Abstract: 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.

Key words: ion batteries, phase transition, phase diagram
