火焰喷雾热解制备锂离子电池三元正极材料研究进展
Progress in synthesis of ternary cathode materials for lithium-ion batteries by flame spray pyrolysis
摘要
Abstract
The development of electrochemical energy storage technologies and the large-scale application of electric vehicles are critical for the reduction of carbon emissions.Lithium-ion batteries are the core components of electric energy storage technologies and electric vehicles with high energy density and long cycle life,yet their capacity is mainly limited by cathode materials.Ternary cathode materials have the advantages of light pollution,low cost,high performance and large capacity.However,the conventional wet chemistry and high-temperature solid-state methods are usually multi-step procedures and time-consuming,which are the major hurdlers for commercialization.The flame spray pyrolysis(FSP)method has attracted wide attention,given that it can produce ternary cathode materials in one step without waste produced during the synthesis process and thus has little impact on the environment.The present study reviewed the research progress in the preparation of ternary cathode materials by FSP method in recent years.Firstly,the history,advantages,basic principles and typical devices of FSP were briefly introduced.Secondly,the effects of precursor solution composition,synthesis temperature and annealing conditions on the composition,structure,morphology and electrochemical properties of ternary cathode materials were analyzed.Then,the recent research progress in the modification and deposition technologies of terpolymer cathode materials was briefly described.Finally,the future development trend of ternary cathode materials prepared by FSP was prospected.关键词
