Single-atom cobalt electrocatalysts for foldable solid-state Zn-air battery
Abstract
Abstract To achieve wearable application, developing highly active and low cost non-precious metal bifunctional oxygen catalysts for foldable solid-state Zn-air battery is still a great challenge. Herein, we report a single-atom cobalt electrocatalyst with CoN4 moieties dispersed on nitrogen-doped graphitic nanosheet (marked as CoN4/NG) by a surfactant-assisted approach. The CoN4/NG catalyst exhibits excellent electrocatalytic activities with a half-wave potential of 0.87 V (versus RHE) for ORR and a low overpotential of 0.38 V at 10 mA cm−2 for OER. Moreover, the liquid Zn-air battery with the CoN4/NG catalyst as the air electrode displays a superior discharging and charging performance, larger power density, higher energy density and robust stability (without any decay after 100 h cycle test), compared to the 20% Pt/C + IrO2 counterpart. Importantly, the CoN4/NG-based flexible solid-state Zn-air battery also exhibits a high power density and a long-term stability of 30 cycles under flat and folded states, which means that the single-atom cobalt catalyst may be a promising candidate for practical applications in wearable flexible solid batteries.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
