News Release by the EurekAlert!
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//MnO2 MBs, with outstanding performance, aesthetic diversity, flexibility and modularization, is demonstrated, based on interdigital patterns of Zn ink as anode and MnO2 ink as cathode, with high-conducting graphene ink as metal-free current collector, fabricated by industrially scalable screen-printing technique.
