Towards the production of oxalate precursors from NMC111 black mass via selective leaching of Li and Al and solvent extraction of Cu
A novel recycling route for spent lithium-ion batteries has been investigated. The end goal is to produce cathode active material (CAM) precursor directly from the recycled solution. The process begins with an oxalic acid leaching (0.6 M H2C2O4, 60 °C, 120 min, and S/L = 50 g/L), where Li is…

A physics-based recursive transmission line model for impedance of the cathode catalyst layer in operating PEM fuel cells
We derive a recursive transmission line model (TLM) for the cathode catalyst layer impedance in a working PEM fuel cell. The TLM results from the approximate solution of the macro-homogeneous model equations for impedance of the CCL with fast oxygen transport and a finite proton transport rate. The…
