Method and system for gradient separation of nickel, cobalt and manganese elements in ternary battery based on multi-stage extraction

Abstract

The application provides a ternary battery nickel-cobalt-manganese element gradient separation method and system based on multi-stage extraction, relates to the field of adaptive control technology, and comprises the following steps: acquiring real-time monitoring data of a multi-stage extraction system; adopting a graph structure to construct a cascading relationship node sequence, setting an attention module to extract features and adaptively adjust node sampling weights; constructing a multi-stage collaborative control strategy based on ion concentration prediction values, dividing the extraction unit into different enrichment zones, and adopting a reinforcement learning algorithm to optimize control parameters; and realizing efficient separation of nickel, cobalt and manganese elements by adjusting the control parameters. The application improves the separation efficiency, reduces energy consumption, and reduces the amount of chemical reagents.
