Recyclable and CO₂-retardant Zn–air batteries based on CO₂-decorated highly conductive cellulose electrolytes

Abstract

Ever-growing fossil fuel consumption and portable electronic device proliferation have caused numerous environmental challenges in terms of producing massive carbon dioxide (CO2) emissions and end-of-life wastes. Incorporating naturally abundant resources...

Sustainable zinc–air battery chemistry: advances, challenges and prospects

“…Li et al soaked the poly-2-acrylamide-2-methylpropanesulfonic acid (AMPS)/PAM hydrogel in KOH electrolyte containing a certain concentration of DMSO and obtained an organohydrogel electrolyte. 300 The organohydrogel electrolyte enhanced the frost resistance and endowed good low-temperature ionic conductivity. Zhou and coworkers prefixed CO 2 on the alkaline PVA polymer chain via ionization in conjunction with the strong organic base tetramethylguanidine (TMG), obtaining a novel CO 2 -tolerant PVA-TMG GPE.…”

Advances in polymer electrolytes for solid-state zinc–air batteries

“…Chen et al 30 were able to successfully resist CO 2 through the chemical method of prefixing CO 2 onto the PVA chain. Zhou et al 144 developed a high-performance quasi-solid electrolyte by combining CO 2 fixation with cellulose (CC-CO 2 hydrogel electrolyte). The conductivity of the CO 2 -modified quasi-solid electrolyte is significantly improved, which can effectively inhibit the CO 2 poisoning of the electrolyte.…”
