A process for preparing a structure both acting as a positive electrode and a current collector for a lithium-sulphur battery operating in a "catholyte" type configuration or containing a sulphur active material therein, said process comprising the following operations of: - depositing one or more liquid compositions comprising the components of this structure onto a removable substrate; - drying the composition(s) deposited; - separating the removable substrate from the structure thus obtained, which is the structure both acting as a positive electrode for a lithium-sulphur battery and a current collector, wherein: - when the structure is for being part of the composition of a lithium-sulphur accumulator operating in a "catholyte" type configuration, the depositing consists in depositing onto the removable substrate a single liquid composition comprising the components of said structure; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a single composition comprising the components of said structure, including, in this case, a sulphur active material; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a first composition comprising the components of said structure except for the sulphur active material and a second composition comprising the sulphur active material, wherein a drying can be interposed between both compositions deposited; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a composition comprising the components of said structure except for the sulphur active material, the sulphur active material being introduced into the structure after separating the removable substrate. - depositing one or more liquid compositions comprising the components of this structure onto a removable substrate; - drying the composition(s) deposited; - separating the removable substrate from the structure thus obtained, which is the structure both acting as a positive electrode for a lithium-sulphur battery and a current collector, - when the structure is for being part of the composition of a lithium-sulphur accumulator operating in a "catholyte" type configuration, the depositing consists in depositing onto the removable substrate a single liquid composition comprising the components of said structure; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a single composition comprising the components of said structure, including, in this case, a sulphur active material; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a first composition comprising the components of said structure except for the sulphur active material and a second composition comprising the sulphur active material, wherein a drying can be interposed between both compositions deposited; or - when the structure contains a sulphur active material therein, the depositing consists in depositing onto the removable substrate a composition comprising the components of said structure except for the sulphur active material, the sulphur active material being introduced into the structure after separating the removable substrate. <EOS>
