Definitions

  • the negative electrode active material has a low-temperature phase Li 4 WO 5 -type structure means that the negative electrode active material has an ICDD Card No. It means having a crystal structure that can be assigned to 01-074-6445.
  • a negative electrode active material having a low temperature phase Li 4 WO 5 type structure means that the negative electrode active material (especially particles thereof) is a mirror specific to the so-called low temperature phase Li 4 WO 5 type crystal structure in X-ray diffraction. It means exhibiting one or more major peaks corresponding to the index at a given angle of incidence.
  • the low temperature phase Li 4 WO 5 type structure is the so-called ⁇ -Li 4 WO 5 type structure.
  • the volume ratio of the sintering aid in the negative electrode layer can be measured by the same method as the volume ratio of the negative electrode active material.
  • B boron
  • B can be detected by EDX and determined to be the sintering aid region.
  • the solid-state battery of the present invention may further have all the members that conventional solid-state batteries can have, such as a positive electrode current collecting layer, a negative electrode current collecting layer, a protective layer, end face electrodes, and the like.
  • high temperature phase Li 4 WO 5 means “single phase structure of high temperature phase Li 4 WO 5 type crystal structure”.
  • the crystal structure was determined by the method described above based on the peaks and their intensities specific to each crystal structure in X-ray diffraction (XRD using CuK ⁇ rays). The same applies to Tables 2 and 3 below.
