NEGATIVE ELECTRODE FOR NONAQUEOUS ELECTROLYTE ELECTRICITY STORAGE ELEMENTS, NONAQUEOUS ELECTROLYTE ELECTRICITY STORAGE ELEMENT, AND ELECTRICITY STORAGE DEVICE

摘要

In order to improve the insulating properties of a filler-containing coating layer that is provided on at least a part of the surface of a negative electrode mixture layer, a negative electrode for nonaqueous electrolyte electricity storage elements is configured to comprise, on a collector, a negative electrode mixture layer that contains a negative electrode active material and a filler-containing coating layer that is provided on at least a part of the surface of the negative electrode mixture layer. This negative electrode for nonaqueous electrolyte electricity storage elements is also configured such that the peak intensity ratio of the diffraction peak belonging to the (002) plane of the negative electrode active material to the diffraction peak belonging to the (100) plane of the negative electrode active material, namely (I(002)/I(100)) in X-ray diffractometry (XRD) of this negative electrode is from 219 to 862 (inclusive).
