Microstructure Engineering Towards Porous Carbon Materials

James Alexander

For desired energy storage and conversion applications, microstructure regulation is crucial for carbon-based materials. In this, we report the microstructure designing towards permeable carbon materials from a similar forerunner empowering numerous energy stockpiling applications. One biomass waste of peanut dregs can yield graphenelike carbon materials (GLCMs) and highly disordered carbon materials (HDCMs). The asresulted HDCMs have a high hydrogen uptake of 3.03%, a high specific capacitance of 449 F g1 at a current density of 0.5 A g1, outstanding rate capability, and remarkable cycling performance due to their disordered structure, ultrahigh surface area, and relative small pore size. Due to their high graphitization, lamellar structure, and predominant mesoporosity, the resulting GLCMs have a reversible capacity of 731 mAh g-1 at a current density of 100 mA g-1 and excellent cycling stability as anode materials for LIBs. Based on these findings, it can be concluded that this method of microstructural engineering is both effective and promising for the design of porous carbon materials and their controllable preparation for a variety of desirable energy storage applications.
