes by 2030, in order to meet the demand for 150 GWh of solid-state batteries.

On May 16, Tianli Lithium Energy disclosed that its high-nickel 9-series products, which are compatible with solid-state battery technology routes, have achieved mass shipments. These products possess strong industry competitiveness in aspects such as energy density, cycle stability, and solid-state interface compatibility. The company is actively cooperating with multiple customers to continuously deepen its business relationships.

POSCO Future M recently signed an exclusive development agreement with a Japanese automaker for cathode materials used in all-solid-state batteries, according to industry sources on May 5. Under the deal, POSCO Future M will exclusively develop and supply cathode materials for the automaker’s all-solid-state battery project. The partner is reportedly a mid-sized carmaker. This marks the first case in which a Japanese automaker has designated a Korean materials company as the sole supplier of cathode materials for all-solid-state batteries.
