The present invention relates to a solid composite for use in the cathode of a lithium-sulphur electric current producing cell wherein the solid composite comprises 1 to 75 wt.-% of expanded graphite, 25 to 99 wt.-% of sulphur, 0 to 50 wt.-% of one or more further conductive agents other than expanded graphite, and 0 to 50 wt.-% one or more binder, based on the total amount of the solid composite, a lithium-sulphur electric current producing cell comprising (i) a cathode comprising the solid composite, (ii) an anode and (iii) an electrolyte interposed between said cathode and said anode, and a process for preparing the solid composite comprising the steps (I) preparing a slurry comprising sulphur, expanded graphite, and optionally further components in a liquid medium by dispersing the sulphur, the expanded graphite, and optionally the further components in the liquid medium; (II) casting the slurry provided in step (I) on a substrate or placing the slurry provided in step (I) into a mold; and (III) removing some or all of the liquid medium from the slurry cast in step (II) to form a solid composite.

Use of expanded graphite in lithium/sulphur batteries

The present invention relates to a process for producing electrode materials, which comprises the following steps:

Process for producing electrode materials

A process for producing electrode materials, which comprises treating a mixed oxide which comprises lithium and at least one transition metal as cations with at least one oxygen-containing organic compound of sulfur or phosphorus or a corresponding alkali metal or ammonium salt of an oxygen-containing organic compound of sulfur or phosphorus, or a fully alkylated derivative of an oxygen-containing compound of sulfur or phosphorus.

A process for preparing modified mixed transition metal oxides, which comprises treating a precursor of a mixed oxide which comprises lithium and at least two transition metals as cations with at least one substance which is selected from compounds of phosphorus, silicon, titanium, boron or aluminum having at least one phenoxy or alkoxy group or at least one halogen.

Process for preparing modified mixed transition metal oxides

The present invention relates to a mixture comprising at least one plastic K and from 0.1 to 50% by weight, based on the entire mixture, of at least one compound A selected from the group consisting of borophosphates, borate phosphates, metalloborophosphates, and mixtures thereof, to a process for the production of said mixture, and to the use of said mixture as flame retardant.

Borophosphate, borate phosphate, and metal borophosphate as novel flame proofing additives for plastics
