Nickel Manganese Cobalt (NMC) cathodes have been a popular choice for batteries due to their ability to carry charge effectively. One variant, NMC-811 is ideal as it is high in Ni content and is also stabilized by Mn and Co. In order for it to function properly, the particles should be evenly rounded out and less than 10 μm in diameter. There is no consensus as to how it should be synthesized, but this project looked into using liquid solutions to synthesize the product, finding a temperature to burn off excess contaminants, and collect the product via spray drying. Analysis of the data found that the product found a suitable temperature that would be suitable for burning off the contaminants and Scanning Electron Microscope (SEM) images found that some of the samples produced had the right size particles. However, X-Ray Diffraction (XRD) phase analysis found that the products were unevenly structured.
