Lignin-Based Solid Polymer Electrolytes: Lignin-Graft-Poly(ethylene glycol)

Inside Cover: In article number 2000428, Hoyong Chung, Daniel Hallinan Jr., and coworkers graft-copolymerized biomass lignin with poly(ethylene glycol) through eco-friendly and low energy-consuming photo-redox catalysis that can be performed under natural sunlight. The new solid polymer electrolyte is designed to be used for safe battery applications. With enhanced mechanical strength and thermal stability, the new polymer demonstrates excellent ionic conductivity at both ambient and elevated temperatures.
