Abstract: Composite solid polymer electrolytes (SPE), organic cathode electrodes, and solid-state lithium batteries (SLBs) that incorporate the SPE and/or the organic cathode electrodes. The composite solid polymer electrolytes include a hybrid polymer matrix, an LiTFSI salt dispersed in the matrix polymer matrix, and an LLZTO ceramic filler dispersed in the matrix polymer matrix. The organic cathode electrodes contain perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA).

Abstract: Ether-based electrolytes for lithium metal batteries, lithium metal batteries, and methods of their use. Such an ether-based electrolyte includes a highly-nonpolar, nonfluorinated dipropyl ether (DPE) solvent that enhances the oxidation stability of a lithium metal battery. Such a lithium metal battery includes the ether-based electrolyte electrochemically coupling an anode and cathode of the battery.
