In recent decades, DFT has been increasingly employed to simulate the structures and elucidate the activities of energy storage materials, and the predominant functionals applied in battery materials science are the GGA functionals, especially the Perdew–Burke–Ernzerhof (PBE) GGA.
In the electrochemical reactions of battery materials, the adsorption of ions plays a key role on the reactivity of the electrode materials, so the adsorption kinetics has great influence on the capacity and cycling performance of batteries.
The value of Adsorption energy they found is −1.4 eV for the adsorption of lithium. This negative value is favorable for the adsorption of metal atoms on monolayer B 3 S. It was concluded that the negative value of adsorption energy plays its role in Li ion batteries .
In addition, the adsorption capacity of Li 2 S also shows a similar adsorption trend. In subsequent diffusion studies, it was found that the surface of CoP exhibits the lowest energy barrier, indicating that CoP has the fastest diffusion behavior. In Li–S batteries, S@rGO/CoP also showed the best rate performance and cycle stability.
According to the reaction nature (whether a new substance is formed during the sorption process), adsorption can be divided into two types: physisorption and chemisorption [26, 27]. Physisorption is related to the intermolecular force (known as the van der Waals force) between adsorbents and adsorbates .
The greatest adsorption of metal atoms was reported to be 0.67 eV, 0.76 eV, and 0.76 eV for Na, Li, and Mg respectively, for B1 site as shown in Table 2 . Saibal Jana et al. investigated B 3 S monolayer for the anode material in case of increasing demand of renewable energy resources.
