摘　　要：随着新能源汽车的大批量应用,作为新能源汽车主要动力源的锂离子电池发展迅速。由于市场对锂的需求量增加,锂的储量问题逐渐显露,锂离子电池上游原材料价格逐渐走高。而钠离子电池与锂离子电池相比,具有钠盐原材料储量丰富、价格低廉等优势,从而被人们考虑作为低成本补充产品。本文着重关注近年来国内在钠离子电池正极材料方面的专利申请情况,并对重点申请人的专利申请状况进行分析。With the large-scale application of new energy vehicles,lithium-ion batteries,which are the main power source of new energy vehicles,have developed rapidly.Due to the increasing demand for lithium in the market,the problem of lithium reserves has gradually emerged,and the price of upstream raw materials for lithium-ion batteries has gradually increased.Compared with lithium-ion batteries,sodium-ion batteries have the advantages of abundant reserves of sodium salt raw materials and low prices,so they are considered as low-cost supplementary products.This paper focuses on the domestic patent applications in the field of cathode materials for sodium-ion batteries in recent years,and analyzes the patent application status of key applicants.
