Exploring rational synthesis procedures and optimizing electrode materials to promote the application of compressible lithium-ion batteries in intelligent wearable electronics is still a difficult challenge. Herein, compressible few-layered MoS2 nanosheets/nitrogen-doped graphene hybrid foams (MoS2/NGF) were prepared by electrostatic attraction self-assembly and subsequent freeze drying-thermal decomposition strategies using melamine-sponge-derived nitrogen-doped carbon foam as a substrate. Such a unique hierarchical framework exhibits good mechanical compressibility and provides a multidimensional charge-transport pathway between the electrode and the electrolyte. Meanwhile, few-layered MoS2 nanoplates and the presence of a high nitrogen content (11.86%) favor shortened diffusion distances and accelerate electrochemical reaction kinetics. Benefiting from the fascinating long-range interconnected structure and superb elastic property, the freestanding and binder-free MoS2/NGF anode delivers an ultrahigh specific capacity of 1246.9 mAh g(-1) at 0.1 A g(-1), excellent cycling stability (88% after 150 cycles at 0.1 A g(-1)), and an outstanding rate capacity of up to 511.1 mAh g(-1) at 2 A g(-1). The assembled soft-package battery (SPB) also demonstrates a considerable specific capacity of 712.8 mAh g(-1) after 200 cycles at 0.5 A g(-1) and an average CE of 99.5% and can constantly power green/yellow LED lamps (2.8-3.0 V/1.8-2.0 V) even under different inflection angles. Overall, the excellent compressible property and remarkable Li-ion storage performance of the MoS2/NGF electrode open up a channel in the field of intelligent wearable electronics.
