Public Abstract	Lithium metal batteries are a promising approach for increasing the energy density of batteries; however, they can suffer from poor cyclability, dendritic deposition, and cathode electrolyte interface problems. Researchers at Purdue have developed ether-based electrolytes that are cost effective, improve the anodic stability of ethers at high-voltage and enhance the oxidation stability of the battery. This technology overcomes the limitations of existing ether-based electrolytes that hinder their practical applications in high-voltage conditions. Technology Validation: - Ultra-high coulombic efficiency (99.90 %, 4.3 V) seen after stable cycling within a practical LMB. Advantages: - Better anode and cathode compatibility with high ionic conductivity as well as small interfacial resistance when used in an LMB - High performance of high-voltage Li metal batteries seen, especially at low temperatures. Applications: - ¬Lithium Metal Batteries
