FIELD: electrical industry.
SUBSTANCE: group of inventions relates to the electrical industry, in particular to the production of secondary chemical current sources, and can be used in the manufacture of positive electrodes for lithium-sulphur batteries. Technical task is achieved by using polymers in the design when making the electrode, which can swell in the electrolyte, retain the required amount of electrolyte and form an ion-conducting phase (gel polymer electrolyte).
EFFECT: development of design and manufacturing method of laminated positive electrode for lithium-sulphur accumulators, containing amount of electrolyte required for complete electrochemical conversion of sulphur and a separator tightly coupled with the active layer of the electrode, preventing short-circuiting of the positive and negative electrodes.
