As one of the landmark technologies, Li-ion batteries (LIBs) have reshaped our life in the 21stcentury, but molecular-level understanding about the mechanism underneath this young chemistry is still insufficient. Despite their deceptively simple appearances with just three active components (cathode and anode separated by electrolyte), the actual processes in LIBs involve complexities at all length-scales, from Li+ migration within electrode lattices or across crystalline boundaries and interfaces to the Li+ accommodation and dislocation at potentials far away from the thermodynamic equilibria of electrolytes. Among all, the interphases situated between electrodes and electrolytes remain the most elusive component in LIBs.

解读锂离子电池中的碳酸亚乙酯-碳酸亚丙酯的奥秘

作为具有里程碑意义的技术之一,锂离子电池(LIB)重塑了我们在21世纪的生活,但是对于这种年轻化学作用机理的分子水平了解仍然不足。尽管表面上看似简单,只有三个活性成分(阴极和阳极被电解质隔开),但LIB的实际过程涉及所有长度范围的复杂性,从Li +在电极晶格中迁移或跨晶界和界面到Li +调节和位错离电解质的热力学平衡很远。其中,位于电极和电解质之间的中间相仍然是LIB中最难以捉摸的成分。
