WPI researchers have developed a safer, scalable lithium-metal battery recycling method and a simplified solid-state battery design, tackling two of the most significant challenges in battery tech. A team from Worcester Polytechnic Institute (WPI), led by Professor Yan Wang, has published two significant studies to address critical challenges in lithium battery development. Safe and Scalable Lithium-Metal Battery RecyclingIn the Joule study, Wang’s team presents its safe, scalable, and cost-effective method for recycling highly reactive lithium-metal anodes.

This work establishes iron doping as an effective strategy to simplify solid-state battery design while enhancing stability and performance.
