Li2TiO4化学式对吗？怎么读。可以做负极材料吗？ 有篇综述讲钛的，不记得了，有个总结-----------http:///s/blog_81440d6f01015y2z.html#page=2相比现在通用的石墨，氧化钛作为锂电池负极材料有明显的优点也有明显的缺点。下面比较了不同类型的氧化钛作为负极材料的特点。----------------------------------------- ti-o system in generalas compared to graphite, which is commercially used as anode in lithium ion batteries, the ti-o system has the advantage of high rate and absence of solid electrolyte interphase (sei) formation, but suffers from its low conductivity.in the following discussion, the maximum theoretical capacity has to be distinguished from practical capacity. all tio2 have the same max theoretical capacity: litio2, that is, 1 li per ti or 336 mahg-1. however, this theoretical capacity is limited by several parameters such as phase, particle size, etc. b-tio2 shows the higher practical capacity for similar conditions since li-ion diffusion is higher. beta-tio2 (tio2-b)-??higher capacity than any other li-ti-o system or tio2 polymorphs-??monoclinic, space group c2/m, parallel channel along [010], corner-sharing tio6 octahedral-??metastable phase-??favour insertion and diffusion of li along the channel-??performance strongly depending on microstructure-??synthesis: hydrothermal, sol-gel, solvothermal methods-??problem: rate capacity due to low electron conductivity, can possibly improved by doping rutile tio2-??uptake only 200 mah/g, 1.5 v-??poor cycling performance, significant loss of capacity in the first few cycles， 查看更多
