Research on how synthesis of highly interfacial conductive and redox-active composite structures can resolve the low power density of batteries.
In order to effectively manage trash and preserve the ecological balance, biowaste can be converted into useful resources carbon material for energy storage devices. However, as seen from our earlier research, the biowaste-derived carbon (BWAC) typically has big pores (>1 m), which are not very interesting for applications involving energy storage. The most effective pores for charge storage are in the micro- to mesopore range, albeit this varies as material coating thickness rises. On the other hand, the existence of large pores (>1 m) causes both the density of charge adsorption and the loss of active mass. An appropriate electrode material for charge storage devices might be created by hierarchically filling the larger pores of BWAC with micro and mesoporous materials. Metal-organic frameworks (MOFs), a recently discovered material type, are extremely porous and provide tunable, well-defined porosity in the micro and meso ranges. Due to their strong redox activity, quick electron transport through redox dopant, and tunable electrolyte diffusion, MOFs are an appropriate filler for the BWAC and can therefore help to improve the state of energy storage devices.
Vishal Shrivastav earned his PhD in Material Science from the Academy of Scientific and Innovative Research, India, in February 2022. Thereafter, he joined the Regional Centre of Advanced Technologies and Materials, Czech Republic, for his postdoctoral research until July 2022. In October 2022, he was awarded the Green talent Award 2022. Currently, he is working as an assistant professor under the PASIFIC Programme at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw.
