Lithium-ion batteries (LIBs) are dangerous to recycle, as they pose a fire hazard when cut and contain various chemical hazards. If recycled safely, LIBs provide rich secondary source for metals such lithium cobalt, while reducing the environmental impact of end-of-life LIBs. Discharging spent in 5 wt.% NaCl electrolyte at room temperature enables their safe dismantling. A sludge was observed form during LIB discharging, with composition 34.9 Fe, 35 O, 17.7 Al, 6.2 C, 4.2 Na. The average...
Aluminum nitride (AlN) was produced via the combustion synthesis of loosely packed aluminum powder (pore fraction ∼0.8) in a graphite reactor that lined with permeable carbon felt. Almost‐complete conversion achieved forced flow nitrogen for beds 50‐150 mm deep (mass 200‐650 g). The product form aggregated bed, regions distinct morphology, and had predominantly whisker morphology. Some control over microstructure possible by changing processing parameters. addition 5% ammonia to resulted...
