Abstract:
A sodium all-solid secondary battery including: a cathode; an anode; a sulfide-containing electrolyte between the cathode and the anode; an oxide-containing electrolyte between the sulfide-containing electrolyte and the anode; and a first bonding layer between the oxide-containing electrolyte and the sulfide-containing electrolyte, wherein the cathode includes a cathode current collector and a cathode active material layer, the anode includes an anode current collector and an anode active material layer, and the first bonding layer includes a metal capable of forming an alloy with sodium, a sodium ion-conductive material, or a combination thereof.
Abstract:
A composite electrolyte including a polymeric ionic liquid; and an oligomeric electrolyte, wherein the oligomeric electrolyte includes an oligomer.
Abstract:
A redox flow battery. A metal-ligand coordination compound including an aromatic ligand that contains an electron withdrawing group is used as the catholyte and/or the anolyte so that a redox flow battery having high energy density and excellent charge/discharge efficiency may be provided.
Abstract:
A polymer electrolyte for a lithium battery, wherein the polymer electrolyte includes a polymerization product of a lithium ion conductive compound including an ethylenically unsaturated bond, a lithium ion conductive unit, and an ion-exchangeable functional group; and a heteroatom-containing ionic liquid polymerizable with the lithium ion conductive compound.
