A novel polymer electrolyte with in situ polymerization and a high concentration of lithium salts for lithium metal batteries

Abstract

A novel polymer electrolyte is prepared by in-situ polymerization for lithium metal batteries. The polymer electrolyte with in-situ polymerization can maintain good inter-facial contact property between the electrodes and electrolyte....

Gel polymer electrolytes for rechargeable batteries toward wide-temperature applications

“…7(a)-(c)). [173][174][175] Another critical feature brought by concentration alternation involves ionsolvation structure and the interfacial chemistry (Fig. 7(d)).…”

Polymer design for solid-state batteries and wearable electronics

“… 34 Such low values are a problem because the movement of charge in opposite directions leads to polarization and large overpotentials in the cell. These low values have been largely circumvented through high-salt loadings (>50 wt%), 25 anion trapping strategies 79 and covalent attachment of the anion to the polymer backbone (single-ion conductors). 80 Such strategies, however, usually result in decreased stability for high salt systems and lower ion conductivity for the anion trapping and single-ion conductors.…”

“…16,24 Polymers, on the other hand, have the advantages of lightweight, tuneable mechanical performances, including high exibility and elasticity plus advanced self-healing behaviours as well as ease of thin-lm manufacture. 25,26 Whilst stability against reactive Li-metal may still pose uncertainties, SPEs are also attractive for other next-generation electrodes such as ultrahigh capacity silicon anodes (4200 mA h g −1 ). These undergo especially large volume changes of up to 300% during charge-dischargecycles and thus require exible electrolyte designs.…”

In situ synthesis of cross-linking gel polymer electrolyte for lithium metal batteries

“…The precursor materials chosen for in situ polymerization have certain requirements, including mild initiation conditions and selected reaction process with little gas production [18][19][20]. During in situ polymerization process, monomers or oligomers would undergo transformation into large molecular triggered by light exposure or thermal heating [21][22][23][24]. By employing the in situ polymerization technique, SPE with excellent interface performance, high energy density, and enhanced safety can be obtained [25].…”
