DOE researchers increase lithium-sulfur battery performance using silica cathodes

Thu, 09/10/2020 - 10:14 -- Paul Crompton

Researchers at U.S. Department of Energy’s (DOE) Argonne National Laboratory have found a polar, nonconductive cathode can increase the performance of lithium-sulfur batteries.

Using physical and electrochemical probes, the researchers discovered that under varying cycling rates and loadings, even at high current densities, a silica-based cathode showed better cycle-life in lithium-sulfur batteries.

New cathode coating extends lithium-ion battery life and boosts safety

A three-year project by the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Hong Kong University of Science and Technology (HKUST) has made a breakthrough in improving lithium-ion batteries.

Researchers used a coating called PEDOT to completely protect each particle of the cathode — inside and out — from reacting with the electrolyte, which improves lithium-ion battery cycle life and safety.
