The architecture of electrodes plays a pivotal role in the transfer and transportation of charges during electrochemical reactions. Selecting optimal electrode materials and devising well-conceived electrode structures can substantially enhance the electrochemical performance of devices. This manuscript leverages 3D printing technology to fabricate asymmetric supercapacitor devices featuring regular layered configurations. By investigating the impact of various materials on the internal architecture of printed electrodes, we establish a stratified electrode structure with an orderly arrangement, thereby significantly improving asymmetric charge transfer between electrodes. The application of 3D printing technology to construct electrode structures effectively mitigates the agglomeration of electrode materials. The 3D-printed VCG//MXene devices demonstrate exceptional areal capacitance (205.57 mF cm) and energy density (60.03 μWh cm), with a power density of 0.174 W cm. Consequently, selecting appropriate materials for fabricating printable electrode structures and achieving efficient 3D printing is anticipated to offer novel insights into the construction and enhancement of miniature asymmetric micro-supercapacitor (MSCs) devices.
电极结构在电化学反应过程中的电荷转移和输运中起着关键作用。选择最佳电极材料并设计出构思精巧的电极结构能够显著提高器件的电化学性能。本论文利用3D打印技术制造具有规则分层结构的非对称超级电容器器件。通过研究各种材料对打印电极内部结构的影响，我们建立了一种排列有序的分层电极结构，从而显著改善了电极之间的非对称电荷转移。应用3D打印技术构建电极结构有效地减轻了电极材料的团聚。3D打印的VCG//MXene器件展现出优异的面积电容（205.57 mF cm）和能量密度（60.03 μWh cm），功率密度为0.174 W cm。因此，选择合适的材料来制造可打印电极结构并实现高效3D打印有望为微型非对称微型超级电容器（MSC）器件的构建和性能提升提供新的见解。
