Influence of carbon addition to sulphur cathode on Li-S cell operating parameters

Financing institution: NCN

Timeframe: 2017-2020

The project objective is to investigate the effect of adding porous carbon to a sulphur cathode in a Li-S cell.


Advanced technologies of manufacturing functional materials to conduct, process and store energy. (Field of action II) Semiconductive materials of the skutterudite structure applied as electrodes in lithium-ion cells and electric energy thermogenerators  (Action  II.3)         

The project is performed within: Operational Programme Innovative Economy
Timeframe: 2010-2014

The project concerns possible applications of materials having skutterudite structure (mainly CoSb3) in lithium batteries. Materials are obtained by conventional (sintering) or chemical methods. The latter yields nanometric granularity. Materials of this type could store great amounts of electric load, which makes them attractive as new anode materials.

Advanced materials and technology of their manufacture. (Field of action VI) Nanostructural composite conductive membranes as solid electrolytes in electrochemical lithium cells and PV cells. (Action VI.70)

The project is performed within: Operational Programme Innovative Economy
Timeframe: 2010-2014

The project consists in preparation of composite polymer-ceramic membranes and their application as electrolytes in lithium-ion and PV cells. This type of membranes could absorb liquid and change it into stable gel. So prepared gel electrolyte is highly conductive and evaporation of the solvent is limited, which make the gel electrolyte potentially attractive for safe lithium batteries.

Chemical synthesis and electrochemical properties of graphene and its nanocomposites.

The project is performed within: National Science Center (NCN)
Timeframe: 2012-2015

The aim of the project is to develop a synthesis method of graphene of high specific surface area, graphene oxide and new composites of graphene with metal oxides as TiO2, Fe2O3, Cr2O3, SnO2. The obtained composites will be examined as potential active materials in electrochemical energy storage and conversion devices: ultracapacitors and lithium batteries. The research will focus on preparation of materials of possibly the highest energy storage capacity.
