Practical considerations for enabling Li|polymer electrolyte batteries

Computational approach inspired advancements of solid-state electrolytes for lithium secondary batteries: from first-principles to machine learning

“…Compared to liquid and ceramic electrolytes, PEs, including solid polymer electrolytes (SPEs) and gel polymer electrolytes (GPEs), offer several advantages such as ease of processing, availability, and operational safety. 136,137 However, their widespread adoption is hindered by their relatively low ionic conductivity (around 10 −4 S cm −1 at 25 °C) and low Li + transference number (around 0.3). 138 Overcoming these limitations is crucial to match the performance of state-of-the-art electrolytes, and it requires a deep understanding of the Li-ion conduction mechanisms in polymer electrolytes.…”

Constructing host–guest recognition electrolytes promotes the Li+ kinetics in solid-state batteries

“…1 Among the various solid-state electrolytes (SSEs), solid polymer electrolytes (SPEs) are considered to be capable materials for large-scale industrialization due to their advantages of high flexibility and good interfacial contact. 2,3 However, SPEs are restricted by their slow ionic kinetics and low-selectivity Li + transport, 4,5 which lead to non-ideal overall performance of the batteries. In addition, the instability of SPEs under high voltage has seriously hindered their practical applications.…”

“…11 However, the low ionic conductivity of SPEs at room temperature (B10 À5 S cm À1 ) restricts their application. [12][13][14] Furthermore, polymer materials, in general, exhibit poor thermal, mechanical and electrochemical stabilities, making them unsuitable for practical applications.…”
