摘要	Spinel LiMn2O4 (LMO) is commonly used for electrochemically extracting lithium ions from brine. However, its cycle stability is significantly reduced due to Mn2+ dissolution. Here, we report high-performance LMO particles decorated by Li1.5Al0.5Ge1.5(PO4)(3) (LAGP) as an electrode for electrochemical lithium extraction. Compared with bare sample, the modified electrode presents higher Li-ion selectivity because LAGP is a single Li-ion conductor, and as a result of avoiding the cointercalation of other ions in brine, the sample exhibits a higher Li-ion extraction capacity of 2.44 mmolg(-1). The cycling stability is also improved in LMO with LAGP coating by alleviating the loss of manganese, indicating a reduced Mn loss of 0.20% after 100 cycles compared to the LAGP free counterpart of 0.47%. Our work demonstrates an effective method for lithium purification from brine, and the detailed mechanism is also studied systematically.
