Graphite for Battery Materials

What is Graphite material? Graphite material is most commonly used to serve as the anode material for lithium-ion battery manufacturing due to its relatively low-cost and its energy density. Advanced graphite material has great thermoconductive properties and for the most part is readily available. 3 main types of graphite are used in the process; natural, synthetic, and spherical graphite. All have their advantages and disadvantages, but regardless they need to be sieved to fine sizes to work for the industry. Screening graphite for battery materials can be a tricky process due to the varying shape of graphite. Many of the powder requirements call for it to be below 44 microns and traditional screeners do not have the energy to sieve graphite at these sizes.

Elcan's Experience

Elcan Industries works closely with many graphite users and producers to help them sieve graphite powder into very fine and tight specs. The key is having energy on the screen in order to separate graphite at sizes as fine as 10 microns. The shape of the graphite effects the amount of energy needed to make the separation, but the hi-sifter system can handle all forms of the powder. For finer separations of graphite down to 1 micron, the Elbow Jet system is better suited. Both systems contain no organic materials or rotating parts and are available for testing and tolling at Elcan.
