摘要

设计人工固体电解质相是将锂离子电池的容量损失降至最低的一项重要任务。在这里，通过原子层沉积产生的 TiO2 被用作硅纳米颗粒上的人工 SEI。在使用不含 FEC 的电解质进行评估时，这种涂层大大提高了循环稳定性。

Directing SEI formation on Si-based electrodes using atomic layer deposition

The design of artificial solid eletroctrolyte interphase is an important task to minimize capacity losses in Li-ion batteries. Herein, TiO2 created through atomic layer deposition was used as an artificial SEI on Si nanoparticles. Such coating led to substantial improvement of cycling stability when evaluated with FEC-free electrolyte.
