A Lithium-transition-metal-phosphate compound of formula LiFeMPO) in the form of secondary particles made of agglomerates of spherical primary particles wherein the primary particles have a size in the range of 0.02-2 pm and the secondary particles a mean size in the range of 10-40 pm and a BET surface of 16-40 m/g, a process for its manufacture and the use thereof.

Lithium transition metal phosphate secondary agglomerates and process for its manufacture

A process for the preparation of carbon-coated lithium transition metal phosphate having the formula LiMMnPOand its use as cathode material in secondary lithium-ion batteries wherein the process includes few synthesis steps which can be conducted easily, therefore providing a low cost process and results in a complete reaction of the starting material compounds or the mixtures thereof. At least one starting material compound is dispersed or dissolved in an essentially aqueous medium and heated to a temperature between 50&#xb0; C. and 100&#xb0; C. prior to addition of the remaining starting material compounds.

Process for the preparation of carbon-coated lithium transition metal phosphate and its use

A substituted lithium-manganese metal phosphate of formulaLiFeMnMPOin which M is a bivalent metal from the group Sn, Pb, Zn, Ca, Sr, Ba, Co, Ti and Cd and wherein: x&#x3c;1, y&#x3c;0.3 and x+y&#x3c;1, a process for producing it as well as its use as cathode material in a secondary lithium-ion battery.

Substituted lithium-manganese metal phosphate

A carbon-containing lithium titanium oxide containing spherical particle aggregate with a diameter of 1-80 &#x3bc;m, consisting of lithium titanium oxide primary particles coated with carbon. Also, a method for the production of such a carbon-containing lithium titanium oxide as well as an electrode containing such a carbon-containing lithium titanium oxide as active material as well as a lithium-ion secondary battery containing an above-described electrode.
