要旨

Instability caused by lithium dendrites and low oxidation potentials hinders the commercialization of poly(ethylene oxide) (PEO) based all-solid-state lithium metal batteries (ASSLBs). Herein, fluorinated carbon nitride (FCN) with a hierarchical porous structure was designed and fabricated to modify a PEO-based electrolyte. The resultant FCN effectively suppressed the lithium dendrite growth in ASSLBs and elevated the oxidation potential of the PEO-based electrolyte to as high as 5.2 V. The fluorine and nitrogen in the FCN resulted in the formation of a LiF- and Li3N-rich composite solid electrolyte interface (SEI) that prevented continuous side reactions between the Li metal anode and the electrolyte. The produced hierarchical structure has abundant mesopores, which provided fluent channels for Li ion diffusion without extra resistance and greatly promoted the cycling and rate performance of the batteries. By using this porous FCN modified electrolyte, Li–Li symmetrical cells exhibited an ultra-long lifespan of more than 2500 h at a current density of 0.1 mA cm−2. The ASSLBs combined with a high-voltage ternary cathode can work stably at high rates of 2C and 5C with capacity retentions of 87.8% after 150 cycles and 92.1% after 50 cycles, respectively. This work presents a facile and effective strategy for the design of polymer based electrolytes for high-voltage, high-rate ASSLBs.

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
