Special Issue Information

Dear Colleagues,

Ever since P.V. Wright first discovered the ionic conductivity of polymer complexes nearly 50 years ago, there has been intense research and development into polymer electrolytes, especially with regard to replacing organic liquid electrolytes in lithium-ion batteries.

Today, growing demand for thin, flexible, high-performance and safe lithium polymer batteries is the main concern in the industrial-scale production sector. Therefore, a polymer electrolyte is a key technology behind solid-state batteries, which determines their performance.

In this Special Issue, we invite contributions on topics that include original research data, review articles, communications, and short notes that focus on the latest developments in polymer electrolytes for energy storage applications.

We invite submissions on all aspects of polymer electrolytes, including new materials, applicable conductivity, mechanisms of ionic conductivity, ions interaction in the system, better mechanical property, electrolyte/electrode interface improvement, electrochemical working windows, etc. In addition, we welcome the latest developments in characterization methods, electrochemical performance, and other aspects of polymer electrolytes for energy storage devices.

Topics of interest include, but are not limited to:

  • polymer electrolytes
  • solid-state electrolytes
  • solid polymer electrolytes
  • gel polymer electrolytes
  • quasi polymer electrolytes
  • membranes
  • electrochemical performance
  • batteries
  • supercapacitors
  • electrochemical Sensors

The solid polymer electrolyte is a promising candidate for solid-state lithium battery because of favorable interfacial contact, good processability and economic availability. However, its application is limited because of low ionic conductivity and insufficient mechanical strength. In this study, the delicate molecular structural design was realized via controlled / “living” radical polymerization in order to decouple the trade-off between ionic conductivity and mechanical strength. The random and triblock copolymer electrolytes were designed and synthesized to investigate the influence of molecular structure on ionic conduction, while a chemical cross-linking network was constructed via a semi-spontaneous post-crosslinking reaction. Compared with a random counterpart, the triblock copolymer electrolyte presented stronger chain segment motion and a liquid-like mechanical response due to the independent ion-conducting block, resulting in significantly improved ionic conductivity (from 6.29 ± 1.11 × 10−5 to 9.57 ± 2.82 × 10−5 S cm−1 at 60 °C) and cell performance. When assembled with LiFePO4 and lithium metal electrodes, the cell with triblock copolymer electrolyte showed significantly improved rate performance (150 mAh g−1 at 1 C) and cycling life (200 cycles with 92.8% capacity retention at 1 C). This study demonstrates the advantages of molecular structure regulation on ionic conduction and mechanical support, which may provide new insights for the future design of solid polymer electrolytes.
