演示了一种片上实验室设备，用于探测作为锂离子电池阳极的单个硅卷管的电化学动力学、电性能和结构完整性。由于扩散增强，管的循环伏安法比平面膜表现出更好的解析峰。循环后管子起皱。该管可用作其他伏安研究的有前途的超微电极。
A lab-on-chip device is demonstrated for probing the electrochemical kinetics, electrical properties, and structure integrity of a single Si rolled-up tube as the anode in lithium-ion batteries. Cyclic voltammetry of the tube exhibits better-resolved peaks than of the planar film due to the enhanced diffusion. The tube is wrinkled after cycling. The tube could be used as a promising ultra-microelectrode for other voltammetry research.
