Diverse reproduction modes of bio-organisms open new intriguing opportunities for biochemistry-enabled materials. Herein, a new strategy is developed to explore biodirected structures for functional materials via controlling the reproduction mode. Yeast with sexual or asexual reproduction mode are employed in this work. They result in two different biodirected structures, from bowl-like hollow hemisphere to "bubble-in-sphere" (BIS) structure, for the VN x O y /C composites. Benefitting from the hierarchical structure, nanoscale particles and conductive biomass-derived carbon base, both VN x O y /C biocomposites achieve high power/energy density, good reliability, and excellent long-term cycling stability in aqueous Zn-ion batteries. Deep investigations further reveal that different biodirected structures greatly influence the electrochemical properties of biocomposites. The bowl-like structures with thin shells and folded double layers achieve larger surface area and more active sites, which ensure their faster kinetics and better high rate capability. The BIS structures with a more compact assembly and higher stack capability are favorable to the better energy storage. Therefore, this work not only introduces a new clue to boost biodirected structures for functional materials, but also propels the development of Zn-ion batteries in diverse applications.

通过控制复制模式打开高性能 VN x O y /C 增强生物定向结构的大门。

生物有机体的多样化繁殖模式为生物化学材料开辟了新的有趣机会。在此，开发了一种新策略，通过控制复制模式来探索功能材料的生物定向结构。本工作采用有性或无性繁殖方式的酵母。对于 VN x O y /C 复合材料，它们产生了两种不同的生物定向结构，从碗状空心半球到“球内气泡”（BIS）结构。受益于分层结构、纳米级颗粒和导电的生物质衍生碳基，这两种VN x O y /C生物复合材料在水性锌离子电池中实现了高功率/能量密度、良好的可靠性和优异的长期循环稳定性。深入研究进一步表明，不同的生物定向结构极大地影响生物复合材料的电化学性能。具有薄壳和折叠双层的碗状结构具有更大的表面积和更多的活性位点，这确保了其更快的动力学和更好的高倍率性能。BIS结构具有更紧凑的组装和更高的堆叠能力，有利于更好的能量存储。因此，这项工作不仅为功能材料的生物定向结构提供了新的线索，而且推动了锌离子电池在多种应用中的发展。
