The present invention pertains to a method for producing a sulfide solid electrolyte, the method comprising: introducing sulfide solid electrolyte raw materials into a heated furnace body and mixing the same to obtain a mixture of the sulfide solid electro...

To provide a solid electrolyte, an electrolyte composition, an electrolyte sheet, and a power storage device, in which gelling is suppressed. The solid electrolyte (18) has a garnet-type structure which contains Li, La, Zr, and O, in which, with respect to...

A solid electrolyte material of the present disclosure includes Li, Zr, Y, Cl, and O, the molar ratio of O to Y in the entire solid electrolyte material is greater than 0 and less than or equal to 0.80, and the molar ratio of O to Y in the surface region o...

A lithium ionic conductor (solidelectrolyte) contains lithium (Li),phosphorus (P), boron (B) and sulfur (S) asconstituentelements and has a crystal structure that boron (B) is substituted for part of phosphorus (P) in the β structure of LiPS.

Problem Provided are an additive for an electrolytic composition which can suppress the decrease of a short-circuit current and improve an open circuit voltage as compared to the case when conventional 4-TBpy is used as an additive for an electrolytic comp...

An electrolyte composition is in solid form, and includes a polymer compound containing a cation structure selected from a group consisting of ammonium, phosphonium and sulfonium structures in either the principal chain or a side chain of the polymer, and ...

The present invention relates to a solid electrolyte including Li, O, P and a transition metal element. In the solid electrolyte, because the transition metal element T is reduced prior to phosphorus atoms, it is possible to prevent the valence of phosphor...

A mixed conductor of this invention includes an electron conductor made of a carbon-based inorganic material imparted electron conduction by causing a main chain to have a π bond, and a proton conductor made of an inorganic material having proton conducti...
