Traditionally, cathode production involves intricate processes that can be both energy-consuming and environmentally damaging. For instance, using Nickel Manganese Cobalt (NMC) cathodes exemplifies a common production method that initiates at a chemical plant, where metals are combined with sulfuric acid to create metal sulfates. This method entails several steps, including mixing with water and carbonates, a separation stage that generates extensive wastewater, and additional drying, grinding, and classification phases.
