Lithium ions intercalation into the laser-exposed nanodisperse ТiO2 had been analyzed and its research results are given. The modes of laser treatment, when the degree of the «quest» load and, accordingly, specific energy capacity of the proper electrochemical current sources achieves a maximum, are experimentally set. Thermodynamical pecularities of current forming and lithium ions intrusion into the cathode material are set. Electrochemical source discharge capability analyzed in scope of laser-exposed ТiO2 using.
