The rational construction of efficient bifunctional oxygen electrocatalysts is of immense significance yet challenging for rechargeable metal-air batteries. Herein, this work reports a metal-organic framework derived 2D nitrogendoped carbon nanotubes/graphene hybrid as the efficient bifunctional oxygen electrocatalyst for rechargeable zinc-air batteries. The as-obtained hybrid exhibits excellent catalytic activity and durability for the oxygen electrochemical reactions due to the synergistic effect by the hierarchical structure and heteroatom doping. The assembled rechargeable zinc-air battery achieves a high power density of 253 mW cm −2 and specific capacity of 801 mAh g Zn −1 with excellent cycle stability of over 3000 h at 5 mA cm −2 .Moreover, the flexible solid-state rechargeable zinc-air batteries assembled by this hybrid oxygen electrocatalyst exhibits a high discharge power density of 223 mW cm −2 , which can power 45 light-emitting diodes and charge a cellphone. This work provides valuable insights in designing efficient bifunctional oxygen electrocatalysts for long-life metal-air batteries and related energy conversion technologies.

The development of efficient electrode materials is a cutting‐edge approach for high‐performance energy storage devices. Herein, an effective chemical redox approach is reported for tuning the crystalline and electronic structures of bimetallic cobalt/nickel–organic frameworks (Co‐Ni MOFs) to boost faradaic redox reaction for high energy density. The as‐obtained cobalt/nickel boride/sulfide exhibits a high specific capacitance (1281 F g−1 at 1 A g−1), remarkable rate performance (802.9 F g−1 at 20 A g−1), and outstanding cycling stability (92.1% retention after 10 000 cycles). An energy storage device fabricated with a cobalt/nickel boride/sulfide electrode exhibits a high energy density of 50.0 Wh kg−1 at a power density of 857.7 W kg−1, and capacity retention of 87.7% (up to 5000 cycles at 12 A g−1). Such an effective redox approach realizes the systematic electronic tuning that activates the fast faradaic reactions of the metal species in cobalt/nickel boride/sulfide which may shed substantial light on inspiring MOFs and their derivatives for energy storage devices.

“…The energy density and power density of the device is summarized in the Ragone plot of Figure 6f, which shows a high energy density of 17.13 Wh kg À 1 at the power density of 900 W kg À 1 , and much higher than other previously reported materials such as ANCLCNFs, [35] NFMCNFs, [36] C-blank, [37] Z-HPAC, [38] CLCNF/PANi, [39] HGPC-A, [40] N,S-GLC, [41] NPCs [42] and other carbon materials related symmetrical devices. [44] In contrast, the energy density of the device in KOH solution is only 7.15 Wh kg-1, which is less than half that in Na 2 SO 4 solution, and smaller in H 2 SO 4.…”

The pore structure control of porous carbons, especially ultramicroporous carbons, has long been a great challenge, and it is desirable to propose new strategies to deal with this dilemma. Herein, we designed and obtained ultra-microporous dominant porous carbon materials (UMC-IPNs) with an unimodal pore diameter of 0.6 nm by the strategy of interpenetrating polymer networks precursor carbonization. Thanks to the intertwining characteristics of the two interpenetrating polymer networks, the microphase separation which often occurs between the polymers is well suppressed, and also the pores of the as-obtained ultra-microporous carbons are interconnected. The calculated specific surface area is 1551 m 2 g À 1 . Furthermore, as electrode material, UMC-IPNs has been confirmed to have exceptional electrochemical performance (the specific capacitance is 268 F g À 1 at 0.5 A g À 1 , and after 10,000 cycles, the capacity is 96 % of the original at 6 A g À 1 ) and rapid electrochemical kinetics (the surface capacitance effect ratio is about 85.4 % in our calculation results). In addition, ultra-microporous carbons are interesting for other applications such as gas capture, catalysis, and sensor technology.
