Abstract: FIELD: electrochemistry.  
     SUBSTANCE: invention relates to the field of chemical current sources, in particular to metal-bromine non-flowing batteries, namely, to methods for manufacturing its positive electrode. The essence of the invention consists in the fact that the positive electrode of a metal-bromine non-flowing battery is formed of at least one layer of flat carbon foil and at least one layer of a porous electrically conductive carbon active material, which provides adsorption of liquid bromine released during electrolysis and accumulates bromine in the pores of the active material. At the same time, the pores of the active material have different sizes and are characterized by the presence of macro-, meso- and micropores, and the layers of materials are directly in contact with each other. According to the invention, in the process of preparing the active porous material for the assembly of the electrode, the surfaces of the macro- and mesopores of the active material are blocked by modifying these surfaces with polymers or salts containing an organic ion by adsorbing them in the macro- and mesoporous structure of the carbon active material when the active material is aged in polymer solutions or in organic salts. At the same time, it is ensured that the modifying material does not penetrate into the micropores by selecting the ratio of the size of the micropores and the size of the chains of the modifying material. Moreover, in the active material of the electrode, before the process of modifying its surface, oxygen-containing functional groups are removed by pretreatment in a high-temperature hydrogen furnace at a temperature of 750-800°C.  
     EFFECT: increase in the efficiency of halogen adsorption due to the exclusion of macro- and mesopores from the manufacturing process.
