Comparative Analysis of Synthesis Routes and Aluminum Doping Effects on Nickel-Manganese-Cobalt Type Cathode Material

Year: 2025

Type: article

Abstract: This study presents a comprehensive analysis of the synthesis techniques and the effects of aluminum doping on nickel-manganese-cobalt (NMC) 811 cathode materials. Our research focuses on the comparison of two different synthesis methods. Hydroxide co-precipitation is followed by solid-state calcination for polycrystalline (PC) cathodes and molten salt calcination for single-crystalline (SC) cathodes. In addition, the study systematically integrates aluminum dopants at different stages of these processes. This study aims to examine how various doping methods affect the structural characteristics, morphological features, and electrochemical performance of NMC cathodes.This investigation employs a thorough characterization approach, utilizing techniques such as X-ray diffraction (XRD), various microscopy methods, and galvanostatic cycling tests, our results illustrate the complexity of the synthesis parameters that influence the capacity retention and performance of the samples produced.
