A vehicle window glass of the present invention includes a glass plate and an antenna. The antenna includes a feeding portion and an antenna element. The antenna element includes a first vertical element, a first loop element, and a first folded-back eleme...

A head-up display system for vehicles, which has a light source that emits p-polarized visible light, and laminated glass to which the p-polarized visible light is incident from the vehicle interior side, and which displays a virtual image on the vehicle e...

A sulfide solid electrolyte powder includes a crystal phase. A value represented by [(strain value−0.001)/specific surface area (m/g)]×100 is 0.010 to 0.070, and the crystal phase comprises an argyrodite crystal structure. The sulfide solid electrolyte ...

A method for producing a sulfide solid electrolyte, includes: heating and melting a wet-pulverized first sulfide solid electrolyte to obtain a melt, and removing carbon from the melt; and cooling the carbon-removed melt to obtain a second sulfide solid ele...

A sulfide solid electrolyte powder includes, in content in a mass basis: less than 50 ppm of Al; and less than 50 ppm of Zr. A particle diameter D50 is less than 1 μm. A BET diameter calculated based on a BET specific surface area may be 0.10 μm to 0.30 ...
