▎ 摘　　要

NOVELTY - Foam-shaped three-dimensional porous structure material is claimed. The material is porous three-dimensional conductive network material prepared by cross-linking glucose and PTFE through hydrogen bonds, freeze-drying and high-temperature carbonizing to decompose and volatilize the PTFE cross-linked with glucose and carbonizing the glucose. The microstructure of the material is many turbulent layer structures containing amorphous carbon, and the turbulent layer structure contains graphene layers, and uniformly dispersed holes in the material interlink to form interconnected channels. USE - The foam-shaped three-dimensional porous structure material is useful as potassium storage cathode material for potassium-ion battery (all claimed). ADVANTAGE - The foam-shaped three-dimensional porous structure material: provides idea for construction of high-capacity and high-stability potassium storage cathode materials; and is suitable for structural design of other potassium storage electrodes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of foam-shaped three-dimensional porous structure material.
