High Purity COPPER(II) SULFIDE CAS#1317-40-4
This ultra-fine high-purity copper sulfide powder is synthesized via wet chemical precipitation craft under low-temperature sealed reaction environment, effectively controlling free elemental copper and heavy metal impurity content to meet strict raw material standard of new energy battery industry. The refined particle distribution improves electrochemical activity of finished electrode material, avoiding unstable capacity attenuation caused by excess impurity during battery charge and discharge cycle. Its black fine powder form features outstanding dispersion performance when blended with conductive agent and binder in electrode slurry preparation.
