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.

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.

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. Charged spoke with Steve Cotton, CEO and President, and David Regan, VP of Commercial, about the different ways to recycle batteries, and the challenges of building a full-scale circular supply chain for batteries.

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 But the necessity of catalysts has been argued, because the catalyst on carbon may not be able to work once its surface is blocked. For comparison, they built a Li?O O 2 batteries.In
