Na, K and Mg-ion batteries (NIBs, KIBs and MIBs) have drawn considerable interest due to their high abundance and excellent safety. However, the lack of high-performance anode materials is a...
Lithium-ion batteries have long been the focus of energy
storage.
The potential application of carbon-derived structures as lithium-ion
battery anodes was examined using the first-principles density functional
theory approach. The results of our calculations revealed that the
modified lattice constant, structure, and parameters are similar to
those found in earlier research. It is worth noting that the twin-graphene
double layer has several stable adsorption sites for lithium. Meanwhile,
we discovered that the characteristics of semiconductors of pristine
twin-graphene changed into metal properties after absorbing lithium.
From climbing image nudged elastic band calculations, we got a medium
diffusion barrier of 0.42 eV for lithium ion on twin-graphene, which
denotes strong diffusivity. Therefore, it has an ultrahigh theoretical
capacity of 3916 mAh/g, about 5 times that of graphene (744 mAh/g).
Twin-graphene double-layer lithium-ion batteries have an average open
circuit voltage of 0.32 V, which ensures long service life and quick
charging in practical applications. The relatively good conductivity
and stability of the twin-graphene double layer are further demonstrated
throughout the charge–discharge operation. By reason for the
foregoing, twin-graphene double layers will be excellent battery anodes
that can be applied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
