在本文中，我们给出了在不同荷电态（SOC）下的特定Li2MnSiO4晶粒结构的现场观察。这些研究的目的是利用透射电子显微镜对锂离子电池正极材料Li2MnSiO4在电化学反应不同阶段的结构进行分析。分析表明，Li2MnSiO4的非晶化过程与锂离子脱嵌没有直接关系，而是与工作电池中发生的附加电化学反应有关。
In this paper, we present exsitu observations of a structure of particular Li2MnSiO4 grains at different states of charge (SOC). The goal of these studies is structural analysis of Li2MnSiO4 cathode material for Li-ion batteries at different stages of electrochemical reaction using transmission electron microscopy. Performed analysis suggests that amorphization process of Li2MnSiO4 is not directly connected with lithium ions deintercalation but with additional electrochemical reactions running in the working cell.
