Synergistic Manipulation of Zn ²⁺ Ion Flux and Desolvation Effect Enabled by Anodic Growth of a 3D ZnF ₂ Matrix for Long‐Lifespan and Dendrite‐Free Zn Metal Anodes

Technological improvements in rechargeable solid-state batteries are being driven by an ever-increasing demand for portable electronic devices. Lithium-ion batteries are the systems of choice, offering high energy density, flexible and lightweight design, and longer lifespan than comparable battery technologies. We present a brief historical review of the development of lithium-based rechargeable batteries, highlight ongoing research strategies, and discuss the challenges that remain regarding the synthesis, characterization, electrochemical performance and safety of these systems.
