[Solid-State Battery: Purdue University Research Reveals Formation Mechanism of Interfacial Defects in Solid-State Batteries, Wins Engineering Research Award] On September 14, 2026, a research team from Purdue University's College of Engineering used computer modeling to reveal the formation mechanism of interfacial defects in solid-state batteries. The study provides guidance for safer, higher-energy-density lithium and sodium-ion batteries and received an engineering research award.

Estone Materials Technology disclosed on Sept 15 a plan to raise up to RMB 400 million via a private A-share placement for an 8,000 t/yr boehmite project for ultra-thin lithium battery separator coating, a 20,000 t/yr high-purity quartz sand phase II project, and working capital. The boehmite project, with total investment of about RMB 102 million and a 12-month construction period, will build new small-particle-size boehmite lines that reduce separator coating thickness below 1 micrometer, boosting cell energy density and electrolyte wettability for high-voltage fast-charging power batteries and high-safety energy storage batteries, further consolidating its global leading position in boehmite coating materials.
