POSITIVE ELECTRODE AND PRIMARY LITHIUM CHEMICAL CURRENT SOURCE CONTAINING IT Russian patent published in 2022 - IPC H01M4/00 H01G11/08 H01M10/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, namely to the electrode material of a positive electrode, a positive electrode and a non-rechargeable (primary) lithium chemical current source. The invention is aimed at the creation of a positive electrode material for a primary lithium chemical current source with a specific capacity from 400 to 570 mAh per gram of electrode coating (when discharged with a nominal current density of 0.3 mA/cm²), providing a continuous discharge current of at least 2 A per gram of electrode coating or at least 30 mA per square centimeter of the electrode, which is provided by the fact that the cathode active material contains a carbon conductive additive, a polymer binder and a CF_x fluorinated carbon mixture, and also vanadium oxide V₂O₅, where fluorinated carbon is a CF_x compound, where 0.5≤x≤1.2, while the content of vanadium oxide V₂O₅ in the material is from 40% to 80%, fluorinated carbon CF_x from 10% to 50%, while the ratio of the mass content of vanadium oxide (V₂O₅) to fluorinated carbon (CF_x) is from 0.8 to 8.

EFFECT: creation of a positive electrode material for a primary lithium chemical current source.
