“…It was noted that PTEC possessing one more EO repeating unit in the main chains presented higher ionic conductivity and lower activation energy than those of PDEC. The high ionic conductivity up to 10 À5 S cm À1 was comparable to the PEC and P(CL-co-TMC) based polymer electrolytes reported by others [46,47,49]. The lithium ion transference number of PTECLiTFSI electrolyte estimated to be 0.39 by a steady-state current method (Fig.…”

“…These results were much superior to the PEO based lithium batteries [60] and comparable to the PEC and P (CL-co-TMC) based lithium batteries [46,47,49]. The rate capability of the Li/LiFePO 4 cell from 0.1C to 0.5C at 55 C is presented in Fig.…”

“…Inspired by the advantages of the conventional liquid carbonate electrolytes readily decomposed into polycarbonate species and resulting in stable SEI on both electrodes [2], polycarbonate-based electrolytes have recently attracted great interests in lithium battery field. Since poly(vinylene carbonate) and poly(trimethylene carbonate) based solid electrolyte were firstly reported by Shriver and Smith, respectively, fifteen years ago [44,45], Some more polycarbonate-based solid polymer electrolytes, such as poly (ethylene carbonate) [46,47], p(CL-co-TMC) [48][49][50] and poly (propylene carbonate) [51] have achieved great success in high performance of solid polymer lithium batteries. Moreover, poly (ethylene carbonate) and poly(vinylene carbonate) electrolytes possessing short ethylene oxide (EO) side chains were also reported and both revealed that longer side chains favored better ionic conductivity [52,53].…”

A B S T R A C TThe classic poly(ethylene oxide) (PEO) based solid polymer electrolyte suffers from poor ionic conductivity of ambient temperature, low lithium ion transference number and relatively narrow electrochemical window (<4.0 V vs. Li + /Li). Herein, the carbonate-linked PEO solid polymer such as poly (diethylene glycol carbonate) (PDEC) and poly(triethylene glycol carbonate) (PTEC) were explored to find out the feasibility of resolving above issues. It was proven that the optimized ionic conductivity of PTEC based electrolyte reached up to 1.12 Â 10 À5 S cm À1 at 25 C with a decent lithium ion transference number of 0.39 and a wide electrochemical window about 4.5 V vs. Li + /Li. In addition, the PTEC based Li/LiFePO 4 cell could be reversibly charged and discharged at 0.05 C-rates at ambient temperature. Moreover, the higher voltage Li/LiFe 0.2 Mn 0.8 PO 4 cell (cutoff voltage 4.35 V) possessed considerable rate capability and excellent cycling performance even at ambient temperature. Therefore, these carbonate-linked PEO electrolytes were demonstrated to be fascinating candidates for the next generation solid state lithium batteries simultaneously with high energy and high safety.

“…In addition, PTMC can also be used as monomers of copolymer to suppress crystallinity and enhance ionic conductivity. The polymerization of TMC and poly(ε‐caprolactone) (PCL) was carried out by Mindemark . The obtained PCL‐PTMC solid polymer electrolyte displayed high cation transference numbers (0.66) and much higher ionic conductivity at 23 °C.…”

Conventional liquid electrolytes based lithium-ion batteries (LIBs) might suffer from serious safety hazards. Solid-state polymer electrolytes (SPEs) are very promising candidate with high security for advanced LIBs. However, the quintessential frailties of pristine polyethylene oxide/lithium salts SPEs are poor ionic conductivity (≈10 S cm ) at 25 °C and narrow electrochemical window (<4 V). Many innovative researches are carried out to enhance their lithium-ion conductivity (10 S cm at 25 °C), which is still far from meeting the needs of high-performance power LIBs at ambient temperature. Therefore, it is a pressing urgency of exploring novel polymer host materials for advanced SPEs aimed to develop high-performance solid lithium batteries. Aliphatic polycarbonate, an emerging and promising solid polymer electrolyte, has attracted much attention of academia and industry. The amorphous structure, flexible chain segments, and high dielectric constant endow this class of polymer electrolyte excellent comprehensive performance especially in ionic conductivity, electrochemical stability, and thermally dimensional stability. To date, many types of aliphatic polycarbonate solid polymer electrolyte are discovered. Herein, the latest developments on aliphatic polycarbonate SPEs for solid-state lithium batteries are summarized. Finally, main challenges and perspective of aliphatic polycarbonate solid polymer electrolytes are illustrated at the end of this review.
