Abstract Freestanding membrane built from interwoven carbon fibers with encapsulated liquid gallium (Ga) nanodroplets has been demonstrated via the ultrasonic cell disrupting and electrospinning approaches along with a subsequent annealing process. Employing this membrane as a freestanding anode for lithium storage, the severe volume changes of Ga can be effectively accommodated due to the unique encapsulated 3D network structure. As a result, the membrane exhibits superior electrochemical performance, including high reversible capacity (450 mAh g−1), enhanced cycling stability (247 mAh g−1 at 0.65 A g−1 over 250 cycles), as well as good rate performance (200 mAh g−1 at 2 A g−1).

封装在碳纳米纤维中的液态镓用于高性能锂存储

摘要 已经通过超声波细胞破碎和静电纺丝方法以及随后的退火过程证明了由交织碳纤维与封装的液态镓 (Ga) 纳米液滴构成的独立膜。将这种膜用作锂存储的独立阳极，由于独特的封装 3D 网络结构，可以有效地适应 Ga 的剧烈体积变化。因此，该膜表现出优异的电化学性能，包括高可逆容量（450 mAh g-1）、增强的循环稳定性（247 mAh g-1 在 0.65 A g-1 下 250 次循环）以及良好的倍率性能（ 2 A g-1 时为 200 mAh g-1）。
