Abstract

Organically synthesized porous carbon (OSPC-1) has a high lithium uptake of 748 mA h g-1, demonstrating that it is a strong contender as an anode material for lithium-ion batteries. Simulations of the lithium uptake on models generated of OSPC-1 gave values close to the experimentally obtained data. Thus, we assess the potential of OSPC-1 for use as an anode material in batteries of sodium, potassium, magnesium, and calcium. We find ion uptakes of 770, 386, 158, and 774 mA h g-1 for Li+, Na+, K+, and Ca2+, respectively. We also study the diffusive capabilities of ions through the OSPC-1 structure via means of active diffusion. The lithium ions were able to diffuse at a greater rate, followed by the divalent ions, Mg2+ and Ca2+, and the monovalent ions, Na+ and K+. All these ions were able to diffuse completely through the OSPC-1 structure with the diffusion rate being dependent on the ionic radius of the ion, coupled with the valency of the ion. Therefore, we show that OSPC-1 also has great potential as an anode material for Na+, K+, Mg2+, and Ca2+ batteries.
