Uniform distribution of LiMnO and LiMO components in a Co-free Li-rich layered oxide is achieved by treating precursors with NH·HO, which expands the lattice parameter and promotes the activation of LiMnO, resulting in excellent electrochemical performance. What's more, it also contributes to the storage stability of Li-rich layered oxides.
通过用NH·HO处理前驱体，可实现无钴富锂层状氧化物中LiMnO和LiMO组分的均匀分布，这会扩大晶格参数并促进LiMnO的活化，从而产生优异的电化学性能。此外，它还有助于富锂层状氧化物的存储稳定性。
