The rapid development of printed and microscale electronics imminently requires their compatible micro-batteries (MBs) with high performance, applicable scalability, and exceptional safety, but facing great challenges from the ever-reported stacked geometry. Herein, the first printed planar prototype of aqueous-based, high-safe Zn//MnO ₂ MBs, with outstanding performance, aesthetic diversity, flexibility and modularization, is demonstrated, based on interdigital patterns of Zn ink as anode and MnO ₂ ink as cathode, with high-conducting graphene ink as metal-free current collector, fabricated by industrially scalable screen-printing technique.

This work was highlighted by the famous media of EurekAlert.
