▎ 摘　　要

NOVELTY - Preparation of biomass-based three-dimensional multi-chamber graphene-like carbon capsules involves dissolving sodium phytate in a solvent, stirring, adding dried Ganoderma spore powder, stirring to form a gel-like mixture, drying, treating at high temperature under an inert atmosphere, cooling, and post-treating. USE - Preparation of biomass-based three-dimensional multi-chamber graphene-like carbon capsules for energy storage materials (claimed). ADVANTAGE - The three-dimensional multi-chamber graphene-like carbon capsules having high specific surface area and capable of increasing storage capacity of sodium ions can be produced.
