A method for the production of lithium oxide and the use of such lithium oxide is described herein. The method includes reacting lithium carbonate with elemental carbon or a carbon source forming elemental carbon under certain reaction conditions. The reaction may be carried out in containers whose product-contacting surfaces are corrosion resistant to the reactants and products. The lithium oxide obtained according to the method described herein can used for the production of pure lithium hydroxide solutions or for the production of glasses glass ceramics or crystalline ceramics, for example, lithium ion conductive ceramics.

Method for producing lithium oxide

The disclosed subject matter relates to a method for obtaining cesium from aqueous solutions.

Method for obtaining cesium from aqueous starting solutions

A solvent-free mixture of a crude lithium borate salt and lithium hydride, wherein the lithium hydride is at least 0.001 wt. % and at most 10 wt. %, relative to the weight of crude lithium borate salt, wherein the mixture has a water content of at most 100 &#x3bc;mol/g and an acid content of at most 10 &#x3bc;mol H/g of crude lithium borate salt, method for producing the same, and use thereof for battery electrolytes.

Method for producing low-acid lithium borate salts and mixtures of low-acid lithium borate salts and lithium hydride

A crystalline, completely soluble lithium bis(oxalato)borate (LiBOB), to a method for producing the same and to the use of the lithium bis(oxalato)borate.

Crystalline, completely soluble lithium bis(oxalato)borate (LiBOB)

The invention relates to conducting salts which contain lithium bis(oxalato)borate (LiBOB) and mixed lithium borate salts of the type of formula (I), wherein the portion of compound (I) in the conducting salt is 0.01 to 20 mole-% and X in formula (I) is a bridge linked with the boron via two oxygen atoms, selected from formula (II), wherein Yand Ytogether=O, m=1, n=0 and Yand Yindependently represent H or an alkyl group with 1 to 5 C atoms, or Y, Y, Y, Yindependently represent OR (with R=alkyl group with to 5 C atoms), or H or an alkyl group with 1 to 5 C atoms, and wherein m=0 or 1, n=0 or 1, or Yand Yare members of a 5- or 6-membered aromatic or heteroaromatic ring (with N, O or S as the hetero element) which can be optionally substituted with alkyl, alkoxy, carboxy or nitrile, and if so, Yand Yare not applicable and n&#x3e;0, m=0 or 1. The invention also relates to a method for producing the inventive conducting salts. 

Conducting salts for galvanic cells, the production thereof and their use

A crystalline, completely soluble lithium bis(oxalato)horate (LiBOB), to a method for producing the same and to the use of the lithium bis(oxalato)borate.

The invention relates to an activated alkaline earth metal, to a method for its production and the use of the activated alkaline earth metal for the preparation of Grignard compounds and organoalkaline earth metal compounds.

Activated alkaline earth metal, in particular magnesium, for the preparation of organoalkaline earth metal compounds
