Estimating the term…
An engineered carbonaceous material (ECM) comprising a mixture of synthetic graphite and one or more other graphite, such as natural flake graphite, natural vein graphite, and/or amorphous graphite. The objects are also achieved by an ECM comprising a mixture of expanded graphite and one or more other graphite materials, such as natural flake graphite, natural vein graphite, amorphous graphite and/or synthetic graphite. The ECM is preferably mixed with 0.01 to 20.0 wt. % MnO2 to create a battery active material. The mixtures may be made by either co-blending or co-grinding the graphites together. An electrochemical cell incorporating the material is also contemplated.
An engineered carbonaceous material comprising synthetic graphite co-blended with one or more graphite materials selected from the group consisting of natural flake graphite, natural vein graphite, and amorphous graphite and further comprising 0.01 to 20.0 wt % of an electrode active material.
An engineered carbonaceous material comprising expanded graphite co-blended with one or more graphite materials selected from the group consisting of natural flake graphite, natural vein graphite, amorphous graphite, and synthetic graphite and further comprising 0.01 to 20.0 wt % of an electrode active material.
An engineered carbonaceous material comprising synthetic graphite co-ground with one or more graphite materials selected from the group consisting of natural flake graphite, natural vein graphite, and amorphous graphite and further comprising 0.01 to 20.0 wt % of an electrode active material.
An engineered carbonaceous material comprising expanded graphite co-ground with one or more graphite materials selected from the group consisting of natural flake graphite, natural vein graphite, amorphous graphite, and synthetic graphite and further comprising 0.01 to 20.0 wt % of an electrode active material.
An engineered carbonaceous material comprising 99.7 wt % expanded natural crystalline flake graphite sized to have a d50 of 25.0 microns and 0.3 wt % electrolytic manganese dioxide sized so that 99.8% is no greater than 45 microns.
