Natural molybdenite has the advantages of low cost and high lithium storage capacity, which can be directly used as an anode material of lithium-ion batteries. In this paper, expanded molybdenite/carbon (EM/C) composites were constructed via expanding molybdenite and surface modification with dopamine. The worm-like structure of expanded molybdenite (EM) has a high specific surface area that is conducive to electrolyte infiltration and diffusion of lithium ions. The amorphous carbon layer effectively increases its electrical conductivity and provides a buffer space for volume enlargement during MoS2 cycle. The EM/C composites have a long cycle life and a high capacity, with a capacity of 1 213 mA·h/g at 100 mA/g after 200 cycles and a reversible capacity of 623 mA·h/g even at 1 A/g. The strategy of EM/C composite material constructed from molybdenite fine powder has a specific guiding significance to achieve the superior electrochemical performance of lithium-ion battery.

天然辉钼矿具有低成本、高储存锂的优势,可直接用作锂离子电池负极材料。首先对辉钼矿进行膨胀处理,然后利用多巴胺进行表面改性,构建了膨胀辉钼矿/碳(EM/C)复合材料。膨胀法制备的蠕虫状膨胀辉钼矿(EM)具有较高的比表面积,有利于电解质的渗透和锂离子的扩散。无定形碳层有效地提高了其电导率,并为MoS2循环过程中体积变大提供了缓冲空间。EM/C复合材料具有较长的循环寿命和高容量,在电流密度100 mA/g下,循环200圈容量仍可高达1 213 mA·h/g,即便在1 A/g的大电流密度下,仍有623 mA·h/g的可逆容量。以辉钼矿精粉为原料构建EM/C复合材料的策略,对实现锂离子电池优异的电化学性能具有一定指导意义。

天然辉钼矿具有低成本、高储存锂的优势,可直接用作锂离子电池负极材料。首先对辉钼矿进行膨胀处理,然后利用多巴胺进行表面改性,构建了膨胀辉钼矿/碳(EM/C)复合材料。膨胀法制备的蠕虫状膨胀辉钼矿(EM)具有较高的比表面积,有利于电解质的渗透和锂离子的扩散。无定形碳层有效地提高了其电导率,并为MoS2循环过程中体积变大提供了缓冲空间。EM/C复合材料具有较长的循环寿命和高容量,在电流密度100 mA/g下,循环200圈容量仍可高达1 213 mA·h/g,即便在1 A/g的大电流密度下,仍有623 mA·h/g的可逆容量。以辉钼矿精粉为原料构建EM/C复合材料的策略,对实现锂离子电池优异的电化学性能具有一定指导意义。

Natural molybdenite has the advantages of low cost and high lithium storage capacity, which can be directly used as an anode material of lithium-ion batteries. In this paper, expanded molybdenite/carbon (EM/C) composites were constructed via expanding molybdenite and surface modification with dopamine. The worm-like structure of expanded molybdenite (EM) has a high specific surface area that is conducive to electrolyte infiltration and diffusion of lithium ions. The amorphous carbon layer effectively increases its electrical conductivity and provides a buffer space for volume enlargement during MoS2 cycle. The EM/C composites have a long cycle life and a high capacity, with a capacity of 1 213 mA·h/g at 100 mA/g after 200 cycles and a reversible capacity of 623 mA·h/g even at 1 A/g. The strategy of EM/C composite material constructed from molybdenite fine powder has a specific guiding significance to achieve the superior electrochemical performance of lithium-ion battery.
