Researchers improve the performance of sodium-ion batteries by using tailored carbon anodes with hierarchical porosity

Green Car Congress

Researchers at Justus Liebig University, Giessen, Germany, have improved the performance of sodium-ion batteries ( earlier post ) by using tailor-made carbon materials with hierarchical porosity for the anode instead of common carbon-based anode materials. Advance Article doi: 10.1039/C1EE01744F. Performance of the new anodes.

Debunking the Lithium "Mining" FUD

Plug In India

Team PluginIndia The Lithium mining FUD (Fear, Uncertainty, Doubt) created by some paid media organizations and random YouTube channels is so bad, that many people read headlines of such articles and assume that Lithium mining is the worst thing in the world and is worse than extracting and refining 10,000 liters of oil used by an average ICE car.

Ningbo researchers propose mixed-ion Li/Na batteries

Green Car Congress

Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.

The shelf-life of stored charge in rechargeable devices does not scale linearly with maximum SP and has led to trends referred to as ‘range-anxiety’, ‘compulsive charging’, etc. Towards this goal, we present for the first time in this article a membrane that can regulate transmembrane ion transport as a function of its redox state.

However, it also possible to separate and manipulate a few connected layers of graphene giving a material researchers refer to as few-layer graphene (FLG). Graphene is a single, one-atom-thick layer of the mineral graphite (an allotrope of carbon). A cross section of the silicon and FLG together in an anode.
