A 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 conductiv- ity having regular or irregular passages having average cross-sectional dimensions generally in the size range from 5µm to 200nm and interconnected mesopores having average cross-sectional dimensions in the size range from 2 to 50nm. 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.
