Abstract
Official abstract text for this publication.
The invention relates to a novel lithium-sulphur type electrochemical battery A. According to the invention, the positive electrode (1) is made solely from a porous electronic conductor substrate forming a current collector and the electrolyte contains lithium polysulphides (Li 2 Sn) as sources of lithium and sulphur ions, said lithium polysulphides being formed ex-situ and not in the battery. The invention also relates to a method for the production of said device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lithium-sulphur electrochemical battery, comprising: a positive electrode, a negative electrode and, a separator inserted between the positive electrode and the negative electrode and impregnated with an electrolyte in liquid or polymer gel form, wherein the positive electrode is made solely from a porous electronic conductor substrate forming a current collector, the electrolyte comprises a lithium polysulphide Li 2 S n as a source of lit…
