LiCoO2, discovered as a lithium‐ion intercalation material in 1980 by Prof. John B. Goodenough, is still the dominant cathode for lithium‐ion batteries (LIBs) in the portable electronics market due to its high compacted density, high energy density, excellent cycle life and reliability. In order to satisfy the increasing energy demand of portable electronics such as smartphones and laptops, the upper cutoff voltage of LiCoO2‐based batteries has been continuously raised for achieving higher energy density. However, several detrimental issues including surface degradation, damages induced by destructive phase transitions, and inhomogeneous reactions could emerge as charging to a high voltage (>4.2 V vs Li/Li+), which leads to the rapid decay of capacity, efficiency, and cycle life. In this review, the history and recent advances of LiCoO2 are introduced, and a significant section is dedicated to the fundamental failure mechanisms of LiCoO2 at high voltages (>4.2 V vs Li/Li+). Meanwhile, the modification strategies and the development of LiCoO2‐based LIBs in industry are also discussed.

“…58 In particular, cyclic carbonates, glymes, and room temperature ionic liquids 59 have been used as plasticizers that may decrease viscosity and modulus of polymer electrolytes, while improving ionic conductivities, though at expense of mechanical stability. 42 In cases where plastic crystals 60 are used as additives, the GPEs are called liquid crystal polymer electrolytes [61][62][63] or ionic plastic crystals. 64 GPEs afford reasonably high ionic conductivities, good interfacial properties, and acceptable electrochemical stability depending on the auxiliary solvent(s), even if the dimensional stability and operational safety still constitute remaining challenges to overcome.…”

Among so-called “next generation” battery technologies, lithium metal batteries (LMBs) enabled by solid-state electrolytes are considered key to achieve rechargeable batteries with higher energy density and safety than current lithium ion batteries (LIBs). This article briefly evaluates various aspects of polymer electrolytes from history, macromolecular architecture, material classification, and electrode optimization, with special emphasis on solid polymer electrolytes (SPEs) and single ion conducting polymeric electrolytes. Representative interfaces and interphases as well as corresponding engineering strategies adopted for the anticipated goals are briefly summarized, including various approaches adopted to mitigate the shortcomings at the interfaces. Significant weight should be given for research and development of SPEs, as they could be an enabler for solid-state LMBs with attractive performance and made by comparatively easy electrode and cell processing techniques.
