Thermal analysis of lithium ion battery cathode materials for the development of a novel pyrometallurgical recycling approach

Carbon Resources Conversion, 2021
Since pyrometallurgical approaches on lithium ion battery recycling are not yet capable of recovering lithium but only nickel, cobalt and manganese, the Chair of Thermal Processing Technology at the Montanuniversitaet Leoben started to investigate ...

Investigation of Potential Recovery Rates of Nickel, Manganese, Cobalt, and Particularly Lithium from NMC-Type Cathode Materials (LiNi_xMn_yCo_zO₂) by Carbo-Thermal Reduction in an Inductively Heated Carbon Bed Reactor

Metals, 2021
Within the e-mobility sector, which represents a major driver of the development of the overall lithium-ion battery market, batteries with nickel-manganese-cobalt (NMC) cathode chemistries are currently gaining ground. This work is specifically dedicated

A Novel Pyrometallurgical Recycling Process for Lithium-Ion Batteries and Its Application to the Recycling of LCO and LFP

Metals, 2021
The bottleneck of recycling chains for spent lithium-ion batteries (LIBs) is the recovery of valuable metals from the black matter that remains after dismantling and deactivation in pre‑treatment processes, which has to be treated in a subsequent step ...

Investigation of transient multiphase Taylor-Couette flow

Alexandria Engineering Journal, 2022
A multiphase, transient, horizontal, Taylor-Couette flow has been investigated numerically. This flow governs thermal performance of self-contained drum motor (SCDM) drive systems.

Cooling of a synchronous electric motor using an axial air flow

International Journal of Thermofluids, 2023
The current work investigates the rate of cooling of an axial air flow through the gap between the stator and the rotor of a four-pole synchronous electric motor. The axial air is passing though the rotor's four longitudinal slots.

A Combined Hydro-Mechanical and Pyrometallurgical Recycling Approach to Recover Valuable Metals from Lithium-Ion Batteries Avoiding Lithium Slagging

Batteries, 2022
Meeting the increasing demand for energy storage based on lithium-ion batteries (LIB) is not only a question of resource availability but also an issue of resource conservation and efficient recycling management.
