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.

Elcora先进材料公司开采、加工、提炼石墨，并瞄准锂离子电池的高端石墨市场。该公司已经发现了根据更广泛的客户需求/兴趣扩展其**现有产品范围的重要机会。他们正在寻求开发一种**二次产品，一种由现有产品(球化石墨)制成的涂层球化石墨。这一**机会将使他们的产品与众不同，并增加Elcora的客户基础，因为客户将更有**可能购买公司的表面积较小的石墨粉和无定形**碳薄膜的涂层。因此，该公司正在寻找流态床方案，以均匀地覆盖**直径25微米的石墨球。**由于Elcora在流态化化学气相沉积(CVD)方面没有专业知识，该公司寻求**流态化技术及其原理专家巴苏教授的帮助，开发一种新颖的流态化CVD方法。**该项目将为Elcora先进材料公司开发**流态化反应器，用于在锂离子电池应用的石墨上涂覆无定形碳。申请人**提议开发一种用于CVD包覆碳的流态化反应器，它将比固定床或搅拌辅助固定床反应器**具有更均匀的涂层**。该项目需要研究新的领域或**流态化技术，以开发用于在很高**温度下进行涂层的细颗粒流态化的新选项，然后建造并测试概念验证单元。**有了这个原型反应器，Elcora将能够评估这项新技术的有效性，并**将原型开发成批量生产单元，使其产品差异化，降低生产成本，**提高质量。
