Antimony nanocrystals as high-capacity anode materials for both Li-ion and Na-ion batteries

Green Car Congress

The data for 10 nm Sn (tin) NCs are shown for comparison. Initial studies revealed that antimony could be suitable for both rechargeable lithium- and sodium-ion batteries because it is able to store both kinds of ions. 20C (1C = 0.66 1 , 9 cycles at each C-rate, first cycle at 0.1C).

V), which contributes to the low rechargeability. contrast with LiO 2 and NaO 2 , KO 2 is thermodynamically stable and commercially available. Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. For comparison, they built a Li?O O 2 batteries.In —Ren and Wu.

Sulfur–TiO2 yolk-shell cathode for Li-sulfur battery shows best long-cycle performance so far

Green Car Congress

C, in comparison with bare sulfur and sulfur–TiO 2 core–shell nanoparticles. However, many challenges remain in developing a practical lithium–sulphur battery for commercialization. The sulfur cathode stored up to five times more energy per sulfur weight than today’s commercial materials. Click to enlarge. Click to enlarge.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

In a review paper in the journal Nature Materials , Jean-Marie Tarascon (Professor at College de France and Director of RS2E, French Network on Electrochemical Energy Storage) and Clare Gray (Professor at the University of Cambridge), call for integrating the sustainability of battery materials into the R&D efforts to improve rechargeable batteries.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The scientists found the nanofluids could be used in a system with an energy-storing potential approaching that of a lithium-ion battery and with the pumpable recharging of a flow battery.
