At THERSER UK, we specialize in the advanced calcination processes required for the production of Cathode Active Material (CAM) used in lithium-ion batteries, and Anode The cathode, or positive electrode, is a crucial component of these batteries, typically composed of lithium metal oxides.
While traditional lithium-ion batteries use lithium cobalt oxide for the cathode, recent advancements have introduced alternative material systems. Despite these innovations, lithium and oxygen remain integral to the structure, with cobalt often being replaced partially or entirely by metals such as nickel and manganese. These alternative compositions are referred to as lithium metal oxide cathodes.
The performance of lithium-ion batteries heavily depends on the microstructure, morphology, particle size, and purity of the cathode material. These parameters influence the electrochemical characteristics, including the energy density, which is critical for applications like electric vehicles.
Achieving the optimal microstructure for cathode materials involves meticulous selection of raw materials and a controlled production process. Lithium metal oxides are formed by thermally treating a mixture of individual metal oxides at high temperatures (800-1000 °C) under specific atmospheric conditions. This process begins with raw materials such as lithium hydroxides or carbonates.
Calcination, the initial step in the production of cathode materials, involves heating raw materials to release water (H2O) or carbon dioxide (CO2) at temperatures between 600-800 °C. This reaction produces the oxides necessary for the next stage, where these oxides form a mixed crystal through further thermal treatment.
