A Silicon Monoxide Lithium-Ion Battery Anode with Ultrahigh Areal Capacity

[摘要] tsThe large-sheet holey graphene framework/SiO (LHGF/SiO) composite displays notably high recoverable strain, suggesting considerably improved mechanical flexibility and robustnessThe LHGF/SiO anode with a mass loading of 44 mg cm−2 delivers a high areal capacity of 35.4 mAh cm−2 at current density of 8.8 mA cm−2 and retains a capacity of 10.6 mAh cm−2 at 17.6 mA cm−2The LHGF/SiO anode with an ultra-high mass loading of 94 mg cm−2 delivers an extraordinary areal capacity up to 140.8 mAh cm−2, about 1–2 order of magnitude higher than those in typical commercial devices
