▎ 摘　　要

NOVELTY - Preparing porous MXene material comprises spraying and cracking the MXene dispersion to obtain the porous MXene material. The MXene dispersion further includes an interlayer spacer. The interlayer spacers include metal oxide, metal nitride, glucose and/or graphene oxide. USE - The porous MXene material is useful for lithium-ion battery cathode material (claimed). ADVANTAGE - The method provides the porous MXene material with high conductivity and excellent electrochemical performance, large interlayer spacing, large specific surface area, and high ion, excellent electronic conductivity, and large ionic conductivity. The lithium ion transmission is more convenient, and the lithium ion battery material cathode formed using the material has excellent performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for porous MXene material.
