摘要

封面展示了通过三维结构和卤化物取代实现的钴层氢氧化物超级电容器性能的优势。与六方结构相比，α-钴羟基卤化物的三维花朵状形态显著提高了其电化学性能。通过用碘化物取代氯化物，电容性能进一步提高了 40% 以上，从而展示了卤化物在调节电子特性方面的关键作用。这一成果使这些材料有望成为能量存储的候选材料。更多信息，请参阅 V. Oestreicher、G. Abellán 及合作者的研究文章（DOI: 10.1002/batt.202400335）。

Cover Picture: Enhancing the Supercapacitive Behaviour of Cobalt Layered Hydroxides by 3D Structuring and Halide Substitution (Batteries & Supercaps 11/2024)

The Front Cover illustrates the advantages in the supercapacitive behaviour of cobalt-layered hydroxides achieved through 3D structuring and halide substitution. The 3D flower-like morphology of α-Co hydroxyhalides significantly enhances their electrochemical performance compared to the hexagonal structure. By substituting chloride with iodide, the capacitive behaviour is further improved by over 40 %, thereby showcasing the critical role of halides in modulating electronic properties. This achievement makes these materials promising candidates for energy storage. More information can be found in the Research Article by V. Oestreicher, G. Abellán and co-workers (DOI: 10.1002/batt.202400335).
