Process for modifying an electrode active material according to general formula LiTMO2, wherein TM contains a combination of Ni and at least one transition metal selected from Co and Mn, and, optionally, at least one metal selected from Al, Ba, and Mg and, optionally, one or more transition metals other than Ni, Co, and Mn, wherein at least 75 mole-% of TM is Ni, and x is in the range of from −0.05 to 0.2, said process comprising the steps of (a) treating said LiTMO2 with an aqueous medium with a pH value of at least 5 and up to 14, (b) removing said aqueous medium from treated LiTMO2 by way of a solid-liquid separation, wherein steps (a) and (b) are commenced with a maximum time difference of 3 minutes. In addition, the present invention is directed towards Ni-rich electrode active materials.

Method for processing Ni-rich electrode active materials

The present invention relates to a method for preparing a concentrated polysaccharide mass, in particular a method for preparing concentrated glucan or schizophyllan, in particular a method for redispersing glucan or schizophyllan for producing a ready-to-use mass.

Redispersion of schizophyllan

The presently claimed invention is directed to a method for the preparation of an aqueous solution comprising at least one beta-glucan comprising at least the steps of a) fermentation of at least one fungal strain in an a fermentation broth, b) addition of at least one acid to the fermentation broth to adjust the pH to a value in the range of &#x2265;2.0 to &#x2264;4.0 and c) filtration of the fermentation broth to obtain an aqueous solution comprising the at least one beta-glucan and at least one beta-glucan that is obtained by this method.

Method for the discontinuous thermal treatment of catalyst material

The invention relates to a process for preparing alkali metal alkoxides by reacting alkali metals with alcohols in the presence of a catalyst, preferably a transition metal salt and especially iron(III) chloride.

Method for producing alkali metal alcoholates

Orthoesters are prepared by reacting 1,1,1-trihaloalkanes with alkali metal alkoxides in the presence of the corresponding alcohol, a slurry of the alkali metal alkoxide in the corresponding alcohol being used.

Preparation of orthoesters

A crystalline solid which has a sufficiently low hygroscopicity for processing and use and essentially consists of glycine-N,N-diacetic acid derivatives is prepared by adjusting the water content of the starting material containing the glycine-N,N-diacetic acid derivatives to a value of from 10 to 30% by weight, based on the starting material, and subsequently bringing about crystallization.
