High-performance lithium-ion batteries (LIBs) and sodium-ion battery (SIBs) anode materials Co 3 S 4 –ZnS/NC are prepared by carbonization and subsequent sulfidation using Co, Zn-based zeolitic imidazolate frameworks (ZIF) as a precursor. ZnS and Co 3 S 4 in-situ doping on polyhedral carbon framework, which enhances the conductivity and can buffer the volume expansion during the cycle and improve...
Despite its predominant role in controlling the functional properties, a longstanding concern in the research of ultrathin amorphous carbon and its hybrid materials is the inadequate understanding of their structural properties, especially on ceramic substrates. This constitutes a barrier for many technological developments. Here we comprehensively examine the structural properties of ultrathin carbon...
Hydrogen adsorption isotherms of activated carbon and its mixture with platinum coated activated carbon under various electric potentials and hydrogen pressures were measured at ambient temperature. Results indicated that electric potential enhanced hydrogen adsorption. The higher the applied electric potential is, the higher the hydrogen adsorption capacity is in the experimental range of 0–3000V...
