Realization of an anti-pulverization electrode structure is extremely important for developing high-performance Li/Na storage, and yet this technology is still challenging. Herein, the yolk-shell Co₉S₈/ZnS heterostructure encapsulated by N, S-doped carbon (YS Co₉S₈/ZnS@SNC) is successfully synthesized from solid CoZn glycerate microsphere for the first time and utilized as the anode materials for Li/Na storage. Consequently, the optimized YS Co₉S₈/ZnS@SNC electrode exhibits superior Li/Na storage performance, involving excellent reversible capacity and outstanding rate capability with high specific capacity. The superior performances of the electrode are attributed to the two factors: ⅰ) The YS structure can not only accommodate the volume variation effectively to resist pulverization during Li/Na-ions insertion/extraction, but also enable sufficient contact of Co₉S₈/ZnS and electrolyte to improve electron/ion transportation in the electrode; ⅱ) in-situ constructed Co₉S₈/ZnS heterostructure and its surface coated SNC layer can provide a high efficient transfer path for electrons. Density functional theory calculations further confirm the excellent conductivity of the Co₉S₈/ZnS and its delocalized electron distribution. Importantly, the strategy provides a new opportunity to realize high-performance energy storage from various glycerate template-based transition metal compounds.

实现抗粉化电极结构对于开发高性能锂/钠存储极为重要，但该技术仍具有挑战性。在此，首次成功地从固体CoZn甘油酸微球合成了由N，S掺杂碳包裹的蛋黄壳Co ₉ S _{8 /ZnS异质结构（YS Co 9} S ₈ /ZnS@SNC）并用作负极材料。用于锂/钠存储。因此，优化的 YS Co ₉ S ₈/ZnS@SNC电极表现出优异的锂/钠存储性能，包括优异的可逆容量和高比容量的优异倍率性能。电极的优异性能归因于两个因素：ⅰ) YS结构不仅可以有效地适应体积变化以抵抗Li/Na离子嵌入/脱出过程中的粉化，而且使Co ₉ S ₈ / ZnS 和电解质，以改善电极中的电子/离子传输；ⅱ)就地建造的 Co ₉ S ₈/ZnS异质结构及其表面涂覆的SNC层可以为电子提供高效的传输路径。密度泛函理论计算进一步证实了Co ₉ S ₈ /ZnS 的优异导电性及其离域电子分布。重要的是，该策略为从各种基于甘油酸模板的过渡金属化合物实现高性能储能提供了新的机会。
