CO2-sourced anti-freezing hydrogel electrolyte for sustainable Zn-ion batteries

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

“…The solvation potential of Zn in a CC-CO 2based battery (0.077 V vs. Zn 2+ /Zn) is lower than that in a CCbased battery (0.100 V vs. Zn 2+ /Zn), suggesting the smaller electrochemical polarization and a more homogeneous process of Zn 2+ embedding and stripping between the Zn anode and CC-CO 2 hydrogel electrolyte. 55,56 Meanwhile, the relationship between the hydroxyl groups on CC or -[O-CO 2 ] À groups on CC-CO 2 and Zn 2+ was explored by calculating the radial distribution functions (RDF) via MD simulation (Fig. S16c †).…”

Concepts and Emerging Trends for Structural Battery Electrolytes

“…For instance, CO 2 -derived cyclic carbonates could be used to chemically crosslink polymers (Figure 5c-iii) to improve mechanical integrity, demonstrated using polyacrylateacrylamide electrolytes for Zn-ion batteries which were amenable to twisting, compression and stretching at À 20 °C. [105] Alternatively, other than being upcycled as polymers, waste can be converted into inorganic fillers for forming composite electrolytes: sub-micron lithiophilic CaO fillers from waste eggshells could reduce PEO crystallinity, improve Li + /Na + transport, whilst simultaneously improving film tensile strength by ~60%. [48] Sustainable SPE production go beyond feedstock choice to include both catalyst selection and reaction engineering.…”

Recyclable, Fire-Resistant, Superstrong, and Reversible Ionic Polyurea-Based Adhesives

“…Carbon dioxide (CO 2 ) is one of the most attractive eco-friendly C1 resources, and its conversion and utilization are receiving global consensus in terms of achieving carbon neutrality and lowering petroleum usage. − Although the inherent thermostability and chemical inertness of CO 2 encumber its upgradation to higher value-added chemicals, numerous endeavors have been devoted to converting CO 2 into hydrocarbon fuels or polymeric materials through developing exquisite catalyst systems, , cooperating with green energies (electricity, solar, or heat), − or coupling with high-energy reactants. − The reduction of CO 2 into hydrocarbon fuels is of paramount importance to alleviate energy and environmental problems, but only a few high-value products are economically viable due to low product selectivity and unsatisfied energy efficiency. − On the other hand, copolymerization of CO 2 with epoxides, diols, diamines, or amino alcohols to synthesize functional polymers [polycarbonate (PC), polyurea (PUa), and polyurethane (PU)] is a highly rewarding CO 2 -valorization approach. − …”
