Abstract
Compact batteries and electronic devices offer a plethora of advantages, including space optimization, portability, integration capability, responsiveness, and reliability. These attributes are crucial technical enablers for the design and implementation of various electronic devices and systems within scientific exploration. Thus, the group harnesses additive manufacturing technology, specifically utilizing five‐axis curved‐surface multi‐material printing equipment, to fabricate aqueous zinc‐ion batteries with tungsten‐doped manganese dioxide cathode for enhanced adaptability and customization. The five‐axis linkage motion system facilitates shorter ion transportation paths for compact batteries and ensures precise and efficient molding of non‐developable curved surfaces. Afterward, the compact cell is integrated with a printed nano‐silver serpentine resistor temperature sensor, and an integrated functional circuit is created using intense‐pulse sintering. Incorporating an emitting Light Emitting Diode (LED) allows temperature measurement through variations in LED brightness. The energy storage module with a high degree of conformity on the carrier surface has the advantages of small size and improved space utilization. The capability to produce Zinc‐ion batteries (ZIBs) on curved surfaces presents new avenues for innovation in energy storage technologies, paving the way for the realization of flexible and conformal power sources.
