Harnessing Carbon‐Containing Materials for Next‐Generation High‐Temperature Electromagnetic Wave Absorbers

Carbon Energy, EarlyView.
Traditional carbon materials show limited high‐temperature oxidation resistance, which becomes pronounced above 673 K and significantly restricts their practical applicability. To address this challenge, enhancing polarization loss and leveraging its negative temperature dependence to offset the temperature‐induced increase in conductance loss are ...

Purification of Li2CO3 Obtained through Pyrometallurgical Treatment of NMC Black Mass from Electric Vehicle Batteries

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...
