CHEMICAL SOURCE OF CURRENT Russian patent published in 2011 - IPC H01M6/18 H01M10/36 

FIELD: electricity.

SUBSTANCE: according to the invention, the chemical current source comprises an anode of alkaline or alkali-earth metal, for instance, lithium (Li), a cathode of a mixture of several elements of electric negative subgroups of V-VI groups of the Periodical system of elements, or one of these elements, for instance, sulfur (S), tellurium (Te), a solid electrolyte arranged between them and made of a chemical compound with ionic conductivity, or a mixture of chemical compounds of anode and cathode substance, and also current collectors, the cathode additionally includes an electrolyte that contains a cation of anode substance, at the same time the amount of the electrolyte introduced into the cathode makes from 10% to 70% from the cathode volume, and the cathode is made of two zones: the first zone bordering with the solid electrolyte, containing a mixture of the cathode substance with electrolyte, and the second zone bordering with the first one, containing an electron conductor apart from the specified substances.

EFFECT: increased time of discharge and capacitance of chemical sources of current.
