General information

Title of the Project: Novel Polymer Electrolytes for Application in Lithium and Lithium-Ion Batteries

Project Acronym: BATLIT

Area of the Project: lithium-ion batteries, ion conducting electrolytes, lithium salts, polymer electrolytes

Summary: The project concerns the development of new polymer electrolytes (in the form of thin membranes) of increased share of cationic conductivity. In the hitherto studies, anions are the dominating electric charge carriers, which leads to unfavorable salt concentration gradient and worsening of the battery characteristics. Achieving an increase in the lithium cations transference numbers values assures the batteries a longer operation time, smaller decrease in capacity, and greater current densities. The obtaining of such type of electrolytes is one of the conditions of the development of lithium-ion batteries predicted for charging electronic devices, in hybrid car engines and in large devices for storing energy acquired from renewable sources, among others.
Within this project it is expected to increase the share of cation conductivity of lithium electrolytes by reactions of complexing salt anions with boron or aluminum compounds showing Lewis acid properties. In addition, an increase in the degree of salt dissociation, decrease in the share of ion associates and increase in cation mobility are expected, which should assure higher ionic conductivity. The utilization as aluminum receptors of aluminum carboxylates with incorporated oligoether substituents which, as appears from the studies of the Principal Investigator, are very efficient anion traps, is planned. As boron derivatives, compounds containing fluorine substituents will be obtained, which due to the strong induction effect, increase the deficiency of electrons on the boron atom.
The complex salts obtained will be applied as components of solid and gel polymer electrolytes. For selected electrolytes, studies will be carried out on their flame-retardant properties by introducing ionic liquids. Electrochemical characterization of the electrolytes obtained will cover determination of ionic conductivity and electrochemical stability, as well as determination of lithium cations transference numbers.

Funding source: Norwegian Financial Mechanism, Polish-Norwegian Research Programme, Small Grant Scheme 2012 which provides support for research projects implemented by women specializing in the area of technical sciences.

Norwegian Financial Mechanism and the European Economic Area Financial Mechanism, i.e. EEA and Norway Grants, are a form of foreign aid granted by Norway, Iceland and Liechtenstein to new UE Member States. The funds are connected with the Polish accession to the European Union and the simultaneous accession to the European Economic Area (EU + Iceland, Liechtenstein, Norway and Switzerland). Donor countries benefit from access to the internal market of the European despite the fact that they are non-EU members. Currently, the second edition of the grants is being implemented, it covers the period 2009-2014. The previous edition covered the period 2004-2009.
