The object of investigation - electrode materials for lithium chemical power sources. The aid of the work - developing new anode materials for lithium-ion batteries by over-stoichiometric intercalation of lithium into cathode materials. It has been determined that at over-stoichiometric intercalation of lithium into LiCoO2 up to the range of 1.25 Li+ the compound is formed which possesses maximum capacity about 343 mA·h/g, reveals cycling stability with but 100-percent colonic effectiveness, and may be perspective for use as anode material of lithium-ionic batteries. At intercalation of lithium into lithium-manganese spinels (over-discharge) visible phase transformations do not occur, and materials remain electrochemically active in the high-voltage area, i.e. single over-discharges of the cathode do not lead to lowering the material characteristics. It has been found the effect of rising the current specific capacity in the three-volt area for spinel doped by aluminum after single intercalation of lithium up to 1.5 V. It is perspective for developing new cathode materials of high specific capacity for operation in wide diapason of potentials - (2.4-5.0) V.5481
