▎ 摘  要

NOVELTY - Sodium ion battery cathode material comprises a cathode main material, a conductive agent and agglomerant agent. The ratio of cathode main material, conductive agent and agglomerant is 100:(1-5):(1-5). The cathode main material is graphite, soft carbon and hard carbon with the mass ratio of (0-5):(0-15):(80-98). USE - Used as sodium ion battery cathode material. ADVANTAGE - The sodium ion battery cathode has high sodium storage capacity, good lubricity, flexibility, plasticity and high conductivity, good multiplying power performance, low temperature performance and cycle performance, reduces the resistance cathode, and improves the processing performance of the cathode. The cathode has high compaction density, and the pole piece has good flexibility and good conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an sodium ion battery cathode material which is prepared by cathode sheet.
