“…As we all know, the lithium-ion transference number ( t Li + ) of traditional SPEs is always below 0.3 due to its dual-ion conduction mechanism. Besides, the accumulation of anions between the electrolyte and electrode can lead to severe trouble such as concentration polarization and capacity loss. , Surely, the single-ion SPEs (SSPEs) with anions linked on the backbone settle these problems. It is worth noting that the synthesized brush after lithiation possesses the feature of SSPE.…”

Herein, we designed a series of well-defined bottlebrush-like macromolecules with short and densely grafted poly(ethylene oxide) (PEO) side chains through several controlled radical polymerization methods to prepare solid polymer electrolytes (SPEs). The PEO side chains can work as sensational conductors for lithium salt. Moreover, these macromolecules own lithium cations linked on the backbone, which can facilitate the transport of Li ions and thus improve the lithium-ion transference number. The prepared SPE exhibits a considerable ion conductivity of 4.49 × 10 −5 S cm −1 at 30 °C owing to its specific structure. Furthermore, the high capacity and excellent cycle performance demonstrate the foreseeable application of the obtained electrolyte in the lithium-ion battery.

“…In the following 1000 h, there was no short circuit happened, and the polarization remained constant, indicating the prepared electrolyte successfully inhibited the growth of lithium dendrites.

In this study, a poly(ether sulfone) is grafted with lithium 3‐chloroproanesulfonyl(trifluoromethanesulfonyl)imide (LiCPSI) through Williamson reaction to obtain a poly(ether sulfone) single‐ion polymer (PES‐LiCPSI). PES‐LiCPSI and poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) are mixed and then soaked with plasticizer (EC/PC = 1:1, v/v) to obtain a novel single‐ion gel polymer electrolyte (PES‐GPE). Its ionic conductivity of the prepared electrolyte is 7.1 × 10−5 S cm−1 at 20 °C, and the tensile strength is increased to 50.5 MPa. The lithium‐ion transfer number is up to 0.92, which should be helpful to inhibit the formation of lithium dendrites effectively. LiFePO4/PES‐GPE/Li half cells assembled with PES‐GPE possesses outstanding cycle performance and rate performance. It releases a specific capacity of 128 mAh g−1 at 0.2 C, and the capacity retention rate is as high as 97% after 370 cycles. The excellent properties of PES‐GPE demonstrate its massive capacity in high‐power and long‐cycle lithium‐ion batteries.

“…An ionic-channel-containing separator was produced by Li et al by mixing hyperbranched PMMA with poly(ether ether ketone) (PEEK) backbone possessing pendant lithium sulfonyl(trifluoromethanesulfonyl)imide groups. [109] The presence of channels was proven using TEM. The membrane revealed an ionic conductivity of 1.36 × 10 −4 S cm −1 at 25 °C and 1.01 × 10 −3 S cm −1 at 90 °C, and a high lithium transference number of 0.94 (25 °C), utilizing PC as a plasticizer.…”

both large-and small-scale energy storage, ranging from large pumped hydroelectric storage to very small battery cells for handheld devices.Secondary batteries are among the more promising energy storage technologies, with a wide range of applications. [4] Since the development of the lead acid battery in the second half of the 19th century (Gaston Planté, 1860), a broad range of batteries has been invented. [5] Notable examples are the nickel/cadmium cell (1899) [6] and the lithium-ion battery, which was developed in the 1970s. [7] Today, batteries are omnipresent in the everyday lives of a large part of the world's population. They find application in numerous fields, ranging from handheld or portable devices to electric vehicles (including vehicles with combustion engines) to large-scale energy storage for renewable sources. [8] Each field has unique requirements for the applied batteries, therefore different battery types have been developed to meet the demands.The most dominant type of secondary batteries for modern devices is the lithium-ion battery. Lithium-ion batteries possess high energy densities, good rate capabilities, and a long cycle life. Since their commercialization in 1991, they have been applied in many portable devices, electric vehicles and even in large-scale energy storage systems. [7] Since 2000, the share of the worldwide produced lithium for application in batteries (35% of the total production in 2015) has increased by 20% per year. [9] Another, less known battery type is the redox-flow battery (RFB). With their independent scalability of capacity and power, they are in particular interesting for large-scale storage of renewable energy with regard to grid stability. [10] A recent, so far not commercially available type of batteries is the organic battery. Here, an organic compound (small molecule or polymer) is responsible for charge storage. Organic batteries offer high rate capabilities, cheap starting materials, and are less environmentally challenging compared to metalbased batteries. Possible fields of application are small, lightweight, and easily recyclable products. [11] None of the above-mentioned batteries would work without polymers. Polymers can be found in the electrodes, where they act as binders, ensuring a good adhesion and contact among the different materials. Furthermore, many membranes are based on polymers. Here, the macromolecules have to be ionconducting as well as mechanically and chemically robust. In addition, organic batteries rely on polymeric active materials. This review discusses the diverse possibilities polymers haveIn the light of an ever-increasing energy demand, the rising number of portable applications, the growing market of electric vehicles, and the necessity to store energy from renewable sources on large scale, there is an urgent need for suitable energy storage systems. In most batteries, the energy is stored by exploiting metals or metal-ion-based reactions. However, nearly every modern battery would not function without the help of polymer...
