英文摘要To meet the increasing demand of flexible and wearable electronic devices, a novel injection molding method is established to prepare flexible electrodes with controllable shapes such as film, bowl, wire, etc. It overcomes the materials limitation for traditional methods and could easily create flexible and shapeable electrodes based on 0-D active materials, even with ultra-high loadings and excellent electrochemical performance. Taking flexible and shapeable S/C electrodes as a model, sulfur loadings 24 mg cm(-2) based on 30 nm S/C particles are, for the first time, successfully achieved. It can deliver ultra-high an areal capacity of 27.1 mA h cm(-2) and a capacity retention of 64.1% after 100 cycles with low electrolyte to sulfur ratio (E/S) of 5.3 mu L mg(-1). In addition, flexible and shapeable Li-ion battery electrodes based on 17 mg cm(-2) 0-D Li3V2(PO4)(3) (LVP) electrode could also be obtained, achieving excellent C-rate performance and cycling stability, which is 94 mA h g(-1) at 5C and nearly 100% capacity retention at 1C during 100 cycles. The results provided a versatile and universal way to create flexible and shapeable electrodes for a variety of energy storage devices.
