As demand grows for safe and sustainable energy storage, zinc–iodine (Zn–I 2 ) batteries have emerged as a promising candidate due to their fast kinetics and low cost. However, zinc dendrite growth and polyiodide shuttle effects remain major barriers to long-term stability. Now, researchers from Nanjing Forestry University and Nanjing University, led by Prof. Jizhang Chen and Prof. Yagang Yao, have developed a straw-derived, anionically reinforced nanocellulose separator that effectively addresses both challenges.
