This product is designed for lithium-ion battery research and development, specifically as a cathode electrode sheet based on NCM622 (LiNi₀.₆Co₀.₂Mn₀.₂O₂) single-crystal active material. It is engineered for consistent electrochemical testing, with recommended use of 622 deduction electrolyte or ternary electrolyte (KLD-1230C) to achieve reliable performance. The electrode sheet requires rolling at an appropriate compacting pressure and vacuum baking at 105°C for 4 hours prior to use. Proper storage in vacuum-sealed or glove-box conditions is critical, especially for high-nickel materials, to prevent increased internal resistance. Single-sided sheets may exhibit curling after rolling; fold marks from flattening and packaging should be noted. This product is commonly employed in coin-cell or pouch-cell assembly for evaluating NCM cathode performance under controlled test protocols, with a recommended sealing pressure of 1300 psi during constant-current charging.
