摘要

层状LiMnO2被认为是最有发展前途的锂离子电池正极材料之一

是目前新能源材料研究的热点.本文研究了高温固相法+碳热还原法

离子交换法

水热合成法和流变相法等多种工艺制备层状LiMnO2

通过实验结果对比了各种制备工艺工业化的可行性

为层状LiMnO2实现商业化提出了建议.研究结果表明:水热合成法在160℃下

Li/Mn=2∶1时

可得到层状LiMnO2;而流变相法在Li/Mn=1∶1时

即可得到LiMnO2.

Abstract

The layered LiMnO2

being regarded as one of the most promising positive materials of lithium-ion battery

is the hot spot of new energy materials research at present.In this paper

we discuss various kinds of preparation technologies of layered LiMnO2

such as the high temperature solid phase method combined with carbon reduction method

ion-exchange method

hydrothermal synthesis method and rheological phase method.We discuss the technologies′ feasibility for industrialization

and make a proposal for the commercial development.The results from above investigation showed that the layered LiMnO2 was obtained when hydrothermal synthesis was at 160 ℃ and the ratio of Li/Mn was 2∶1.The layered LiMnO2 was obtained through rheological phase method when the ratio of Li/Mn was 1∶1.
