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.

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.

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.
