| 英文摘要 | sluggish kinetic characteristics of the electrode reactions and low electrode space utilization for solid li2o2 deposition are limiting factors for li-o-2 batteries. in this work, iron-/cobalt-doped micron-sized honeycomb-like carbon (fe-mhc, co-mhc) with a hierarchical pore structure is prepared by using nano-caco3 as a template. the effect of the transition-metal nanoparticles as a second template on further pore construction and optimization is presented. as graphitization catalysts, the added transition metals also affect the formation of the graphene-rich structure in the carbon framework. as a result, the obtained hierarchical carbon materials doped with trace metals exhibit higher electrochemical catalytic activity and stability than non-doped samples. in particular, an enhanced discharge capacity as high as 9260 mahg(-1) is achieved for the fe-mhc cathode, which is attributed to its enlarged pore volume and high utilization of the electrode space. |
