Experimental Design of Lithium Nickel Manganese Oxide (LNMO) with aqueous binders from lab scale to pilot line

The growing demand for high-performance lithium-ion batteries (LIBs) has led to exploring novel active materials and manufacturing techniques. Lithium Nickel Manganese Oxide (LiNi0,5Mn1,5O2, LNMO) has emerged as a promising cathode material due to its high energy density and thermal stability. Transitioning from lab-scale to pilot line and large-scale production presents notable challenges, particularly ensuring consistent performance and reproducibility.
This study introduces an experimental design to utilize aqueous binders, such as carboxymethyl cellulose (CMC) and sodium alginate (SA), to produce sustainable and green LNMO electrodes while addressing the transition from laboratory experiments to pilot lines. Key aspects such as binder selection, electrode formulation, processing parameters, and performance evaluation are systematically investigated. The research examines the impact of the electrode composition and effectivity of aqueous binders on the electrochemical performance of LNMO electrodes, focusing on optimizing performance, stability, and scalability.
These experimental procedures also employ essential characterization techniques, such as viscosity measurements, pH analyses, electrochemical tests, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM), microscopic images, contact angle evaluations, and resistance tests. These analyses contributed significantly to comprehensively understanding the materials and their performance.
The results of this study facilitate the development of sustainable manufacturing processes for aqueous-based LIBs with LNMO, paving the way for their commercialization and widespread adoption in various sectors, including industry and electromobility.
