“…Excellent ion conductivity will greatly improve the rate performance and cycling performance of the battery. Gu et al [100] prepared a flexible GPE with high ionic conductivity, which can reach 1.57 × 10 −4 S/cm at 30 • C, with an ion migration number of 0.71. The semi-battery composed of it and LFP has excellent cycling performance and rate performance.…”

With the rapid development of research into flexible electronics and wearable electronics in recent years, there has been an increasing demand for flexible power supplies, which in turn has led to a boom in research into flexible solid-state lithium-ion batteries. The ideal flexible solid-state lithium-ion battery needs to have not only a high energy density, but also good mechanical properties. We have taken a systematic and comprehensive overview of our work in two main areas: flexible materials and flexible structures. Specifically, we first discuss materials for electrodes (carbon nanotubes, graphite, carbon fibers, carbon cloth, and conducting polymers) and flexible solid materials for electrolytes. A discussion of the structural design of flexible solid-state lithium-ion batteries, including one-dimensional fibrous, two-dimensional thin-film and three-dimensional flexible lithium-ion batteries, follows this. In addition, the advantages and disadvantages of different materials and structures are summarized, and the main challenges for the future design of flexible solid-state lithium-ion batteries are pointed out, hopefully providing some reference for the research of flexible solid-state lithium-ion batteries.

“…The flammability test of the gel electrolyte indicates that 40 wt% of FEPE could play the effective role on the inhibition of the combustion of the electrolyte while the common linear carbonates lead to the burning of the electrolyte. It is inspiring that this gel electrolyte maintained thermally stable at about 120 °C [119] …”

“…It is inspiring that this gel electrolyte maintained thermally stable at about 120 °C. [119] Solvate ionic liquids (SILs) like the mixture of Li salt and glymes, are usually incorporated into the gel electrolyte to improve the thermal stability because Li + and glyme will form a solvated structure, where the electron of O moves to Li + to reduce the HOMO energy level of glymes and increase their oxidative stability. With no free glymes, the oxidative and thermal stabilities will be improved to a great extent.…”

The pursuit of high energy density enables lithium metal batteries (LMBs) to become the research hotpot again. However, the safety concerns including easy leakage and inflammability of the liquid electrolyte and the performance deterioration due to the uncontrollable Li dendrites growth in liquid electrolyte limit the further development of LMBs. Gel electrolyte, the most promising alternative for the commercial liquid electrolyte, is expected to solve the dilemma faced by the liquid electrolyte because of its higher safety, good flexibility and adaptability to the electrode and high ionic conductivity comparable to that of liquid electro-lyte. Deeply understanding the characteristics and the role of the gel electrolyte in LMBs is of great importance to achieve superior electrochemical performance of LMBs. In this review, we comprehensively introduce the chemical fundamental of the gel electrolyte. On this basis, the modification strategies and the recent progress of the gel electrolyte for LMBs are systematically reviewed and particularly highlighted, which are categorized based on composition regulation, structural design and functional design. We endeavor to provide guidance for the rational design of the gel electrolyte with superior properties for LMBs.
