Abstract A new series configuration without internal connection was designed and planar on-chip micro-supercapacitors with series structure were fabricated by liquid-air interface self-assembly and photolithography. Compared with the series structures of internal metal connection and graphene connection, the planar on-chip micro-supercapacitors with no internal connection greatly reduced internal resistance and saved device volume. The planar on-chip micro-supercapacitors with no internal connection were provided with high output voltage of 2 V, time constant of 0.042 ms, stack capacitance of 27.30 F cm-3 and capacitance retention of 89% after 10000 cycles of charging and discharging at scan rate of 100 V s-1.

无内部连接的基于石墨烯的集成平面片上微型超级电容器

摘要 设计了一种新型的无内连接串联结构，采用液-气界面自组装和光刻技术制备了具有串联结构的平面片上微型超级电容器。与内部金属连接和石墨烯连接的串联结构相比，无内部连接的平面片上微型超级电容器大大降低了内阻，节省了器件体积。没有内部连接的平面片上微型超级电容器具有 2 V 的高输出电压、0.042 ms 的时间常数、27.30 F cm-3 的堆叠电容和在 10000 次充放电循环后电容保持率为 89%扫描速率为 100 V s-1。
