摘　　要：新能源汽车、智能电网等产业的飞速发展推动了电池储能技术的革新。二氧化锡因其理论比容量高、储量丰富等优点,被认为是替代锂离子电池传统石墨负极的潜在选择。然而,由于二氧化锡存在首次库伦效率低、循环寿命短和导电性差等问题,使其商业化应用受到限制。针对二氧化锡电化学储锂的性能缺陷,综述了二氧化锡负极材料的改性策略及其研究进展,并对二氧化锡在锂离子电池领域的应用前景进行了展望。The rapid developments of new energy vehicles and smart grids have driven the innovation of battery energy storage technology.Tin dioxide is considered as a potential alternative to traditional graphite anodes for lithium-ion batteries due to its high theoretical specific capacity and abundant reserves.However,the commercial application of tin dioxide is limited by its low initial coulombic efficiency(ICE),short cycle life and poor electrical conductivity.In this paper,we focus on the performance drawbacks of tin dioxide for electrochemical lithium storage,and introduce the modification strategies of tin dioxide anode materials and their research progress.Furthermore,we prospect the application of tin dioxide in the field of lithium-ion batteries.
