Improving lithium metal batteries

A Spartan engineer at Michigan State University is part of a national research team that has determined the proper stack pressure that lithium metal batteries, or LMBs, need for optimal performance during battery operation.

Chengcheng Fang, an assistant professor in the MSU Department of Chemical Engineering and Materials Science, is the first author on the research that was published Oct. 18, 2021, in Nature Energy.

Fang said that by exploring the stack pressure effect on the electrochemical behavior of LMBs, the work achieved fully dense and reversible lithium metal anode.

“The precise manipulation of lithium deposition and dissolution is a critical step to enable practical lithium metal batteries, which doubles the energy density of today's lithium-ion technology,” she explained.
