▎ 摘  要

NOVELTY - Organic anode material comprises a metal coordination polymer, where organic groups in the metal coordination polymer comprises nitrile groups and hexaazatriphenylene groups. USE - Organic anode material. ADVANTAGE - The metal ions are complexed with nitrogen-containing organic compounds to form metal-organic coordination polymers, which greatly suppress the decay of small organic molecules, which further endow the coordination polymers with strong cycling stability and electrical conductivity, and respectively maintains high capacity after 200 cycles at a current density of 0.1 C (40 mA g-1). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an organic anode material, which involves: (1) mixing an organic matter containing hexaazatriphenylene and/or an organic matter containing nitrile group, metal ions and an organic solvent, and performing ultrasonic dissolution to obtain a solution to be reacted; (2) heating and reacting the solution to be reacted to obtain a reaction product; (3) cooling, cleaning and drying the reaction product.
