LITHIUM BATTERY AND METHOD FOR ITS MANUFACTURING Russian patent published in 2014 - IPC H01M2/16 H01M10/52 H01M4/02 H01M4/485 H01M4/505 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering. The invention suggests the lithium battery that includes at least two volume electrodes divided by a separator and placed together with electrolyte containing anhydrous lithium salt in an organic polar solvent in the battery casing, each electrode has the minimum thickness of 0.5 mm and at least one of these electrodes contains a homogeneous pressed solution of an electroconductive component and active material that can absorb or set free lithium in the presence of electrolyte, at that porosity of the pressed electrodes is within the range of 25% - 90%, the active material has a hollow sphere structure with the maximum length of the wall of 10 micrometers or an aggregate or agglomerate structure with the maximum size of 30 micrometers, whereat the separator contains a high-porous electric insulating ceramic material with open pores and porosity from 30% up to 95%.

EFFECT: increasing capacity of small-size accumulator batteries.
