Batteries: Recent Advances in Flexible Zinc‐Based Rechargeable Batteries (Adv. Energy Mater. 1/2019).

Flexible Zn‐based batteries are emerging candidates for wearable electronics owing to the natural merits of zinc, such as environmental friendliness and low cost. In article number 1802605 by Cheng Zhong, Jun Lu, and co‐workers, the challenges of developing flexible Li‐ion batteries are presented. Thereafter, a brief overview of recent progress in the development of flexible Zn‐based rechargeable batteries from the perspective of energy density, rechargeability, flexible electrolytes, and some other issues that remain to be addressed, are highlighted.
