Title:
CURED PRODUCT FOR LITHIUM ION SECONDARY BATTERIES, NEGATIVE ELECTRODE FOR LITHIUM ION SECONDARY BATTERIES, AND LITHIUM ION SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/057643
Kind Code:
A1
Abstract:
This cured product for lithium ion secondary batteries comprises water-soluble polymers, a crosslinking agent and cellulose nanofibers. The crosslinking agent crosslinks the water-soluble polymers different from each other, or the water-soluble polymers and the cellulose nanofibers. If measured by means of wide-angle X-ray scattering (WAXS) using a CuKα ray, the diffraction angle 2θ has a peak within the range of 16° to 21°. The half-value width of the peak is 5.5° or less.
