Summary: This paper reports a highly-concentrated FSI-based ternary gel polymer electrolyte (TGPE) with high lithium-ion conductivities, wide electrochemical stability, and superior compatibility with lithium metal electrode. The TGPE enables stable Li plating and stripping processes, as well as high discharge capacity of a Li||Li(Ni0.6Mn0.2Co0.2)O2 cell at ambient temperatures. This study not only provides safe and highly conductive polymer electrolytes but also enhances our understanding of the role of FSI anions in high-energy lithium metal batteries.

Summary: As demand for electrical energy storage devices increases, researchers are studying different electrolytes for safer and longer-lasting gel polymer electrolytes (GPEs) to replace liquid electrolytes facing fire or explosion issues. However, the poor electrochemical properties of GPEs limit their commercialization in all-solid-state energy storage devices. To address this problem, epoxy/poly(ethylene glycol) (PEG)-based double network electrolytes (DNEs) containing a mixture of lithium salt and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) are designed to enhance the electrochemical properties. The synthesized epoxy/PEG-based DNE has higher mechanical strength and outstanding ionic conductivity, leading to improved performance in all-solid-state supercapacitors compared to traditional single network electrolytes (SNEs).

Summary: Flexible solid-state Lithium-sulfur batteries (FSSLSBs) are crucial for industries requiring low-cost batteries with good mechanical properties, high capacity, and high energy densities. However, commercialization of FSSLSBs is hindered by challenges in creating high-loading flexible sulfur cathodes, optimizing solid-state electrolytes (SSE) designs, suppressing Li metal dendrite growth, and optimizing cell geometries for flexibility. This review highlights recent progress in these aspects and discusses future research directions for FSSLSBs.

Summary: In this study, gel polymer electrolytes (GPEs) based on PVdF-HFP, 1 M LiPF6 in EC/DMC (LP30), and [Py-14]PF6 were developed to enhance the safety and electrochemical performance of high voltage lithium batteries. The GPEs demonstrated nonflammable character and mechanical stability through physical crosslinks, and showed improved lithium ion conduction property. When using LP30 with 30 wt% [Py-14]PF6, the lithium metal batteries exhibited enhanced electrochemical performance with high coulombic efficiency and specific capacity retention throughout 150 cycles. This suggests that [Py-14]PF6 is a promising additive for extending battery life.

Summary: A new lithiated-interpenetrating network gel-polymer electrolyte (LIPN-GPEs) has been designed and fabricated by ultraviolet-irradiation radical polymerization. The LIPN-GPEs exhibit excellent mechanical strength and flexibility due to the interpenetrating network, which eliminates volume changes of the lithium anode during the deposition/stripping process. Furthermore, the LIPN-GPEs demonstrate better self-supporting nature, high ionic conductivity, and stable SEI composition, making them ideal for lithium metal batteries. The study also shows that the LIPN-GPEs have wider electrochemical window, exceptional thermal stability, and good high-voltage resistance, indicating their potential in wearable devices.

Summary: In this study, an interdigitated Li-solid polymer electrolyte framework (I-Li@SPE) is designed to enhance the interfacial integrity of all-solid-state batteries. The results show that the 3D Li-SSE interfacial contact in the I-Li@SPE remains smooth and intact after repeated cycling, while the planar contact fails to maintain stability. COMSOL simulation indicates that the I-Li@SPE reduces local current densities by more than 40% and moderates interfacial variation by more than 50%. Consequently, the I-Li@SPE achieves high critical current density and promising high areal capacity cycling. This work presents a new structure for the fabrication of Li-SSE composites and holds great potential for high-capacity solid-state Li batteries.
