the global titanium resource reserves are mainly based on tio2. china has the second largest production capacity in the world, accounting for 29% of the global market share. enterprises such as china national nuclear titanium dioxide and longbai group dominate china's titanium dioxide industry, and their output and technical level maintain a high level of international competitiveness.

as a new type of solid-state battery material, sulfide electrolyte has broad application prospects. the core is lithium sulfide, the synthesis of which requires special process conditions and costs, making the market price high. at present, preparation methods such as mechanical ball milling, high-temperature reduction and solvent methods all have high requirements for temperature, moisture and energy consumption, and need to be carried out in an inert atmosphere, resulting in high costs.

in addition, sulfide electrolytes also face problems such as poor solid-solid interface contact, reduced ion transfer efficiency, and easy reaction with moisture to produce toxic gases. these problems need to be further resolved.

in this context, some companies have begun to actively deploy lithium sulfide preparation technology in order to reduce costs and ultimately promote the popularization and development of all-solid-state battery technology. tianqi lithium has brought new hope to the lithium sulfide market through related support work for the industrialization of next-generation lithium sulfide, proofing with more than ten downstream customers, and continuous product quality improvement and cost reduction technology optimization. hunan enjie frontier new materials, a holding subsidiary of enjie co., ltd., has completed the construction and operation of a small-scale annual production capacity of tonnes, and built a pilot production line of 100 tons of lithium sulfide, providing a solid foundation for the popularization of all-solid-state battery technology. rongbai technology has reduced the cost of lithium sulfide by improving the method of adding organic sulfur sources. through breakthroughs in material modification, blue ocean huateng has the ability to mass-produce tons of lithium sulfide raw materials under the premise of controllable costs, and has achieved impressive material purity and ionic conductivity performance test results.

in the future, as the research and development and application of all-solid-state battery technology continue to deepen, sulfide electrolytes will usher in a new development opportunity, and companies that make early arrangements will benefit from this opportunity.
