UP Catalyst CO2-derived carbon nanotube electrode material boosts cycle life in Na-ion batteries

Green Car Congress

Tests conducted by Titirici Group , a multidisciplinary research team based at Imperial College London, have found that a novel carbon nanotube electrode material derived from CO 2 —produced by Estonian nanotech company UP Catalyst ( earlier post )—enhances the cyclability of sodium-ion batteries. From every 3.7

CATL introduces first generation of sodium-ion batteries; up to 160 Wh/kg; targeting >200 Wh/kg with Gen 2

Green Car Congress

(CATL) unveiled its first-generation sodium-ion battery, together with its AB battery pack solution—which is able to integrate sodium-ion cells and lithium-ion cells into one pack. The sodium-ion battery has a similar working principle to the lithium-ion battery; sodium ions shuttle between the cathode and anode.
