The invention relates to a method for producing a master batch comprising between 0.01 and 50 wt. % of carbonaceous nanofillers and at least one sulphurated material such as elemental sulphur by melt compounding, and to the master batch thus produced and the different uses thereof. The invention also relates to a solid composition comprising carbonaceous nanofillers dispersed in a sulphurated material.

The present document describes a method of producing sulfur particles by injecting an unbroken stream of molten sulfur under a pulsation free pressure, from a distance, into tempered water moving at a velocity, to produce a physical reaction of said molten sulfur with said tempered water to produce sulfur particles. Also described are sulfur particles produced by the process and methods of using the same for fertilizing soil.

The invention relates to a new generation of alkali-ion-sulphur batteries in which specific sulphur allotropes, particularly the Psi allotrope of sulphur, are used as the active material of the cathode. Alkali metals or alkaline-earth metals are used as anodes. A preferred production method describes the production of the Psi-sulphur fibres by a special form of electrospinning. Another preferred production method describes the addition of the cation source in liquid form during the production of battery stacks. Finally, the invention relates to specific preferred novel forms of embodiment of alkali-ion-sulphur batteries, which are characterised by significant advantages in terms of capacity and service life.

A process for preparing sulfuric acid may involve melting elemental sulfur in a melting stage to give molten sulfur. Sulfuric acid is subsequently produced from the molten sulfur. Further, sulfur-containing offgases formed in the melting stage may be subjected to oxidation in a supplementary oxidation stage in which sulfur-containing components of the offgases are oxidized to sulfur dioxide. The process may further involve processing the sulfur dioxide to give at least one reaction product. The melting stage may be operated without emissions by processing all of the offgases from the melting stage. An apparatus may be employed for carrying out such a process.

Provided are modified sulfur and a production method thereof, the modified sulfur including sulfur and a modifier, wherein the modifier is an unsaturated fatty acid-based modifier.

This invention relates to a lithium-sulfur battery and a method of manufacturing the same, and more particularly, to a molten salt-based lithium-sulfur battery and a method of manufacturing the same, in which a metal foam including lithium or a lithium alloy, as an anode active material, and sulfur or metal sulfide, as a cathode active material, is used as a support and a current collector, and a solid-state electrolyte is used to thus improve energy density and power output characteristics.
