It is modified matrix of anatase in turn of the thermal and laser treatments. Thedependence of Gibbs energy change of the intercalation reaction of lithium with the guest loaddegree change was analyzed. Laser irradiation turned out to increase twice the value of maximumlithium “guest” loading, constricting heterophase area and changing contrarily concentrationgenesis of temperature dependence of entropy of lithium dilution. The optimal conditions of laserirradiation nanodispersive anatase (pulse energy E = 0,02 J, pulse duration τ = 15 ns repetitionfrequency f = 28 Hz, duration of exposure to 5 min.), at which specific energy characteristics of LPS,formed on its basis, increased by 55% is set
