▎ 摘　　要

High-performance electrode materials are developed for flexible Li-ion batteries (FLIBs) and multifunctional electronic devices. In order to solve the problem of particle aggregation and large interfacial resistance in graphene/tin oxide (SnO2) flexible electrode, ultrathin SnO2 nanorods (NR) are used to fabricate freestanding graphene/SnO2-NR (GNS/SnO2-NR) paper electrode. Owing to the superior lithium storage behavior, the short diffusion length of Li+, and uniform dispersion of SnO2-NR, the GNS/SnO2-NR exhibits high reversible capacity (940 mAh g(-1)), excellent rate capability (625 mAh g(-1) at 2000 mA g(-1)), and superior cyclic stability. Moreover, the FLIBs assembled with GNS/SnO2-NR paper electrodes can show high specific capacity and excellent cycle stability even in the state of long-term deformation. The structural design tactics point out a promising direction for the realization of mechanically compliant, ultra-stable FLIBs for the next-generation power hungry flexible/wearable electronic devices.
