The present invention provides a process for preparing sulfur-containing branched organosilane polymers comprising: reacting sulfur with a vinyl silane compound in a solvent and in the presence of a catalytic amount of an accelerator at an elevated temperature of at least 40° C. The process, and the organosilane polymers obtained by using the process, are very suitable for application in battery technologies.

Process for preparing sulfur containing organosilane polymers

The present invention relates to an electric energy storage device, in particular a battery, at least comprising: —an anode comprising a divalent metal selected from magnesium, calcium, beryllium and zinc or a combination thereof or an alloy comprising at least one of these metals; —a cathode comprising elemental sulphur, or a sulphur-containing organosilane compound, or a mixture of sulphur-containing organosilane compounds, or a mixture of sulphur and sulphur-containing organosilane compounds grafted on the surface of the cathode; and—an electrolyte placed between the anode and the cathode; wherein the cathode comprises a current collector surface that has been at least partly modified by grafting the sulphur-containing organosilane compound or a mixture of sulphur-containing organosilane compounds thereon.
