Sodium-ion Batteries with Functional Materials (So FuN). KU Leuven
State-of-the-art
Lithium ion battery technology is the most established and widely used in portable electronic devices and electric vehicles. With limited lithium resources available, sodium ion batteries are gaining interest recently thanks to the abundance and relatively low cost. The gravimetric and volumetric density of Na-ion batteries would not exceed Li-ion batteries (Fig.1) 1 because of the relatively heavier, larger ...
