Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. to enlarge the interlayer lattice distance to accomodate the larger sodium ions.

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. Wenzel et al.

Researchers use in situ NMR spectroscopy to provide insight into silicon expansion in Li-ion batteries

Green Car Congress

A major barrier to the use of high energy capacity silicon in a lithium-ion battery is the volumetric expansion of silicon under lithiation and delithiation, which results in electrode degradation and capacity fade. Using this technique will help make battery design much more systematic, and less trial and error. Earlier post.)

Researchers propose new VO2 cathode material for aluminum-ion rechargeable battery

Green Car Congress

Schematic representation of the super-valent battery during charge/discharge process. A team from the University of Science and Technology Beijing is proposing a new super-valent battery based on aluminium ion intercalation and deintercalation. Herein, we define this kind of battery as super-valent battery.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Potassium will just zoom in and zoom out, so you can have an extremely high-power battery. A team at Stanford led by Prof. —Yi Cui.

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.
