Abstract
Abstract Emerging markets for wearable electronics have stimulated a rapidly growing demand for the commercialization of flexible and reliable energy storage and conversion units (including batteries, supercapacitors, and thermoelectrochemical cells). 3D printing, a rapidly growing suite of fabrication technologies, is extensively used in the above‐mentioned energy‐related areas owing to its relatively low cost, freedom of design, and controllable, reproducible prototyping capability. However, there remain challenges in processable ink formulation and accurate material/device design. By summarizing the recent progress in 3D‐printed wearable electrochemical energy devices and discussing the current limitations and future perspectives, this article is expected to serve as a reference for the scalable fabrication of advanced energy systems via 3D printing.
