penghui energy's "heavyweight" achievements
first, penghui energy announced a major breakthrough in all-solid-state batteries on august 21. this technological breakthrough refocused the market's attention on solid-state batteries, and it released its first generation of solid-state batteries on august 28. penghui energy said that its core advantages lie in safety and cost reduction. it uses innovative electrolyte wet coating to solve the preparation process problems of oxide electrolytes, and the overall cost is expected to be only 15% higher than traditional lithium batteries.
in addition, penghui energy also stated that the energy density of the solid-state battery is 280wh/kg, and the energy density will reach more than 300wh/kg by 2025 when silicon-based negative electrode materials are used. it is planned to start pilot research and development and small-scale production in 2025, and to officially establish a production line and mass production in 2026.
breakthrough results from the chinese academy of sciences
at the same time, the qingdao institute of bioenergy and process technology of the chinese academy of sciences announced on its official wechat account that it has made important progress in the high-capacity cathode materials of sulfide all-solid-state batteries. the high-energy-density, long-cycle all-solid-state lithium-sulfur battery based on lithium sulfide cathode developed by the institute has an energy density of more than 600wh/kg, which is more than 1 times higher than that of commercial lithium-ion batteries.
this shows that pure sulfide positive electrode materials can effectively reduce costs and solve the problem of high cost of consistent lithium battery positive electrode materials.
market opportunities and challenges
solid-state battery technology is constantly innovating, and market opportunities and challenges coexist. from technological breakthroughs to market opportunities, the field of solid-state batteries is in a rapid development stage, and the future market potential is huge.
