This product is a bare (uncoated) polycrystalline NCM523 lithium nickel cobalt manganese oxide cathode material, developed for experimental battery research and energy materials studies. Due to its strong moisture absorption, vacuum-sealed storage and strict humidity control are required throughout processing. For electrochemical testing, the recommended electrolyte is a dedicated NCM formulation (KLD-1230C), and electrodes should be baked at 85°C for 4 hours prior to use. This uncoated variant is well-suited for half-cell testing and rate capability evaluations, as illustrated by the charge/discharge performance data provided. Available in 20g, 50g, and 100g quantities, it offers a controlled baseline for investigating intrinsic cathode behavior without the influence of surface coatings.
