- A precursor cathode active material (pCAM) is a powder-like substance that is a critical component in the manufacture of lithium-ion batteries. It is a mixed-metal hydroxide of nickel, cobalt, and other chemical elements. The pCAM is synthesized through a process called precipitation, which involves mixing solutions of the metal salts and then adding a base to cause the metal hydroxides to precipitate out of solution. The pCAM is then filtered, washed, and dried. The pCAM is then used to produce the cathode active material (CAM), which is the heart of the lithium-ion battery. The CAM is made by heating the pCAM to a high temperature in a controlled atmosphere. This process causes the metal hydroxides to decompose and form a crystalline structure that is able to store and release lithium ions. The CAM is then mixed with other materials, such as a conductive binder and a porous separator, to form the cathode electrode. The cathode electrode is then assembled with the anode electrode and the electrolyte to form the lithium-ion battery. Here are some of the key properties of pCAM: High purity, Good morphology, High reactivity.
