我们通过对同步加速器X射线衍射数据进行结构精修证明，在重要的Li - N - H储氢系统中，氢循环过程中酰胺锂和亚胺锂之间的转变机制是一种体相可逆反应，它在类立方反萤石结构的Li - N - H中以非化学计量的方式发生。
We demonstrate, through structural refinement from synchrotron X-ray diffraction data, that the mechanism of the transformation between lithium amide and lithium imide during hydrogen cycling in the important Li-N-H hydrogen storage system is a bulk reversible reaction that occurs in a non-stoichiometric manner within the cubic anti-fluorite-like Li-N-H structure.
