Competitive Solid-Electrolyte Interphase Formation on Working Lithium Anodes
RuiXu, ChongYan, Jia-QiHuang
It is critical to understand competitive solid-electrolyte interphase (SEI) formation on lithium (Li) metal anodes from a fundamental perspective.
The solvation structure of lithium ions and the electric double-layer behavior at electrode/electrolyte interface are proposed as two primary principles to determine the preferential reduction reactions during SEI formation.
The kinetic competition between SEI formation and Li deposition is elucidated, the results of which are strongly associated with the final Li electroplating morphology.
Several internal and external parameters such as electrolyte formulation, current density, and temperature can be considered to modulate the SEI formation–Li deposition competition.原文链接
