Abstract

Back cover image: Layered manganese dioxide (δ-MnO₂) cathodes for aqueous zinc-ion batteries offer high capacity but suffer from sluggish Zn²⁺ diffusion and severe manganese dissolution. In article number e70014, Ding et al. engineer a dual-functional δ-MnO₂ cathode modified with 2-methylimidazole. This synergistic molecular design combines pre-intercalation to expand interlayer spacing (accelerating Zn²⁺ diffusion) and surface coating to form stabilizing Mn–N bonds (suppressing Mn²⁺ dissolution), achieving exceptional capacity and cycling stability.

后盖图片：层状二氧化锰（δ-MnO2）阴极用于含水锌离子电池提供高容量，但受到缓慢的Zn2+扩散和严重的锰溶解的影响。在文章编号e70014中，Ding等人设计了一种用2-甲基咪唑修饰的双功能δ-MnO2阴极。这种协同的分子设计结合了预插入来扩大层间间距（加速Zn2+扩散）和表面涂层来形成稳定的Mn-N键（抑制Mn2+的溶解），实现了卓越的容量和循环稳定性。
