Title:
NONAQUEOUS SECONDARY BATTERY FUNCTIONAL LAYER COMPOSITION, NONAQUEOUS SECONDARY BATTERY FUNCTIONAL LAYER, AND NONAQUEOUS SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2017/033431
Kind Code:
A1
Abstract:
Provided is a nonaqueous secondary battery functional layer composition capable of improving electrical characteristics of a secondary battery. The nonaqueous secondary battery functional layer composition according to the present invention contains an inorganic substance. When the diffraction intensity and the diffraction angle 2θ obtained through a X-ray diffraction method performed on the inorganic substance are respectively represented by the vertical axis and the horizontal axis, and when the total integrated sum of the diffraction intensity within diffraction angle 2θ = 3° to 90° in the X-ray diffraction pattern is defined as 100%, the interplanar spacings corresponding to 2θ are 0.1-0.4 nm and 0.15-0.70 nm at positions where the total integrated sum of the integrated sum of the diffraction intensity integrated from the high diffraction angle side becomes 50% and 80%, respectively.
