Abstract

The high-value utilization of manganese ore tailings is of great significance for saving mineral resources and achieving environmental protection. Herein, an olivine LiFe_0.5Mn_0.5PO₄/rGO composite is synthesized by a simple precipitation method and subsequent high-temperature calcination process using the manganese ore tailings as raw material. The prepared LiFe_0.5Mn_0.5PO₄/rGO composite exhibits superior cycling stability (with 113.5 mAh·g⁻¹ after 300 cycles at 1.0C (1.0C = 170 mA·g⁻¹)) and superior rate performance (with 65.6 mAh·g⁻¹ at 10.0C). Ex-situ XRD and electrochemical impedance spectroscopy (EIS) analyses evidence that the LiFe_0.5Mn_0.5PO₄/rGO material has excellent structural stability and electrochemical reversibility during charge and discharge processes. Furthermore, the LiFe_0.5Mn_0.5PO₄/rGO//graphite full Li-ion battery also exhibits excellent cycling stability indicating its potential commercialization value.

利用锰矿尾渣制备的橄榄石型 LiFe0.5Mn0.5PO4/rGO 复合正极材料具有优异的锂存储性能

锰矿尾矿的高值化利用对于节约矿产资源、实现环境保护具有重要意义。本文以锰矿尾渣为原料，采用简单的沉淀法和高温煅烧工艺合成了橄榄石锂铁0.5Mn0.5PO4/rGO复合材料。所制备的 LiFe0.5Mn0.5PO4/rGO 复合材料表现出优异的循环稳定性（在 1.0C 下循环 300 次后达到 113.5 mAh-g-1（1.0C = 170 mA-g-1））和卓越的速率性能（在 10.0C 下达到 65.6 mAh-g-1）。原位 XRD 和电化学阻抗谱（EIS）分析表明，LiFe0.5Mn0.5PO4/rGO 材料在充放电过程中具有出色的结构稳定性和电化学可逆性。此外，LiFe0.5Mn0.5PO4/rGO/石墨全锂离子电池还表现出优异的循环稳定性，显示了其潜在的商业化价值。
