The multishelled (Co Mn )(Co Mn )2O hollow microspheres with controllable shell numbers up to septuple shells are synthesized using developed sequential templating method. Exhilaratingly, the septuple-shelled complex metal oxide hollow microsphere is synthesized for the first time by doping Mn into Co O , leading to the change of crystalline rate of precursor. Used as electrode materials for alkaline rechargeable battery, it shows a remarkable reversible capacity (236.39 mAh g at a current density of 1 A g by three-electrode system and 106.85 mAh g at 0.5 A g in alkaline battery) and excellent cycling performance due to its unique structure.
采用发展起来的顺序模板法合成了具有多达 7 个壳层的可控壳数的多壳（CoMn）（CoMn）2O 中空微球。令人振奋的是，首次通过在 CoO 中掺杂 Mn 合成了 7 壳层复杂金属氧化物中空微球，导致前驱体的成核速率发生变化。作为碱性可充电电池的电极材料，它表现出显著的可逆容量（在三电极系统中电流密度为 1Ag 时为 236.39mAhg-1，在碱性电池中 0.5Ag 时为 106.85mAhg-1）和优异的循环性能，这归因于其独特的结构。
