Dramatically longer-lasting, faster-charging and safer lithium metal batteries may be possible, according to Penn State research, recently published in Nature Energy. The researchers developed a 3D cross-linked polymer sponge that attaches to the metal plating of a battery anode.

“This project aims to develop the next generation of metal batteries,” said Donghai Wang, professor of mechanical engineering and the principal investigator of the project. “Lithium metal has been tried in batteries for decades, but there are some fundamental issues that inhibit their advancement.”

Under additional strain, like in the fa...
