要旨

In the studies of supercapacitors (SCs), most efforts are focused on improving their electrochemical performances. However, in order to further promote SCs as widely used and reliable power supplies for electronics, how to charge them more effectively and conveniently should be considered. This work demonstrates a universal in situ charging strategy based on planar interdigital SCs. This strategy can be applied to different kinds of SCs without complicating them or obviously increasing their volumes. In situ charging was realized by simply adding a piece of Zn foil to one electrode of the SC and then the electrodes play a dual role as both a SC and a chemical cell. A carbon nanotube (CNT) electrode modified with silicone rubber can form a stable metal–air cell with Zn foil to charge the SC in situ. The charging process is activated when a drop of solution/water is added between the Zn anode and carbon cathode. The SC can be in situ charged to 1.0 V and its energy density is 3.92 μW h cm−2 based on the whole device, including the cell part. The SC can be charged repeatedly and higher voltage is attainable when several SCs are assembled into a compact one. To extend its feasibility, charging the SC with moisture is also demonstrated.

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
