“…Increase in conductivities of conductive polymers with increasing temperature is a typical behavior (30). Becoming the resistivity of the composite stable more rapidly according to pure PPy could be a result of the plasticizing effect of water molecules which is highly absorbed by zeolite.…”

Composite of polypyrrole (PPy) and natural zeolite (NZ) was prepared by chemical polymerization of pyrrole in the presence of zeolite dispersed in aqueous medium. Results of elemental analysis showed that the percentage amount of dopant in the structure of composites was reached a value of as high as 35.5%. PPy content and conductivity of composites obtained under the tried polymerization conditions changed between 8% and 55% and 3.0 × 10 −3 and 17 × 10 −2 S/cm, respectively. The conductivity of composites prepared by chemical polymerization was higher than those prepared by physically mixing of the components of composite. Change in the resistivity of PPy/NZ composite monitored by heating-cooling cycles in the temperature range of 0-60 • C repeated five times, we noticed that the composite showed more repeatable results compared to that of its conductive component PPy. Size distribution analysis showed that particle size of NZ in the composite increased as a result of PPy coating and particle size of composite containing 43% PPy reached up to 30 μm of d(0.9). FTIR, TGA, XRD and SEM techniques were also used for the characterization of PPy/NZ composite.

“…Such ionic conductivity was comparable to other reported ones listed in Table S2. Furthermore, the activation energy calculated by the Arrhenius equation − was decreased from 1.04 to 0.56 eV after the incorporation of 40% Li-IL@HKUST-1 (below 60 °C, Table S3), superior to the reported values in the range of 0.98–1.23 eV . Noted that we have tried to introduce a much higher ratio (e.g., 50% and 60%) of Li-IL@HKUST-1 into PEO-based polymer electrolyte.…”

Poly(ethylene oxide) (PEO)-based polymer electrolytes have shown extraordinary promise for all-solid-state lithium batteries; however, the practical application was severely restricted by their low ionic conductivity. In this work, the robust pores of HKUST-1(Cu) were first filled by a lithium-containing ionic liquid (Li-IL) to form ion-conductive Li-IL@HKUST-1. Subsequently, flexible composite polymer electrolytes (CPEs) were constructed via a solution-casting approach upon the incorporation of Li-IL@HKUST-1 with PEO. The as-synthesized CPE membrane showed a high ionic conductivity of 1.20 × 10–4 S cm–1 at 30 °C compared to 9.76 × 10–6 S cm–1 for the PEO-only electrolyte. Furthermore, the assembled LiFePO4/Li solid-state batteries delivered a stable reversible capacity of 136.2 mAh g–1 with a capacity retention of 92% after 100 cycles at a high current density of 1 C (60 °C). The excellent electrochemical performance was mainly attributed to the combination of Li-IL@HKUST-1 and the PEO matrix, which effectively reinforced the polymer matrix and facilitated the fast transport of lithium ions. The present research provides an effective strategy for building high-performance all-solid-state lithium batteries.
