Material, In Particular For Use In Electrochemical Cells Or Supercapacitors And A Method Of Making Such A Material

摘要

A material in particular for use in electrochemical cells or supercapacitors comprises a poorly conducting active material of relatively low conductivity having regular or irregular passages having average cross-sectional dimensions generally in the size range from 5μm to 200 nm and interconnected mesopores having average cross-sectional dimensions in the size range from 2 to 50 nm. The active material is covered with a network of an electronically conductive metal oxide of relatively high conductivity extending into said mesopores. Also claimed is a method of manufacturing such a material.
