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.)

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. One molar LiPF6 in ethylene carbonate/dimethyl carbonate mixture containing 3 wt % of FEC was used as electrolyte for Li-ion cells, whereas 1 M NaClO 4 in propylene carbonate containing 10 wt % of FEC was used for Na-ion batteries. 20C (1C = 0.66 V potential range.

OSU team demonstrates concept of potassium-air battery as alternative to lithium-air systems

Green Car Congress

Recently, researchers have also found out the instability of electrolyte and carbon electrode under the high charging potential (>3.5 V), which contributes to the low rechargeability. But the necessity of catalysts has been argued, because the catalyst on carbon may not be able to work once its surface is blocked. O 2 battery.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Researchers at the Leibnitz Institute for Catalysis (Rostock, Germany) have introduced a new approach to hydrogen storage that is based on simple salts of formic acid and carbonic acid. A fundamental problem with the use of these storage materials is the separation of the carbon dioxide formed when the hydrogen is released.

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.

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.

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.
