Front cover image: Lithium sulfide (Li2S)-based Li-S battery is a promising candidate for next-generation batteries. However, the insulating Li2S requires a high overpotential for its first activation and so far, therefore, it is rarely reported to achieve long-life Li-S batteries in high Li2S loading. In article number cey2.308, Kim et al. propose a high-loading, high energy, and long-life Li2S cathode featuring a three-dimensional (3D) uniform carbon matrix and a compact geometrical structure, providing new opportunities for realizing a practical Li-S battery.
