ELECTROACTIVE MATERIALS FOR METAL-ION BATTERIES

The invention relates to a particulate material and processes for the preparation thereof. The particulate material consists of a plurality of composite particles. The composite particles comprise a porous particle framework comprising micropores and/or mesopores. The total pore volume of micropores and mesopores as measured by gas adsorption is in the range from 0.4 to 2.2 cm/g. The composite particles comprise a plurality of electroactive material domains and a plurality of modifier material domains disposed within the internal pore volume of the porous particle framework. At least a portion of the modifier material domains are located between adjacent electroactive material domains.
