RFBR Project 18-29-04058-мк

(2019-2021)

The project is aimed at creating a new class of electrode materials for supercapacitors and high power batteries. It is proposed to use conducting metal-organic coordination polymers (MOCPs) with ligands capable of reversible oxidation / reduction as such materials. This will make it possible to obtain materials that have both a redox capacity and a double-layer capacity due to the high porosity of the ordered structures of the MOCP. The base cross-linking will be a flat-square nickel (II) complex with two chelating N, O-ligands providing a conjugated system of bonds between adjacent metal centers. The adjustment of the functional properties of such systems will be carried out by varying the core (organic framework) of the ligand, which will allow one to regulate both the geometry or dimension of polymers (1-D, 2-D or 3-D) and their redox properties due to the introduction into the ligand electroactive components. Such materials will be obtained for the first time, and their expected capacity, according to the analysis of preliminary experiments and literature data, may exceed 1300 F / g.
