Title:
FIBER-STRUCTURED ELECTRODE MATERIAL AND PREPARATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/114575
Kind Code:
A1
Abstract:
Dislcosed is a fiber-structured electrode material, wherein the material is made of a nanofiber structure on a micron or submicron scale in diameter, and the fiber structure further comprises a porous structure with a nano-scale pore diameter and a porosity of 20% to 80%. The porous nanofiber is prepared by compounding a conductive material, a metal material and an ionic polymer, wherein the mass content of the conductive material and the metal in the nanofiber is 50%-99.9%, and the mass ratio of the metal material to the conductive material is 0.01-0.99. The composition of the nanofiber-structured electrode material involves an ionic conductor material and an electronic conductor material. Compared with the prior art, the electrode material of the present invention has an ordered, controllable structure, a good mass transfer performance, a high noble metal utilization rate, a high ion transmission efficiency and a strong practicability.
