Graphite for Battery Materials

What is Graphite material? Graphite is the most commonly used to serve as the anode material in lithium-ion battery manufacturing due to its relatively low-cost and its energy density. Graphite has great conductive 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 at fine sizes to work for the industry. Sieving 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 screen graphite at these sizes.

Contract Manufacturing Experience

Elcan Industries works closely with many graphite users and producers to help them sieve graphite powder into very fine and tight specifications. 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. 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 since there are no screen openings that small. Both technologies contain no rotating parts/high wear items and are available for testing or tolling at Elcan. If you would like to schedule a trial to run Graphite powder at our toll processing facility to see how sieving Graphite on the Hi-Sifter can improve your process, give us a call at (914) 381-7500!
