要旨

Rechargeable aluminum batteries (RABs) with uniquely high energy-to-price ratios are promising energy storage systems. However, owing to the large-size active ions (e.g. AlCl4− and [AlCl2(urea)2]+) in state-of-the-art ionic-liquid RABs, the discharge–charge process usually encounters severe steric hindrance on electrodes, resulting in insufficient active-site utilization with limited practical capacity, and sluggish ion-diffusion kinetics with inferior rate-performance. Herein, to overcome these intrinsic confinements from the large-size active ions, we proposed, for the first time, a structure-rotatable cathode (quinone-based calix[4]quinone (C4Q)) for RABs with highly reduced steric hindrance, which is further verified via density functional theory (DFT) simulations. The newly applied C4Q cathode achieves one of the highest energy densities (480 W h kg−1 at 0.1 A g−1), enhanced rate capacity (81 mA h g−1 at 1.0 A g−1), and long-term stability (102 mA h g−1 at 0.2 A g−1 after 500 cycles) in RABs. Furthermore, the reaction mechanism of this rotatable cathode is revealed in detail via a series of characterization studies and corresponding DFT simulations. Overall, this new family of rotational organic materials will provide a new direction for promising high-performance RABs.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
