Production of high-power cathode materials for Li-ion batteries

Production of high-power cathode materials for Li-ion batteries using a suitable spray technique

 

The dissertation project of Evgeny Legotin aims to adapt the spray roasting process for the production of the NMC (lithium nickel manganese cobalt oxide) compound as a cathode material for lithium-ion batteries.

 

Commercial NMC materials are nowadays manufactured by multiple-step methods (e.g. sol-gel processes), which account for long processing times and high production and operation expenses. In this project, the production of NMC electrode materials should be simplified and the number of technological steps should be reduced. The desired materials will be produced both in the lab scale as well as in an industrial spray roasting pilot plant, followed by their comprehensive physicochemical and electrochemical characterization.

 

The project is conducted as a cooperation between the AIT Austrian Institute of Technology GmbH (Center for Low-Emission Transport) and TU Wien (Institute of Chemical, Environmental and Bioscience Engineering).
