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. prepared a carbon material with interconnected pores in two size ranges.

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.)

UNSW team demonstrates high reversible hydrogen storage capacity under mild conditions for sodium borohydride using novel core-shell nanostructure; potential for vehicles

Green Car Congress

A team from the University of New South Wales (Australia) reports on a novel core-shell strategy leading to high and stable hydrogen absorption/desorption cycling for sodium borohydride (NaBH 4 ) under mild pressure conditions (4 MPa) in an open-access paper in the journal ACS Nano. With a high storage capacity (10.8

Fraunhofer holding 3rd annual workshop on Li-sulfur batteries in November

Green Car Congress

Fraunhofer says that Lithium-sulfur batteries are the most promising choice for future energy storage systems, with novel materials such as nanostructured carbon/sulfur composite cathodes, solid electrolytes and alloy-based anodes expected to enhance significantly the cell’s performance.

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.

Tsinghua researchers conclude surging lithium price will not impede EV boom

Green Car Congress

From December 2020 to April 2022, the Chinese spot market has seen a price increase by 830% for lithium carbonate, 100% for cobalt sulfate, and 60% for nickel sulfate, with their per-ton prices rising to $73,000, $18,000, and $7,000, respectively. In comparison, only 40% of global oil supply clusters in the top 3 producing countries.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Pyrometallurgy, which traditionally doesn’t recover carbon or lithium, seems likely to be phased out. We take that black mass as the input to our process, which is then powered by 100% renewable, carbon-free energy. Other batteries are coming from battery energy storage systems. They need to contain them.
