Three-dimensional porous LiMnPO4/nitrogen-doped graphene aerogel

Three-dimensional porous LiMnPO4/nitrogen-doped graphene aerogel is a new composite material that combines the advantages of LiMnPO4 cathode material and nitrogen-doped graphene aerogel. This material not only inherits the high energy density and long cycle life of LiMnPO4, but also enhances its conductivity and structural stability through the introduction of nitrogen-doped graphene aerogel, thus improving the overall performance.The preparation method of three-dimensional porous graphene aerogel material includes: mixing graphene oxide dispersion and organic amine, hydrothermal reaction to obtain hydrogel; water washing, freezing and drying to obtain three-dimensional porous graphene aerogel material.
