Anode materials for lithium-ion batteries: A review
Graphite is the most widely used anode material for Li-ion batteries and is also considered a promising anode for K-ion batteries. However, Na +, a similar alkali ion to Li + or K +, is incapable of being intercalated into graphite and thus, graphite is not considered a potential electrode for Na-ion batteries. ...
Na-organic batteries are a promising candidate for grid-scale energy storage due to the abundance of Na and absence of transition metal elements. However, the shuttle effect of soluble redox-active organics induces low coulombic efficiency and fast capacity decay, especially collocated with the highly reacti
