The Li‐CO2 battery has great potential for both CO2 utilization and energy storage, but its practical application is limited by low energy efficiency and short cycle life. Efficient cathode catalysts are needed to address this issue. Herein, this work reports on molecularly dispersed electrocatalysts (MDEs) of nickel phthalocyanine (NiPc) anchored on carbon nanotubes (CNTs) as the cathode catalyst...
Rational synthesis of flexible electrodes is crucial to rapid growth of functional materials for energy‐storage systems. Herein, a controllable fabrication is reported for the self‐supported structure of CuCo2O4 nanodots (≈3 nm) delicately inserted into N‐doped carbon nanofibers (named as 3‐CCO@C); this composite is first used as binder‐free anode for sodium‐ion batteries (SIBs). Benefiting from the...
A series of rod‐like porous graphitic‐carbon nitrides (short as CNs) with enhanced in‐plane ordering have been fabricated through self‐assembled heptazine hydrate precursors for the first time. By controlling the calcination of the preformed precursors with different temperature‐rising rates, the resulted CNs (SAHEP‐CNs‐1) with the most ordered and least stacked graphitic planar are showing a tremendously...
A flexible carbon membrane composed of ultrasmall transition metal oxides is fabricated by L. Jiao and co‐workers on page 4865. In the cover image, the fishing net represents a carbon matrix, which effectively facilitates ionic/electron diffusion kinetics. CuO quantum dots in the carbon frame could tolerate the absolute strain during Na+ insertion and extraction process. Particle size, carbon content...
The design of sodium ion batteries is proposed based on the use of flexible membrane composed of ultrasmall transition metal oxides. In this paper, the preparation of CuO quantum dots (≈2 nm) delicately embedded in carbon nanofibers (denoted as 2‐CuO@C) with a thin film via a feasible electrospinning method is reported. The CuO content can be controlled by altering the synthetic conditions and is...
