It is shown that titania which is obtained from the titan tetrachloride by a partial sour hydrolysis using muriatic acid, is intercalated by lithium ions to high values of the "host" loading (x = 5,5-7,5) that is the reason of high specific-capacitance of the researched electrochemical system ( 2600 mAohour/g ). It is set that the high value of x during the intercalation of Li+ in TiO2 is provided by the fact, that it has X-ray amorphous composition with structural features of anatase. The laboratory standards of galvanic elements with specific capacity 1,224 o 107 A o s/kg and specific energy 3,06 o 107 W o s/kg are created by intercalation technologies on the base of obtained and modified nanodispersed TiO2. The biggest capacity during electrochemical intercalation of lithium atoms in the host-material is demonstrated by X-rat amorphous H-titan which has the layer structure. Mentioned N-titan is perspective for the using as cathode material of lithium galvanic power sources. Technological conditions and modes of the heat treatment of plant raw materials are determined. During the heat treatment porous carbon material (PCM) is obtained. PCM is suitable for the condenser systems formation, which works on the principle of charge/discharge of Double Surface Electric Layer. So these conditions are the followings: carbonization of raw material and activating of PCM takes place at temperatures 1100-1150 K and pressure of 0,6-0,8 MPa with the use of aquatic steam and linked water as porouscreator. On the basis of analysis of Nyquist diagrams mechanisms of passing the electrochemical processes in the condenser systems on the basis of laser radiation-exposed PCM are suggested. In particular, in the negative area of potentials a high-frequency arc corresponds to Faradeic, midfrequency part of Nyquist diagram represents the process of different row complexes disintegration and designed by the Gerisher impedance and low-frequency part corresponds to the charge of Double Surface Electric Layer.
