Making Better Sodium-Ion Batteries
The performance of sodium-ion batteries can be markedly improved by substituting common carbon-based anode materials with a templated carbon featuring pores and channels on the micro- and nanometer scales, according to researchers in Germany (Energy Environ. Sci., DOI: 10.1039/c1ee01744f). Similarities between sodium- and lithium-ion electrochemistry coupled with sodium’s abundance relative to lithium have motivated researchers to develop experimental sodium-ion cells. Such batteries could provide a low-cost way to store electricity generated by wind turbines . . .
