(EN) PRIMARY CHEMICAL CURRENT SOURCE BASED ON GRAPHENE
Abrégé
(EN)

The invention relates to the field of electrical engineering. The primary chemical current source is a new class of non-rechargeable, energy-saturated chemical current sources based on graphene in the metal-oxidized carbon electrochemical system, in which a nanostructured material based on graphene-like materials is used as a current-forming component of the cathode, which has an increased discharge capacity due to the presence of various oxygen-containing functions, capable of forming irreversible compounds with ions of the active material of the anode (for example, lithium, sodium, magnesium, calcium, potassium) during the current-forming process (discharge). The technical result is an increase in the energy performance of the primary chemical current source.
