  • Method for preparing nickel-rich hydroxide precursor material and method for preparing nickel-rich oxide cathode material
    Patent number: 12709551
    Abstract: The present disclosure provides the methods for preparing nickel-rich hydroxide precursor material and nickel-rich oxide cathode material having a homogeneous structure with an element concentration-gradient distribution by utilizing a continuous Taylor-flow reactor, comprising: (1) preparing an aqueous solution A with metal ion raw materials dissolved therein, an aqueous solution B with a manganese source dissolved therein, an aqueous solution C with a precipitant dissolved therein, and an aqueous solution D with a chelating agent dissolved therein; feeding the aqueous solution A, the aqueous solution C and the aqueous solution D into the continuous Taylor-flow reactor to perform a first co-precipitation reaction; (2) feeding the aqueous solution B into the continuous Taylor-flow reactor to perform a second co-precipitation reaction; (3) washing the precipitate obtained from the second co-precipitation reaction and putting the precipitate into an oven to dry the precipitate to fabricate the nickel-rich hydro
