Microbatteries (MBs) and microsupercapacitors (MSCs) are primary on‐chip micropower sources that drive autonomous and stand‐alone microelectronic devices for implementation of the Internet of Things (IoT). However, the performance of conventional MBs and MSCs is restricted by their 2D thin‐film electrode design, and these devices struggle to satisfy the increasing IoT energy demands for high energy density, high power density, and long lifespan. The energy densities of MBs and MSCs can be improved significantly through adoption of a 2D thick‐film electrode design; however, their power densities and lifespans deteriorate with increased electrode thickness. In contrast, 3D architecture electrodes offer remarkable opportunities to simultaneously improve MB and MSC energy density, power density, and lifespan. To date, various 3D architecture electrodes have been designed, fabricated, and investigated for MBs and MSCs. This review provides an update on the principal superiorities of 3D architecture electrodes over 2D thick‐film electrodes in the context of improved MB and MSC energy density, power density, and lifespan. In addition, the most recent and representative progress in 3D architecture electrode development for MBs and MSCs is highlighted. Finally, present challenges are discussed and key perspectives for future research in this field are outlined.

“…Recently, novel approaches have been utilized for the formation of 3D porous substrates via metallization, for the subsequent transformation into metal phosphides etc., for example using virus templates to form Ni 3 P or Ni 2 P and Ni 5 P 4 . 239 This class of materials are treated in this review as semiconductors due to the similarity in the synthetic methods to other binary and ternary semiconductors as demonstrated in the work of Shavel and co-workers who have synthesized various colloidal TMPs of different aspect ratios. 240…”

“…In addition to the convenience in manufacturing methods, thin‐film MB possesses the potential to develop 3D structure as well. In Records’ work, [ 99 ] a virus‐templated nickel phosphide nanofoam anode was synthesized. By utilizing the advantages of nanoscale proportions and adjustable binding affinity designed by M13 bacteriophage, an electroless deposition (ELD) was conducted for its metalized process.…”

considered indispensable and stimulate great upsurge in interest on relevant researches. [1-4] Through integrating with multiple functional materials or devices, the miniaturized energy-storage device can power functional systems, such as microactuators, implantable biosensors, and wearable gadgets. [5,6] As far as the performance is concerned, the shift from disposable or nonrechargeable product to a high-energy output device or even complicated system has motivated the improvement of energy storage capability during the past decade. Generally, microsupercapacitor (MSC) possesses the advantages of fast charge/discharge rate and long cycling lifetime, making it possible for some maintenance-free wearable microelectronics and biomedical devices. [7,8] However, the energy storage gap about an order of magnitude still exists in comparison with microbattery (MB), and the insufficient energy supply restricts the widespread applications of MSC in the main power systems. [9] Serving as the primary choice for powering advanced miniaturized devices, MBs ensure sufficient energy density and maintain a stable voltage output. In general, a rechargeable battery consists of cathode, anode, and electrolyte in between, therefore it is the electrode that calls for miniaturization in size ranging from microns to centimeters. The total energy available in a MB generally depends on the active materials loaded on a certain small area. Based on this, some concepts of MB have been proposed, such as ultrathin microelectrode for high volumetric specific energy and somewhat thick microelectrode for high areal specific energy. [10,11] In terms of the dimensional ratio of MB, the thickness of microelectrode gives priority to the transport distance of ions and electrons, thus favoring the improvement in power density when compared with the macro one. [12,13] The decisive factor for the performance of MB is the reaction mechanism, and multiple battery forms have been expanded into miniaturized power supply as the supplement. Among the MBs mainly represented by lithium-ion batteries (LIBs) with organic electrolyte, various alkali metal ion batteries with abundant resources have been explored for possible substitution of lithium. [14-16] From the perspective of intrinsic safety, aqueous batteries have been developed with the merits of both inexpensive electrolyte and relatively higher power density. [17] Additionally, air batteries derived from fuel cells and ideally comprised of infinite O 2 supply for cathode reaction High-performance miniaturized energy storage devices have developed rapidly in recent years. Different from conventional energy storage devices, microbatteries assume the main responsibility for micropower supply, functionalization, and characterization platforms. Evolving from the essential goals for battery design of high power density, high energy density, and long lifetime, further practical demands for microbatteries (MBs) have been raised for the microfabrication technique and device design. Numerous studies have generally...
