Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. The sodium salt makes up the cathode; the anode is made up of phosphorous.

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).

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Metal hydride tanks store hydrogen in a relatively manageable volume but are very heavy and expensive, as well as operating only at high temperatures or far too slowly. The nontoxic aqueous solution of formate is easily stored and transported. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2.

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.

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. To prepare the material, the team reacted sodium thiosulfate with hydrochloric acid to create monodisperse sulfur nanoparticles (NPs); these NPs were then coated with TiO 2 , resulting in the formation of sulfur–TiO 2 core–shell nanoparticles. —Yi Cui.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). The battery in her EV is a variation on the flow battery , a design in which spent electrolyte is replaced rather than recharged. The recharging could also be done at a service station or in the EV itself.
