In pursuit of high-performance cathode materials for lithium-ion batteries with high energy and power densities, porous LiFe0.4 Mn0.6 PO4 /CNF free-standing electrodes have been successfully prepared through a facile ionic liquid (IL) assisted electrospinning method. Owing to the hierarchical porosity and N-doped carbon layer derived from the ionic liquid, the resulting electrodes exhibited superior electrochemical performances with an improvement of conductivity and pseudocapacitive contribution, delivering a discharge capability of 162.7, 133.5, 114.5, and 102.6 mAh g-1 at the current rates of 0.1, 1, 5, and 10 C, respectively. It is highly expected that this facile IL-assisted electrospinning method will lead to further developments for other phosphate-based free-standing electrodes, which offers a new route in designing polyanionic cathodes for high-performance Li-ion batteries.

离子液体辅助静电纺丝多孔LiFe0.4 Mn0.6 PO4 / CNFs，具有用于高性能锂离子电池的伪电容性的自支撑阴极。

为了追求具有高能量和功率密度的用于锂离子电池的高性能阴极材料，已经通过一种简便的离子液体（IL）辅助电纺丝方法成功制备了多孔LiFe0.4 Mn0.6 PO4 / CNF自立式电极。由于离子液体具有分层的孔隙率和N掺杂的碳层，所得电极显示出优异的电化学性能，并改善了电导率和拟电容性，放电容量为162.7、133.5、114.5和102.6 mAh g-1电流速率分别为0.1、1、5和10C。高度期望这种简便的IL辅助电纺丝方法将导致其他基于磷酸盐的自立式电极的进一步发展，
