Zn-Air Batteries: All-Hand-Drawn Zn-Air Batteries: Toward User-Customized On-the-Fly Power Sources (Adv. Sustainable Syst. 5/2018)

In article number 1700132, Sang-Young Lee and co-workers demonstrate all-hand-drawn primary zinc (Zn)-air batteries as a new class of user-customized, on-the-fly power sources. The all-hand-drawn Zn-air batteries are fabricated directly on A4 paper under ambient conditions by using a simple pen/pencil-based hand drawing technique, exhibiting their unique “on-demand”/“on-site” fabrication. The all-hand-drawn Zn-air batteries are aesthetically unitized with arbitrary-shaped IoT devices.
