Project title, type and project number

OPUS 24 Project No. 2022/47/B/ST5/03077 entitled “High-Performance Nano-Structural Electrode Materials for Li-S battery ”, 18/2024

Project leader

Dr hab. Piotr Pieta, prof. IChF PAN


Lithium-sulfur (Li-S) batteries are a promising candidate for next-generation energy storage systems due to their high theoretical energy density (2600 Wh kg-1), low cost, and environmental friendliness. However, the problems related to the electrode processes at the cathode of these batteries, namely the dissolution of the polysulfides (LiPSs) and the shuttle issues, cause a severe deterioration in efficiency, hindering their practical use. The present project aims to investigate multi-functional materials that can firmly trap LiPSs and accelerate the kinetics of the LiPSs redox reaction. Our strategy will be constructing an interconnected 3D network with high porosity built of a well-conducting skeleton with surface-immobilized active sites for effective trapping and converting LiPSs to Li2S.
The electrocatalytic properties of these nanostructured materials, tested by cyclic voltammetry (CV), linear sweep voltammetry (LSV), multi-cycling galvanostatic charging/discharging, and electrochemical impedance spectroscopy (EIS), will be correlated with (i) AFM imaging in PeakForceQNM and Kelvin probe mode, and (ii) microgravimetric measurements using electrochemical quartz crystal microbalance (EQCM). Additionally, DFT calculations will support the experimental studies explaining structure-reactivity correlation in Li-S batteries.
