The performance of pseudocapacitive electrodes at fast charging rates are typically limited by the slow kinetics of Faradaic reactions and sluggish ion diffusion in the bulk structure. This is particularly problematic for thick electrodes and electrodes highly loaded with active materials. Here, a surface‐functionalized 3D‐printed graphene aerogel (SF‐3D GA) is presented that achieves not only a benchmark areal capacitance of 2195 mF cm−2 at a high current density of 100 mA cm−2 but also an ultrahigh intrinsic capacitance of 309.1 µF cm−2 even at a high mass loading of 12.8 mg cm−2. Importantly, the kinetic analysis reveals that the capacitance of SF‐3D GA electrode is primarily (93.3%) contributed from fast kinetic processes. This is because the 3D‐printed electrode has an open structure that ensures excellent coverage of functional groups on carbon surface and facilitates the ion accessibility of these surface functional groups even at high current densities and large mass loading/electrode thickness. An asymmetric device assembled with SF‐3D GA as anode and 3D‐printed GA decorated with MnO2 as cathode achieves a remarkable energy density of 0.65 mWh cm−2 at an ultrahigh power density of 164.5 mW cm−2, outperforming carbon‐based supercapacitors operated at the same power density.

Microsupercapacitors (MSCs) are integrated into microdevices or chip‐based systems to store energy and power the chip efficiently, as they present excellent performance capabilities including high power density, fast charge/discharge rate, and long cycle time. Providing sufficient surface area and high electric conductivity are effective ways to enhance ion diffusion and charge transportation in electrodes, which in turn leads to high performance behavior. Herein, the novel progress of on‐chip MSCs in the past few years ranging from active materials synthesis to high‐resolution fabrication techniques is summarized, and the strategies to enhance the performance of MSCs are focused upon. From conventional materials to nanocomposite hybrid structures, the main active materials for MSC electrodes and the related fabrication techniques are reviewed in detail according to their different electrochemical performance. It is concluded that hierarchical porous‐structured materials and high‐resolution fabrication processes are of great importance in constructing high‐performance devices, which also demonstrates the future developing direction of on‐chip energy devices. The new developments of fabrication technologies such as microfabrication, laser direct writing, and inkjet printing are also discussed to show their advantages in forming high‐performance electrodes.

A growing demand for miniaturized biomedical sensors, microscale self‐powered electronic systems, and many other portable, wearable, and integratable electronic devices is continually stimulating the rapid development of miniaturized energy storage devices (MESDs). Miniaturized batteries (MBs) and supercapacitors (MSCs) were considered to be suitable energy storage devices to power microelectronics uninterruptedly with reasonable energy and power densities. However, in addition to similar challenges encountered with electrode materials in conventional energy storage devices, their performances are also greatly affected by microfabrication technologies, as well as the challenges of how to realize stable and high‐performance MESDs in such a limited footprint area. Benefiting from the unique architectural engineering of two‐dimensional materials and the emergence of precise and controllable microfabrication techniques, the output electrochemical performances of MSCs and MBs are improving rapidly. This minireview summarizes recent advances in MSCs and MBs built from two‐dimensional materials, including electrode/device configuration designs, material synthesis, microfabrication processes, smart function incorporations, and system integrations. An introduction to configurations of the MESDs, from linear fibrous shapes, planar sandwich thin‐film or interdigital structures, to three‐dimensional configurations, is presented. The fundamental influences of the electrode material and configuration designs on the exhibited MB/MSC electrochemical performances are also highlighted.
