“…[191] For practical applications in LIBs, GPEs must also have good mechanical and chemical stability, high ionic conductivity, high Li + transference numbers, and promote good interfacial contact with the electrode surfaces. [192] In recent years, there has been a great deal of research into the topic of GPEs, with studies demonstrating the application of GPEs in HV batteries with more common polymers (such as PEO, [193][194][195][196][197] PVDF, [198][199][200][201][202] and acrylate-based polymers such as polyacrylonitrile, PAN, [203][204][205][206][207] or poly(methyl methacrylate), PMMA), [208,209] as well as with more sustainable, biodegradable polymers such as cellulose [185,[210][211][212][213][214][215][216][217] or starch. [218,219] Some of these GPEs have even been capable of ionic conductivities comparable to commercial LEs (≈11.07 mS cm −1 for a 1 m LiPF 6 electrolyte in EC:DMC (1:1, v/v)).…”

Lithium‐ion batteries (LIBs) are promising candidates within the context of the development of novel battery concepts with high energy densities. Batteries with high operating potentials or high voltage (HV) LIBs (>4.2 V vs Li+/Li) can provide high energy densities and are therefore attractive in high‐performance LIBs. However, a variety of challenges (including solid electrolyte interface (SEI), lithium plating, etc.) and related safety issues (such as gas formation or thermal runaway effects) must be solved for the practical, widespread application of HV‐LIBs. Most of these challenges arise in the region between the electrodes: the electrolyte region. This review provides an overview of recent development and progress on the electrolyte region, including liquid electrolytes, ionic liquids, gel polymer electrolytes, separators, and solid electrolytes for HV‐LIBs applications. A focus on improving the safety of these systems, with some perspectives on their relative cost and environmental impact, is given. Overall, the new information is encouraging for the development of HV‐LIBs, and this review serves as a guide for potential strategies to improve their safety, allowing the development of HV‐LIBs, including solid‐state batteries, to be accelerated to practical relevance.

Batteries have many uses, so a lot of research on batteries has been developed. The part of the battery that has not been studied much is the separator, which has a crucial role as one of the battery components. The separator is the main component in the lithium-ion battery, which functions to prevent short circuits, transport free ions, and isolate electricity. The separator must have adequate porosity, high conductivity, and good thermal stability. The purpose of this research is to analyze the characteristics of the nanofiber membrane, which will be applied as a separator in lithium batteries. The material that can meet the characteristics of the battery separator is PVA-GO nanofiber. Graphene oxide was synthesized using Hummer’s method, while PVA-GO nanofiber was synthesized by electrospinning. The characterization of the separator includes conductivity, impedance, and porosity tests. The GO variations given to PVA were 0.1, 0.2, 0.3 and 0.4 gr. The resulting fiber diameter ranges from 162-194 nm, with the smallest fiber diameter being 0.2 gr GO. Nanofiber with characteristics as a membrane for separators is PVA-GO 0.4 gram, with an electrical conductivity value of 5.91×10−4 S/cm and a porosity of 42%.

“…[ 8 ] To our knowledge, this type of MOF‐natural polymer composite electrolyte is designed and prepared for the first time through electrospinning. LA is a natural polymer, it is relatively inexpensive, easily available, and environmentally friendly compared with many reported electrostatic spinning substrate materials including polyacrylonitrile (PAN) [ 2b,9 ] and polyvinylidene difluoride‐hexafluoro propylene copolymer (PVDF‐HFP). [ 10 ] Besides, the modified LA‐based electrolyte matrix obtained by electrospinning method has a 3D network structure, which is conducive to providing the required mechanical strength of electrolyte.…”

Lithium metal batteries hold promise for energy storage applications but suffer from uncontrolled lithium dendrites. In this study, a new composite membrane based on modified natural polymer and ZIF‐67 is designed and prepared by the in situ composite method for the first time. Among them, a modified natural polymer composed of lithium alginate (LA) and polyacrylamide (PAM) can be obtained by electrospinning. Importantly, the polar functional groups of natural polymers can interact by hydrogen bonding and MOFs can construct lithium‐ion transport channels. Consequently, compared with LA‐PAM electrolyte without MOF, the electrochemical stability window of ZIF‐67‐LA‐PAM electrolyte becomes wider from 4.5 to 5.2 V, and the lithium‐ion transference number ( t Li+ ) enhances from 0.326 to 0.627 at 30°C. It is worth noting that the symmetric cells with ZIF‐67‐LA‐PAM have superior stable cycling performance at 40 and 100 mA cm −2 , and a high rate at 10C and 20C for LFP cells. Besides, the cell with NCM811 high‐voltage cathode can run stably for 400 cycles with an initial discharge capacity of 136.1 mAh g −1 at 0.5C. This work provides an effective method for designing and preparing MOF‐natural polymer composite electrolytes and exhibits an excellent application prospect in high‐energy‐density lithium metal batteries.
