摘要：With the unprecedented heat of lithium resources, it has been a hot topic to find an effective, low-energy-consumption, and eco-friendly method for extracting lithium from salt lakes. As an electrochemically active material, LiMn2O4(LMO) is widely used in electrochemical lithium extraction. In order to reduce the Mn dissolution loss and improve the cycle stability of LMO, we designed octahedral LMO with controllable particle size by adjusting the water/ethanol volume ratio of the precursor solution. Through the electrochemical performance test, it was found that with the increase in particle size, the cycle stability of LMO and the lithium ion transport performance also improved. The Mn dissolution loss per 30 cycles of LMO (B-LMO) was 0.187%, and the capacity was maintained at the initial 86.9%. The electrochemical lithium extraction system of B-LMO//Ag exhibits excellent lithium extraction performance. After 1 h of extraction, the lithium extraction capacity is 20.6 mg/g, and the energy consumption is 15.2 Wh/mol. ? 2023
