Abstract


It is modified matrix of anatase in turn of the thermal and laser treatments. The dependence of Gibbs energy change of the intercalation reaction of lithium with the guest load degree change was analyzed. Laser irradiation turned out to increase twice the value of maximum lithium “guest” loading, constricting heterophase area and changing contrarily concentration genesis of temperature dependence of entropy of lithium dilution. The optimal conditions of laser irradiation nanodispersive anatase (pulse energy E = 0,02 J, pulse duration τ = 15 ns repetition frequency 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.
