Multifunctional Membrane for Enhanced Lithium Batteries
Researchers at Purdue University have developed a multifunctional membrane separator to uniformly distribute Li-ion flux to minimize the lithium dendritic growth, eventually suppressing Li dendrites formation. Structural and materialistic benefits of the membrane allow significant enhancement of electrochemical performances of Li metal batteries. In addition, the membrane selectively allows Li ions to pass through the membrane while preventing the passage of unwanted compounds, effectively increasing efficiency and extending the lifetime of the metal batteries. The membrane can be coupled with next-generation batteries, e.g., Li-S, Li-air, requiring Li metal (or Na metal) as an anode and easily and effectively increase the energy density of secondary batteries. The selection of material for designing the membrane can be expanded to other types of material to advance the development and commercialization of practical metal batteries.
