Ion gels controlled by network defects were fabricated using TetraPEG prepolymers and Li salt/IL electrolyte, showing higher ionic conductivity than IL solution. The electrode reaction at the graphite negative electrode was strongly influenced by network defects in the gels, leading to a linear increase in charge/discharge capacities with the proportion of network defects.
We report network defect-controlled ion gels fabricated from two key materials: tetra-arm poly(ethylene glycol) (TetraPEG) prepolymers and a lithium (Li) salt/ionic liquid (IL) electrolyte. The resulting TetraPEG ion gels exhibited higher ionic conductivity than the corresponding IL solution, and the network defects in the gels strongly affected the electrode reaction (Li-ion insertion/desertion reaction at the graphite negative electrode). Specifically, the charge/discharge capacities increased linearly with the proportion of network defects.
