Description A study on innovative separators is proposed that covers structural and morphological characterization along with the evaluation of the electrochemical performance of the separators in real battery systems. The research work will be carried out both in the research labs of the Electrochemistry Group (DISAT, Politecnico) and in the company where the separators are produced.
The separator is a critical component in liquid electrolyte batteries, and is placed between the positive electrode and the negative electrode to prevent physical contact of the electrodes while enabling free ionic transport and isolating electronic flow. It mostly is a microporous layer consisting of either a polymeric membrane or a non-woven fabric mat. Essentially, it must be chemically and electrochemically stable towards the electrolyte and electrode materials, and must be mechanically strong to withstand the high tension during the battery assembly operation. Structurally, the separator should have sufficient porosity to absorb liquid electrolyte for the high ionic conductivity.
