SOLID-ELECTROLYTE BATTERY |
摘要 |
A solid-electrolyte battery is provided that includes a LiNbO 3 film serving as a buffer layer between a positive-electrode active material and a solid electrolyte and has a sufficiently low electrical resistance. The solid-electrolyte battery includes a positive-electrode layer, a negative-electrode layer, and a solid-electrolyte layer that conducts lithium ions between the electrode layers, wherein a buffer layer that is a LiNbO 3 film is disposed between a positive-electrode active material and a solid electrolyte, and a composition ratio (Li/Nb) of Li to Nb in the LiNbO 3 film satisfies 0.93 ‰¤ Li/Nb ‰¤ 0.98. The buffer layer may be disposed between the positive-electrode layer and the solid-electrolyte layer or on the surface of a particle of the positive-electrode active material. The buffer layer may have a thickness of 2 nm to 1 µm. |
