Plant-Based Hydrogel Tames Zinc Dendrites, Pushes Aqueous Batteries Past 1 000 Stable Cycles (IMAGE)
Caption
A multiscale cellulose hydrogel reported in the Journal of Bioresources and Bioproducts delivers 10.27 mS cm-1 ionic conductivity and a 0.84 Zn2+ transference number while suppressing dendrites and hydrogen evolution. The separator-free, biodegradable film cuts separator cost twelve-fold and enables flexible pouch cells that survive 2 kg bending loads, offering a scalable path for safe, low-cost aqueous zinc-ion batteries.
