2020 Roadmap on Zinc Metal Batteries

Abstract Metallic zinc (Zn) is considered to be a safe and low‐cost anode for rechargeable batteries. Thus, several zinc metal batteries (ZMBs) have been well developed, i. e., zinc silver batteries, Zn−MnO 2 batteries, nickel‐zinc batteries, zinc‐air batteries and other kinds of zinc ion batteries. ZMBs are strongly correlated with electrochemistry, electrodes, electrolytes and battery structures. To support the development of this field, we herein invite some famous research experts to write this roadmap for giving some guidance in future research. The roadmap will include their research status, challenge, opportunities, and the technology advance in their fields. We expect this roadmap will produce active influence in developing green, low‐cost, safe ZMBs for our bright life in future.
