Project goal:The goal of the research project is to develop an efficient and cost-effective technology for two-stage solid-phase production of multi-element doped LiFePO4 cathode materials with improved electrochemical properties for use in LIB.
Project facilitators: PI – Nurzhan Umirov, Leading researcher Batukhan Tatykayev, Leading Researcher Natalya Khan, Senior Researcher Abylay Abilkhan, Junior Researcher Kamila Akhmetova, Junior Researcher Sultan Abilkairov, Junior Researcher Aruzhan Baitokova, Research Assistan
Realisation period: 2023-2025
Expected results: A new solid-phase technology will be developed for an efficient and cost-effective way to obtain multi-element doped LiFePO4 cathode materials with improved electrochemical properties for use in LIB.
Methodology: The project focuses on the development of nanostructured LiFePO₄/C cathode materials and their doped analogues for lithium-ion batteries using solid-state synthesis involving mechanical activation and thermal treatment. The use of mechanically activated solid-state synthesis enables control over particle size and uniformity, prevents aggregation, and improves carbon coating distribution. A range of doped compounds containing Mn, Co, V, Ni, and others will also be investigated to enhance electrochemical performance. Physicochemical properties will be studied using XRD, SEM, TEM, and TGA-DSC-MS, while electrochemical characteristics will be evaluated by cyclic voltammetry and galvanostatic testing in half-cells.
