[Solid-state battery: Doubts over GHTECH's claim of launching lithium sulfide products to market] On October 16, 2026, GHTECH (002741.SZ) stated on the Shenzhen Stock Exchange's Easy Interaction platform, in response to an investor's question about "whether lithium sulfide has begun small-batch production and supply," that its lithium sulfide products have been launched to the market, with capacity, validation, and orders progressing steadily as planned. Revenue in the first three quarters reached 3.575 billion yuan, up 74.89% YoY; net profit attributable to the parent company was 129 million yuan, up 42.29% YoY; and net profit excluding non-recurring items was 124 million yuan, up 40.44% YoY. However, SMM has not yet identified which electrolyte enterprises are using GHTECH's lithium sulfide products.

[Solid-State Battery: CAS Dongguan Institute of Materials Develops Oxychloride Solid Electrolyte LAGCO with Estimated Raw Material Cost of $40.8/kg] On October 8, 2026, a research team led by Researcher Liu Lifeng from the Dongguan Institute of Materials Science and Technology, Chinese Academy of Sciences / Songshan Lake Materials Laboratory, in collaboration with teams from Hunan University and the Institute of Physics, CAS, developed a crystalline-amorphous heterostructure oxychloride solid electrolyte LiAl₀.₅Ga₀.₅Cl₂.₅O₀.₇₅ (LAGCO). This system reduces reliance on expensive rare-metal halides, with an estimated raw material cost of approximately $40.8/kg, achieving a synergy of fast ion transport and stable interfaces in the oxychloride solid electrolyte direction. SMM believes that lithium aluminum gallium chloride oxide (LAGCO) combines fast ion transport with stable interfaces, reduces dependence on rare metals, and has a raw material cost of approximately $40.8/kg, offering a new pathway for low-cost oxychloride solid electrolytes. However, its performance compatibility and mass-production consistency still require verification.
