Elcora Advanced Materials Corporation mines, processes, refines graphite and targets high-end graphite**markets for Lithium-ion batteries. The company has identified a significant opportunity in expanding its**existing product range according to broader customer requests/ interest. They are looking to develop a**secondary product, a coated spheronized graphite from their existing product (spheronized graphite). This**opportunity will differentiate their product and increase the Elcora's customer base as customer's will be more**likely to purchase company's graphite powder having lower surface area and coating of thin film of amorphous**carbon. Thus, the company is looking for fluidized bed options to uniformly coat the graphite spheres of**diameters 25 micrometer.**Since Elcora doesn't have expertise on Chemical vapor deposition (CVD) by fluidization, the company seeks**the assistance of Prof. Basu who is an expert in fluidization technology and its principles, to develop a novel**method of CVD by fluidization.**This project would provide scientific assistance to Elcora Advanced Materials Corporation to develop an**fluidized bed reactor for coating amorphous carbon on graphite for Lithium ion battery application. Applicant**proposes to develop a fluidized bed reactor for coating carbon by CVD that will have more uniform coating**than fixed bed or stirring assisted fixed bed reactor. This project needs to research into a new area or**fluidization technology to develop a new options for fluidized bed of fine particles for coating at very high**temperature and then to build and test a proof of concept unit.**With this prototype reactor, Elcora will be able to evaluate the effectiveness of this new technology and**develop the prototype into mass production units, differentiating their product, reducing production costs and**improving quality.
