Research Highlightentitled "Scalable and safer, printed Zn//MnO2 planar micro-batteries for smart electronics" [PDF] by Prof. Sang-Young Lee @UNIST, published in National Science Review.

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.
