Abstract Currently, multi-dimensional scale controllable preparation of energy nano-materials is an important strategy to achieve high performance. To solve these issues, nano-structured lumpy particles and thin sheets of ammonium manganese phosphate hydrate (NMP) were designed and fabricated by facile solid-state reaction at room temperature and co-precipitation method, respectively. When used as anode for LIBs for the first time, the lumpy particles exhibits better electrochemical performance, such as higher discharge capacity, better cycling stability, rate capability, compared with the thin sheets NMP. For example, the lumpy particles NMP electrode delivers a high reversible specific capacity of 1307 mAh g-1 at 100 mA g-1 after 350 cycles, while the other NMP electrode presents only half. The excellent performance of nano-structured lumpy particles NMP can be ascribed to the smaller longitudinal-transverse ratio of lumpy particles and porous structure.

纳米结构磷酸锰铵水合物作为锂离子电池负极的合理设计

摘要 目前，多维尺度可控制备能源纳米材料是实现高性能的重要策略。为了解决这些问题，分别通过室温下的简易固相反应和共沉淀法设计和制造了纳米结构的块状颗粒和磷酸铵锰水合物（NMP）薄片。当首次用作 LIB 的负极时，与薄片 NMP 相比，块状颗粒表现出更好的电化学性能，例如更高的放电容量、更好的循环稳定性和倍率性能。例如，块状颗粒 NMP 电极在 350 次循环后在 100 mA g-1 下提供 1307 mAh g-1 的高可逆比容量，而另一个 NMP 电极仅提供一半。
