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

open access: yesChemSusChem, 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 ...

Comparison of Diesel Engine Characteristic Using Pure Coconut Oil, Pure Palm Oil, and Pure Jatropha Oil as Fuel [PDF]

open access: yes, 2009
Diesel engine can be operated on either pure plant oil (PPO) oil or biodiesel. Biodiesel production process is expensive due to many stages of processes, while PPO has a lower cost of production, lower energy consumption, and simpler process.
