Abstract

Abstract : In article number1704309, Minjoon Park, Jaephil Cho, and co‐workers develop a nickel‐rich cathode with an artificial solid electrolyte interphase (SEI) layer that can be electrochemically rearranged along grain boundaries. The cathode with the incorporated artificial SEI layer exhibits not only outstanding electrochemical performance at high temperature, and even at high cut‐off voltage, but also structural integrity after electrochemical testing. These results provide a rational approach for the development of advanced cathode materials.
