The Cover Feature represents a roadmap to the optimisation of Li‐ion batteries for electromobility applications. As the positive electrodes (i. e., cathodes) currently represents the bottleneck for increasing the energy density of a Li‐ion system, in order to enable the next‐generation of high energy density Li‐ion batteries, more attention needs to be focused on the investigation of the surface layer (or interphase) formed on these electrodes. Such interphase might behave as a protective layer allowing higher operating potentials, and therefore higher energy density of the battery, without compromising the stability of the electrolyte and the cycle life of the Li‐ion cell. Thus, it is of fundamental importance to combine the knowledge obtained from many diverse analytical tools, both established and novel, in order to gain a broader and more comprehensive view of the role and the nature of such surface layers. More information can be found in the Review by G. Zampardi and F. La Mantia.
封面功能 代表了针对电动汽车应用优化锂离子电池的路线图。由于正电极（即阴极）目前是增加锂离子电池系统能量密度的瓶颈，因此，要实现下一代高能量密度锂离子电池，就需要更多地关注锂离子电池。研究在这些电极上形成的表面层（或中间相）。这种相间可作为保护层，允许更高的工作电势，从而提高电池的能量密度，而不会损害电解质的稳定性和锂离子电池的循环寿命。因此，最重要的是将从多种多样的分析工具（既有的又新颖的）中获得的知识相结合，为了更广泛，更全面地了解此类表面层的作用和性质。有关更多信息，请参见G. Zampardi和F. La Mantia的评论。
