Oznake: sodium-ion batteries;non-graphitizable carbons;sodium storage mechanism;organic precursor;closed porosity;pore filling;heteroatom doping;bismuth(III) sulfide;nanoparticles;
Sodium-ion batteries (SIBs) are the frontrunner to displace lithium-ion batteries (LIBs) in stationary storage applications, due to sodium’s abundance and even distribution around the globe, consequently reducing the strain on lithium resources. Non-graphitizable carbons are currently utilized as ne ...
