Electrode materials with improved characteristics for lithium and sodium electrochemical power sources: progress and prospects (A review). D.P. OPRA, A.K. TSVETNIKOV, S.L. SINEBRYUKHOV, V.I. SERGIENKO, S.V. GNEDENKOV (Institute of Chemistry, FEB RAS, Vladivostok).
Scientific research for the improvement of electrochemical power sources has not stopped since their creation. Mainly, the efforts of scientists are aimed on improving the material of electrodes, which determines the electrochemical system and the mechanism of cell reaction. This review highlights briefly the results of scientific studies devoted to designing novel and advanced materials for electrodes of lithium and sodium electrochemical power sources, which were performed in the Institute of Chemistry of the Far Eastern Branch of the Russian Academy of Sciences. Achievements in synthesis of compounds (including organic and fluorine-containing) and composites with high energy density for primary and secondary lithium power sources are summarized. Advances in the development of improved electrode materials based on titanium dioxide nanostructures for safety lithium-ion batteries are described. The possibilities of using such nanomaterials as matrices for reversible insertion of sodium ions for sodium-ion batteries are discussed.
