Solid-state zinc-ion batteries (SSZIBs) are receiving much attention as low-cost and safe energy storage technology for emerging applications in flexible and wearable devices, and grid storage. However, the development of SSZIBs faces many challenges from key battery materials development to structure design. Herein, we review the most recent progress in the development of polymer electrolytes, cell chemistry and configuration, and demonstration of SSZIBs. In conclusion, perspectives for future research in materials, interface, and assessment of SSZIBs are discussed.
