Abstract N-doped carbon encapsulated MnO nanoparticles (MnO/NC) is synthesized via a straightforward hydrothermal strategy and a subsequent annealing treatment. When evaluated as an anode for lithium ion batteries, MnO/NC exhibits a high reversible capacity (1158 mA h g−1 over 300 cycles at 0.2 A g−1), good cyclability, and excellent rate performance. The superior electrochemical performance should be attributed to the synergistic effect of MnO nanoparticles and N-doped carbon capsules.

用于增强锂存储的 N 掺杂碳包封的 MnO 纳米颗粒

摘要 通过简单的水热策略和随后的退火处理合成了 N 掺杂的碳包封的 MnO 纳米粒子 (MnO/NC)。当被评估为锂离子电池的负极时，MnO/NC 表现出高可逆容量（1158 mA h g-1，0.2 A g-1 下 300 次循环）、良好的循环性能和优异的倍率性能。优异的电化学性能应归因于MnO纳米颗粒和N掺杂碳胶囊的协同作用。
