Polystyrene‐Templated Aerosol Synthesis of MoS 2 –Amorphous Carbon Composite with Open Macropores as Battery Electrode

MoS 2 –amorphous carbon (MoS 2 –AC) composite microspheres with macroporous structure were fabricated by one‐pot spray pyrolysis. Single‐ or few‐layered MoS 2 were uniformly dispersed and oriented in random directions in the amorphous carbon microsphere with macropores sizes between 50 and 90 nm. The macroporous microspheres having a high contact area with liquid electrolyte exhibited overall superior Li‐ and Na‐ion storage properties compared with those of the dense microspheres. After 250 charge/discharge cycles at a current density of 1.5 A g −1 , the discharge capacities of the MoS 2 –AC microspheres with dense and macroporous structures for Li‐ion storage were 694 and 896 mAh g −1 , respectively. In the case of Na‐ion storage, discharge capacities of 336 and 425 mAh g −1 were achieved for the dense and macroporous microspheres, respectively, after 100 cycles at 0.3 A g −1 .
