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.

Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. times above that of sodium-ion batteries with graphite electrodes.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Most importantly, after full conversion of the formate, the bicarbonate solution may be recharged with hydrogen to close the cycle. Bicarbonates are a component of many natural stones and are also commonly used as baking powder or sherbet (sodium bicarbonate, NaHCO 3 ). formed in the dehydrogenation.
