Comm with around 200 mAh g -1 (corresponds to ca. 1.2 Li + per MoS2), indicating additional charge storage for nanocrystalline MoS2 materials. While this effect has been observed before for nanostructured MoS2 and is attributed to surface redox reactions, it is remarkably also observed for MoS2 TU with a SSA even smaller than that of commercial MoS2 Comm, clearly demonstrating the significance of nano-crystallinity over accessible surface area for maximizing the reversible (de)lithiation capacity of MoS2 .
