[Solid-state: FAW Reports Low-pressure Sulfide Battery Breakthrough; Li2S Pilot Lines Advance]

On the raw material, material, and cell sides, leading companies quietly made continuous breakthroughs in R&D and technology iteration, while startups increased external promotion efforts to build sufficient customer reserves before the commercialization wave of solid-state batteries arrives. The Ministry of Industry and Information Technology (MIIT) and the National Development and Reform Commission (NDRC) issued the 15th Five-Year Plan for the Electronic Information Manufacturing Industry.

[Solid-state battery: Highpower Technology deploys three solid-state routes of polymer/oxide/sulphide, with multiple solid-state electrolyte patents granted] On September 17, 2026, Highpower Technology disclosed its solid-state battery layout during an institutional survey. The company is simultaneously developing three major solid-state electrolyte technology routes: polymer, oxide, and sulphide. In 2026, it has filed four core solid-state battery patents, covering composite solid-state electrolytes, solid-state electrolyte membranes, and gel polymer electrolytes, with a focus on solid-state battery development for I-end devices and robotics scenarios.

[Solid-state battery: Easpring Technology's sulphide electrolyte enters the small-scale test validation stage with leading clients] On 16 September 2026, Easpring Technology stated on an investor interaction platform that the company has prepared highly active and highly dispersed lithium sulphide and nano-sulphide electrolyte precursors through special production processes such as particle size control, establishing an integrated preparation chain from "lithium sulphide – highly active sulphide electrolyte precursor – high performance sulphide electrolyte". Currently, the sulphide electrolyte materials synthesised from the company's self-developed lithium sulphide and precursors have entered the small-scale test validation stage with leading solid-state battery clients.
