Microbatteries are indispensable to power emerging miniaturized electronics for medical, environmental, or stealth applications. However, they are usually fabricated by additive printing processes, limiting their sizes and energy densities. Here, we develop a subtractive manufacturing process by slicing assembled thin-film zinc-ion batteries into microcells in batches using optimized preintercalated MnO2 (K0.27MnO2·0.54H2O, KMO) as cathodes. The composite cathode consisting of KMO and reduced graphene oxide (rGO) delivers a high specific capacity of 323.4 mAh g–1 at 0.1 A g–1 with no capacity loss after 750 cycles at 1 A g–1. Such a high performance renders Zn//KMO/rGO solid-state microbatteries with areal energy densities of 0.244 mWh cm–2, which are comparable to those of the state of the art. This microbattery, with an area of 4 × 4 mm2 and a thickness of 0.56 mm, can be modularly arranged on a chip for a stretchable energy-supply circuit, which can be closely attached to human skin.

“…Furthermore, the footprint of a ZMB full cell with twin Swiss‐roll electrodes encapsulated in a polymer box was reduced to 0.11 mm 2 . [ 97 ] Microscale holes are patterned into the Swiss‐roll current collectors to allow for the complete penetration of the electrolyte into the compact Swiss‐roll (Figure 6f–i). The Swiss‐roll ZMB shows a high energy density of 181 µWh cm −2 and a lifetime energy of 26 µWh, which is expected to power a low‐power (16 nW) temperature sensing microsystem with data processing capability for about 2 months with one charge.…”

As intelligent microsystems develop, many revolutionary applications, such as the swallowing surgeon proposed by Richard Feynman, are about to evolve. Nonetheless, integrable energy storage satisfying the demand for autonomous operations has emerged as a major obstacle to the deployment of intelligent microsystems. A reason for the lagging development of integrable batteries is the challenge of miniaturization through microfabrication procedures. Lithium batteries, generated by the most successful battery chemistry, are not stable in the air, thus creating major manufacturing challenges. Other cations (Na+, Mg2+, Al3+, K+) are still in the early stages of development. In contrast, the superior stability of zinc batteries in the air brings high compatibility to microfabrication protocols and has already demonstrated excellent practicability in full‐sized devices. To obtain energy‐dense and high‐power zinc microbatteries within square‐millimeter or smaller footprints, sandwich, pillar, and Swiss‐roll configurations are developed. Thin interdigital and fiber microbatteries find their applications being integrated into wearable devices and electronic skin. It is foreseeable that zinc microbatteries will find their way into highly integrated microsystems unlocking their full potential for autonomous operation. This review summarizes the material development, configuration innovation, and application‐oriented integration of zinc microbatteries.

“…[6][7][8] A notable recent achievement is the use of a 3D selfassembly process at the microscale, also known as micro-origami, to self-fold thin-film batteries into micro-Swiss-roll devices less than one square millimeter across but that offer high energy density. [4,9,10] However, the lack of solid or quasi-solid electrolytes still denies the integration of micro-Swiss-roll energy storage devices into tiny systems. Addressing this challenge requires multidisciplinary efforts coming transversely from materials science, [11] electrochemistry, [12] and microelectronics.…”

Tiny autonomous systems less than 1 mm across need small energy storage to satisfy the demand for temporary pulse power and consistent power supply. A battery or supercapacitor alone cannot meet both requirements. Integration of battery and supercapacitor is an alternative, but it introduces a device (supercapacitor) that is not frequently invoked but requires substantial space. Herein, a submillimeter (0.42 mm2) high‐power supercapacitor with an additional function, namely, an on‐chip integrated probe for biomolecule detection is created. The dual‐function device is directly used in the liquid electrolyte, and its Swiss‐roll geometry allows for operation in a minimum 12‐nL electrolyte. The micro‐Swiss‐roll supercapacitor delivers a power density of 911 mW cm−2 and displays a 98% capacitance retention over 10 000 cycles. The biomolecule probe achieves a sensitivity of 230–262 µA mm−1 with a limit of detection of 0.4–0.5 × 10−3 m for the proof‐of‐concept target, the neurotransmitter dopamine. The biomolecule probe achieves a 230–262 µA mm−1 sensitivity with a limit of detection of 0.4–0.5 × 10−3 m for the proof‐of‐concept target, the neurotransmitter dopamine, along with selectivity in the presence of ascorbic acid. The independent dual function provides a promising route toward the full‐time use of dust‐sized supercapacitors integrated into submillimeter functional systems.
