The forthcoming smart and ubiquitous electronics era has inspired the relentless pursuit of form-factor-free, high-performance power sources that can be monolithically and seamlessly integrated with electronic devices. This Perspective explores the current status and challenges of printed built-in power sources, focusing on their design and performance compatibility with newly emerging complexly structured electronic devices. The printing techniques and the ink materials and chemistry of electrodes and electrolytes are described as key enabling factors. Finally, the development direction and outlook of the printed built-in power sources are discussed.
