An In Situ Formed Surface Coating Layer Enabling LiCoO2 with Stable 4.6 V High‐Voltage Cycle Performances

The development of high‐voltage LiCoO2 is essential for achieving lithium‐ion batteries with high volumetric energy density, however, it faces a great deal of challenges owing to the materials, structure and interfacial instability issues. In this work, a strategy is developed, through heat annealin...
