Industrial Graphite and Carbon

American Energy Technologies Company is excited to advertise our first product line of graphite and carbon for high tech industrial applications.

Carbon products find uses in a great variety of industries, ranging from the manufacture of ductile iron to metal smelting, break pads, oil drilling, lubrication, composite manufacturing, batteries, and many others. Carbon is the material of choice in thousands of applications due to its comparatively low weight in comparison to other alternatives (the specific gravity of graphite is 2,250 kg/m3), near complete chemical inertness in the temperature range (from infinitely low to approximately 450°C in air and over 3,000°C in inert gas), and comparatively low cost. Engineered grades of graphite feature excellent properties in regards to lubrication, electrical conductivity, spring-back characteristic, and chemical absorption.

American Energy Technologies Company is excited to feature its first product line of industrial graphite. It caters to the industries of advanced lithium-ion batteries, high performance thread compounds, and thermally and electrically conductive paints & coatings.

The product of the month is our spheroidal, surface treated artificial graphite grade LM1226, whose appearance is shown by HR SEMs.

The primary intended application of this grade is negative electrode active material for advanced lithium-ion batteries (LIB).

The LIB application calls for low specific surface area (in the case of LM1226 it is typically less than 0.9 m2/g); maximum packing density (the tap density of featured grade is above 1 m2/g); ability to be coated onto copper foil electrodes with excellent adhesion (presented by SEM); a near-theoretical reversible capacity (near 350 Ah/kg); and low irreversible capacity loss (in the case of LM1226 it is less than a low 1% in the presence of SEI-enhancers in electrolyte). Results of galvanostatic cycling reveal an excellent rate capability of this grade, which is also pronounced at the low temperatures.

AETC’s new line of spheroidal graphite is well positioned to deliver a viable and affordable alternative to the natural carbon coated graphites on the lithium-ion battery market, since the latter tend to suffer from poor rate capability and virtual inability to reduce their mean particle size below 12 microns due to technological limitations.

Besides applications in lithium-ion batteries, grades within this product line are designed to benefit the market of high performance thread compound industry by delivering ultra high purity, low PAH formulae that disperse with premium uniformity and increased weight loading of solids in the carrier compounds, thus aiding in assembly of parts, lubrication, and corrosion protection over time.
