BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.

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.

Faradion demonstrates proof-of-concept sodium-ion electric bike

Green Car Congress

British battery R&D company Faradion has demonstrated a proof-of-concept electric bike powered by sodium-ion batteries at the headquarters of Williams Advanced Engineering, which collaborated in the development of the bike. Sodium-ion intercalation batteries—i.e., Oxford University was also a partner. Earlier post.)

V), which contributes to the low rechargeability. Potassium, an alkali metal similar to lithium (and sodium) can be used in a rechargeable battery. For comparison, they built a Li?O V), which renders the system with a low round-trip energy efficiency around 60%. O 2 batteries.In —Ren and Wu. Bender, Miloš Vra?ar,

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

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.

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.
