Using an electrolyte additive enables a nickel-rich layered cathode to be cycled at high voltages and still retain 97% of its initial capacity after 200 cycles. The decomposition of the electrolyte additive leads to the formation of a robust interphase that protects the surface of the cathode, preserving the capacity and preventing cracks.

电解质添加剂可实现富镍层状阴极的稳定高压循环

使用电解质添加剂可使富镍层状阴极在高压下循环，并在 200 次循环后仍保持其初始容量的 97%。电解质添加剂的分解导致形成坚固的界面，保护阴极表面，保持容量并防止裂纹。
