Embodiment Construction

[0071] Turning first to Figures 17A and 17B, the preferred non-graphitic carbon materials of the present invention will first be described. As shown in Figure 17A, it is indicated in the upper left of the figure how the non-graphitic carbon structure changes as it undergoes heat treatment (pyrolysis) at different temperatures. It can be seen from this figure that within the temperature range of 600°C to 1000°C involved in the present invention, that is, 873 to 1273°F, the structure includes a plurality of small graphite stacks 2 in random orientations. The stack itself comprises sheets of carbon atoms 4 arranged generally in a hexagonal arrangement. The sheet 4 shown as a rectangle in FIG. 17B is called graphene. There is no positional correlation of the carbon atoms within each graphene with the position of the carbon atoms in the graphene below or above.

[0072] As the heat treatment temperature increases, the non-graphitic carbon gradually becomes more ordered, transform...

Abstract

This disclosure relates to a porous electrically conductive carbon material having interconnected pores in first and second size ranges from 10[mu]m to 100nm and from less than 100nm to 3nm and a graphene structure and to diverse uses of the material such as an electrode in a lithium-ion battery and a catalyst support, e.g. for the oxidation of methanol in a fuel cell. The carbon material has been heat treated to effect conversion to non-graphitic carbon with the required degree of order at a temperature in the range from 600 DEG C to 1000 DEG C. A lithium-ion battery and an electrode for a lithium-ion battery are also claimed.

Description

technical field [0001] The invention relates to a porous conductive carbon material and its application, for example, in lithium ion battery or fuel battery. [0002] More specifically, the present invention relates to a porous carbon material particularly suitable for use as an electrode material in lithium-ion batteries, especially for electrodes known in the field of lithium-ion batteries as anodes; and for use in Fuel cells, especially direct methanol fuel cells; and as a general carrier medium, for example in chemical, electrochemical, biological or physical devices such as detectors, reactors or supercapacitors. Background technique [0003] Porous carbon materials are a well known class of materials. They are widely used mainly in the form of granular powders often commonly referred to as "activated carbon", e.g. as adsorbents for washing and purifying water media, filters and gas masks, air conditioning units, etc., and as catalyst supports Or as an electrode mater...
