Abstract

A facile protocol is developed for the direct observation and characterization of a single particle electrode during the lithium ion battery operation by using in situ AFM. The SEI formation on the LiNi_0.5Mn_1.5O₄ particle cathode surface is found to be highly related to the exposed planes.
