Description
Summary:Understanding the electrode/electrolyte interfacial chemistry is the cornerstone of designing lithium-ion batteries (LIBs) with superior performance. Graphite has been exclusively utilized as the anode material in state-of-the-art LIBs, whose interfacial chemistry has a profound impact on battery life and power delivery. However, current understanding of the graphite/electrolyte interface is still incomplete because of its intricate nature, which has driven unremitting explorations and breakthroughs in the past few decades. On the one hand, the applications of emerging experimental and computational tools have led researchers to re-examine several decades-old problems, such as the underlying mechanism of solid electrolyte interphase (SEI) formation and the co-intercalation mystery. On the other hand, from anion-derived interfacial chemistry to artificial interphases, novel interfacial chemistry for graphite is being proposed to replace the traditional ethylene carbonate-derived SEI for better performances. By summarizing the latest advances in the emerging interfacial chemistry of graphite anodes in LIBs, this review affords a fresh perspective on interface science and engineering towards next-generation energy storage devices. Emerging interfacial chemistry of the graphite anode in today's lithium-ion batteries paves the way to next-generation, high-performance energy storage devices.
