Background. Despite a large volume of lithium ion accumulators production, the urge to increase their efficiency and reduce costs is still very topical. It should be noted that one of the main problems in creation of positive electrodes based on the lithiumized manganese oxide compounds with the highest characteristics is a lack of reliable, available and cheap technologies of production of materials with capability to make a reverse lithium ion intercalation that in turn will bring an increase in specific reservoir, expansion of the range of tension of cycling, and also reduction of material degradation in case of long cycling. The purpose of the work is to make a research of kinetics and a mechanism of the joint electrochemical intercalation of lanthanum and fullerene from nonaqueous fluoride containing solutions in MnO2-electrode before it is lithiumized; and to define kinetic regularities and a mechanism of increasing capacitor characteristics, modified by fullerene and fluo-ride-ions of LixLayMn1–yO2.
