| 英文摘要 | High-performance flexible lithium-ion batteries are leading candidates for power sources of wearable and foldable electronics. As a result, it is vital to design freestanding electrodes with high capacity and stability. Herein, we develop a novel strategy to significantly improve the performance of freestanding anodes by artificially introducing an ultrathin but robust interface based on polyacrylamide/gelatin gel with excellent mechanical durability and ionic conductivity. The artificial interface suppresses the formation of a thick solid electrolyte interface, facilitates charge transfer processes and strengthens the integrity of the electrode. Benefitting from these merits, our freestanding anode made of the nano/microstructured NiFe2O4-CNTs composite achieves a high capacity of 612 mA h g(-1) based on the total mass of the electrode. The high-performance freestanding anode further enables a stable output capacity of 140 mA h g(-1) over 1000 charge/discharge cycles for a full battery using commercial LiMn2O4 as the cathode material. Meanwhile, the excellent rate performance of the freestanding anode guarantees high energy output up to 255 W h kg(-1) at a high power density of 12 000 W kg(-1) for the full battery. Moreover, the intrinsic flexibility of the freestanding electrodes enables the fabrication of a flexible lithium-ion battery, which is highly stable even under harsh mechanical deformation. This work provides a new perspective to fabricate next-generation flexible batteries with high energy density and excellent stability, further advancing the development of foldable and wearable electronics toward practical applications. |
