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

Abstract

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.

Enhanced ionic conduction in composite polymer electrolytes filled with plant biomass “lignin”

“…[20][21][22] Moreover, the previous studies on electrolytes for batteries only focused on lignin that needs complex graft copolymerization. 23,24 Furthermore, all the applied lignin uses conventional extraction procedures, such as thermochemical treatment. 24,25 Recently, we proposed a novel lignin extraction process without high temperature and toxic reagents, in which wettype ultrafine bead milling and enzymatic saccharification are used for the simultaneous enzymatic saccharification and comminution (SESC) of plants.…”

Lignin for energy applications – state of the art, life cycle, technoeconomic analysis and future trends

“…Newly synthesized lignin-graft-PEG combines the mechanical and thermal properties of lignin with the flexibility and superior ionic conductivity of PEG. 167 The solid electrolytes served as a binder and an ion conductor with the capability of suppressing dendrite formation. While all these findings show high promise for lignin, the requirement of synthetic polymer blends dilutes the eco-friendliness and performance of the lignin-based battery component.…”
