The present invention relates to an electrode material comprising at least one sulfur-limonene sulfide component or a composite of the sulfur-limonene sulfide component with a first conductive component; electrodes, in particular cathodes, containing the electrode material; half-cells, cells, and batteries containing the electrodes; and processes for obtaining the electrode material, the electrode, the half-cell, the cell, and the battery comprising electrode material and/or electrodes of the present invention.

Electrode and electrode material comprising sulfur-limonene polysulfide for lithium-sulfur batteries

The present invention relates to a method of manufacturing an amorphous electrode material comprising the steps of:

Method of manufacture of an electrode material and an electrode material

An electrode material for a lithium-ion battery comprises a porous agglomeration of particles, the particles being formed from nanopowder of a transition metal oxide and comprising cores of stoichiometric transition metal oxide surrounded by under stoichiometric oxide of the transition metal. Also described and claimed are the use of a corresponding material in a lithium ion battery and a method of making such an electrode.

Electrode material for a lithium-ion battery and a method of manufacturing the same

A method of producing an alkaline single ion conductor with high conductivity includes: a) providing a hydrocarbon oligomer or polymer having immobilized acidic substituent groups selected from the group consisting of a sulfonic acid group, sulfamide group, a phosphonic acid group, or a carboxy group, in its alkaline ion form wherein at least a part of the acidic protons of the substituent groups have been exchanged against alkali cations, and b) solvating the hydrocarbon oligomer or polymer of step a) in an aprotic polar solvent for a sufficient time to effect a solvent uptake of at least 5% by weight and to obtain a solvated product, wherein the molar ratio of solvent/alkaline cation is 1:1 to 10,000:1, and which solvated product has a conductivity of at least 10S/cm at room temperature (24&#xb0; C.).

A copolymer containing, in addition to recurring elements of a sulfonated poly(arylene) containing exclusively recurring structural element(s) of the general formulas &#x2014;[&#x2014;Ar(SOM)-X&#x2014;]&#x2014; and &#x2014;[&#x2014;Ar(SOM)-Y&#x2014;]&#x2014;, wherein X and Y, which are identical or different from each other, each represent an electron-acceptor group, Arand Ar, which are either identical or different from each other, represent an aromatic or heteroaromatic ring system with 5-18 ring atoms; wherein the aromatic or heteroaromatic ring system, in addition to the SOM and the substituents X and Y, optionally comprises additional substituents which are not electron-donor groups; M represents monovalent cation and n is an integral number between 1 and 4; and wherein X, Y, Ar, Ar, M and n can be identical or different in various structural elements, independently of each other, one or several additional elements of at least one additional monomer or macromonomer.

Sulfonated poly(arylenes), polymer compounds and methods of producing the same

Hydrolytically and thermo-oxidatively stable sulfonated polyarylenes include the structural element &#x2014;X&#x2014;Ar(SOM)-Y&#x2014;. The aromatic ring carrying the sulfonic acid group is substituted exclusively by electron-acceptor bridge groups X and Y and, if applicable, by other non-electron-donor substituents. Their synthesis and application are also included.

Sulfonated poly(arylenes) as hydrolytically and thermo-oxidatively stable polymers

An extremely high-performance polyaniline electrode was prepared by potentiostatic deposition of aniline on hierarchically porous carbon monolith (HPCM), which was carbonized from mesophase pitch. A capacitance value of 2200 F gof polyaniline was obtained at a power density of 0.47 kW kgand an energy density of 300 Wh kg. This active material deposited on HPCM also has an advantageous high stability. These superior advantages can be attributed to the backbone role of HPCM. This method also has the advantages of not introducing any binder, thus contributing to the increase of ionic conductivity and power density. High specific capacitance, high power and energy density, high stability, and low cost of active material make it very promising for supercapacitors.

A non-aqueous electrolyte is disclosed. Exemplary embodiments include at least one ionically conducting salt, especially a lithium salt, a non-aqueous, anhydrous solvent for the ionically conductive salt, the solvent being selected to achieve a degree of dissociation of the ionically conductive salt in the non-aqueous solvent, at least one oxide in a particulate form, the oxide being selected such that it is not soluble in the solvent and such that it is water-free. The electrolyte can be used in a primary or secondary lithium battery, in a supercapacitor, in an electro-chromic display or in a solar cell.
