    Abstract: 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.

    Abstract: A process to prepare a solid cement composition; includes adding a meltable compound to an aqueous slurry of cement and; mixing until a homogeneous dispersion is obtained. The dispersion is placed in a mould, where the dispersion is set by hydration. Part of the meltable compound is melted at a temperature range of which the maximum is above the melting point of the meltable compound and a minimum below the melting point of the meltable compound. A material, either still as a dispersion or an already setting cement is exposed to heat development or a temperature gradient such that the temperature is at least above the congealing point of the meltable compound to obtain a solid cement composition.
