It is also reported that FinDreams may have chosen the technical route of nickel-rich nickle-manganese-cobalt cathode (single crystal) + silicon-based anode (low expansion) + sulfide electrolyte (composite halide), with a solid-state cell capacity of over 60Ah, a mass-specific energy density of 400Wh/kg, and a volume-specific energy density of 800Wh/L.

Furthermore, in the field of battery materials, the lithium mining giant Tianqi Lithium announced that it has completed the industrial preparation of the next-generation solid-state battery key raw material lithium sulfide, and has conducted sample tests with more than ten downstream customers. BASF-Shanshan Battery Materials Company launched the cathode active material for all-solid-state batteries and recently completed pilot-scale production at its Changsha base. In addition, the Qingdao Institute of Bioenergy and Process Technology of the Chinese Academy of Sciences has developed a new type of lithium sulfide cathode material for all-solid-state lithium-sulfur batteries, with an energy density exceeding 600Wh/kg. Compared to the currently commercialized lithium-ion batteries, its energy density is more than double, and the cost is lower.

On September 11, Mercedes-Benz and the American startup battery company Factorial Energy announced that they will jointly develop a new type of solid-state battery named “Solstice.” This battery technology is expected to reduce the weight of the battery by 40% and increase the driving range of electric vehicles by 80%, with an expected cruising range of up to 1000 kilometers, aiming to achieve mass production by 2030. On July 11, Volkswagen Group’s battery company PowerCo and the American startup QuantumScape reached an agreement to jointly promote the industrialization of QuantumScape’s next-generation solid-state lithium metal battery technology.
