在重点研究尖晶石结构limn 。 o 。正极材料的基础上，对目前国内外研究较少的另一类理锰氧化物正极材料? ?层状limno 。 - During the research of suppressing jahn - teller distortion , low valence cation doped method are usually adopted . this method can improve the cyclability of batteries , but it will also lead to the decreasing of initial capacity
单独s掺杂消除了尖晶石在3v电压区jahn - teller畸变， 3v电压区的容量，在前20次循环中不但没有降低反而逐步增加，到一定值后趋于稳定。 - For resolve the jahn - teller effect , improve the capacities and cycle performance and decrease the cell price , a series of spinel lithium manganese oxides doped by lithium , nickel and titanium were prepared by liquid method
为解决尖晶石锂锰氧化物在进行深度充放电时的jahn - teller效应问题，提高电池的比能量和电池寿命以及降低电池成本等问题，本文用液相法合成出一系列用锂、镍、钛掺杂的尖晶石锂锰氧化物。 - Because f - doped increases the content of mn3 + , which is the active ion at oxido - reduction , so f - doped can increase the initial capacity , but the increased mn + intensified the jahn - teller distortion and the dissolution of mn2 + , both of which deteriorated the cyclability
表面修饰后的limn _ 2o _ 4晶粒具有良好的抗电解液溶蚀能力， mn的溶解量仅是未经表面修饰材料的1 / 2左右；虽然首次放电容量有所降低，但其循环性能优良。 - The capacity fading has several possible reasons , including manganese dissolution , distortion of the crystal lattice due to the jahn - teller effect and electrolyte oxidation . doping the spinel with al and mg was introduced in this paper to improve performance of li - ion batteries cathode material . in this work , spinel limn2o4 and lialxmn2 - xo4 and limgymn2 - yo4 have been synthesized by a sol - gel - complexation method and their structure and electrochemical properties have been examined
