摘要： An electric device using a sulfur-containing positive electrode active material is capable of improving capacity characteristics and charge-discharge rate characteristics. Among positive electrode materials for an electric device including a sulfur-containing positive electrode active material and a sulfur-containing solid electrolyte, a positive electrode material for an electric device showing a peak in a range of 1400 to 1450 cm-1 in a Raman spectrum of microscopic Raman spectrometry using a laser with a wavelength of 532 nm is used.

摘要： A secondary battery provides a means for inhibiting the growth of dendrite in a solid electrolyte layer while suppressing the decrease in ion conductivity in the solid electrolyte layer.
In the secondary battery, which includes a power-generating element formed by laminating a positive electrode which contains a positive electrode active material, a solid electrolyte layer which contains a solid electrolyte, and a negative electrode which contains a negative electrode active material, a binder having a Young’s modulus of 200 [MPa] or lower is further contained in the solid electrolyte layer.
