AI Technical Summary
Traditional lithium manganese oxide electrodes suffer from poor cycle stability and insufficient selectivity for lithium ions during lithium ore processing, especially in high-salt, multi-ion coexistence systems, making it difficult to efficiently extract lithium resources.
By calcining lithium manganese oxide and terbium salt, LiMn2-xTbXO4 active material is formed. Then, a voltage is applied in the delithiation three-electrode system to form a second active material with lithium vacancies, which suppresses the Jahn-Teller effect and manganese dissolution, and improves cycle stability and selectivity.
It significantly improves the cycling stability and lithium-ion selectivity of the electrode, enabling efficient extraction of lithium resources in complex systems, and is suitable for complex systems such as lithium slag leachate and salt lake brine.
