摘要
相变是电池材料基础研究中的重要问题。对材料相变的准确认识,有利于合成制备过程中获得晶体结构与组成符合设计要求的目标材料。了解电解质中的相变可以知道其使用的安全稳定条件,利用其相变性质发展新的电解质材料。相的组分与相变趋势可以由相图简明直观地展示出来。本文小结了与锂离子电池相关的相变与相图研究。
Phase transition is an essential problem in battery research. Understanding on phase transition in synthesis precisely is necessary to obtain target products with controlled structure and composition. Knowledge about phase transitions of electrolyte can offer the information of the safe and stable working condition, and provide a way to develop new electrolyte according to the characteristics of phase transition. Phase composition and phase evolution can be illustrated concisely and directly in phase diagram. This paper summarizes briefly typical research activities on phase transition and phase diagram in Li-ion batteries during material preparation.
