钠离子电池过渡金属氧化物正极材料研究进展OA北大核心CSTPCD

In recent years,sodium ion battery(SIBS)has gradually become a research hotspot in the field of energy storage due to rich resources and low prices.However,sodium ions have a larger ion radius and slower kinetic rate,which have become the main factors restricting the development of so-dium storage materials.The development of high-performance sodium embedded cathode materials is the key to improving the specific energy of sodium ion batteries and promoting their applications.The research work on oxide based sodium embedded cathode material systems in recent years was focused on,the latest research progress of transition metal oxide based cathode materials in SIBs in the past decade was reviewed,and the relationship between improving the structure and electro-chemical performance of transition metal oxide based cathode materials was explored.Possible ways to improve the reversible capacity,voltage,and structural stability of cathode materials were ana-lyzed,and reference for the development of SIBs electrode materials was provided.
