ACCUMULATOR BATTERY WITH IMPROVED MOBILITY OF LITHIUM IONS AND IMPROVED CAPACITANCE OF CELLS Russian patent published in 2009 - IPC H01M4/58 H01M10/36 

Abstract RU 2361326 C2

FIELD: physics.

SUBSTANCE: invention relates to an accumulator (secondary) battery with improved mobility of lithium ions and increased capacitance of cells. According to the invention, active cathode material for the lithium accumulator battery contains two or more active materials with different redox levels, so as to exhibit the best discharge characteristics in the discharge range with large current after serial operation of active cathode material in the discharge process. This active cathode material consists of active materials of two types. The two types of active material have different average particle size, so as to increase density of the electrode.

EFFECT: improved discharge characteristics, increased capacitance of cells due to increased electrode density and specific capacitance of the electrode, increased power of the battery.
