“…And the PVDF‐HFP/NCATP‐30 exhibited better electrochemical stability (up to 5.0 V) than PVDF‐HFP/LiTFSI. The authors explained this optimization because the interaction between 30 wt% NCATP and PVDF‐HFP/LiTFSI affected the electron transition energy level of the polymer matrix 28 . It can be considered that the nano‐NCATP introduces oxygen vacancies, which improve the stabilities of lithium salt anions and polymers through Lewis acid–base interactions.…”

With the rapid development of energy storage technology, solid‐state lithium batteries with high energy density, power density, and safety are considered as the ideal choice for the next generation of energy storage devices. Solid electrolytes have attracted considerable attention as key components of solid‐state batteries. Compared with inorganic solid electrolytes, solid polymer electrolytes have better flexibility, machinability, and more importantly, better contact with the electrode, and low interfacial impedance. However, its low ionic conductivity, narrow electrochemical stability window (ESW), and poor mechanical properties at room temperature limit its development and practical applications. In recent years, many studies have focused on improving the ionic conductivity of polymer electrolytes; however, few systematic studies and reviews have been conducted on their ESWs. A polymer electrolyte with wide electrochemical window will aid battery operation at a high voltage, which can effectively improve their energy density. Moreover, their stability toward lithium metal anode is also important. Therefore, this review summarizes the recent progress of solid polymer electrolytes on the ESW, discusses the factors affecting ESW of polymer electrolytes, and analyzes a strategy to broaden the window from the perspective of molecular interaction, polymer structural design, and interfacial tuning. The development trends of polymer electrolytes with wide electrochemical windows are also presented.

“…Benefiting from the abundant oxygen vacancies on the surface of Gd–CeO 2 , the electrochemical window of Gd–CeO 2 -PEO CPEs was increased to 5.0 V (vs. PEO-LITFSI at 4 V), and the ionic conductivity was increased 5 × 10 –4 S cm −1 . NCATP (Ce-NASICO) was synthesized by Huang et al [ 165 ]. NCATP enabled the electrolyte to exhibit an excellent antioxidant capacity (5 V) by influencing the electron-hopping energy level of PVDF-HFP.…”

With excellent energy densities and highly safe performance, solid-state lithium batteries (SSLBs) have been hailed as promising energy storage devices. Solid-state electrolyte is the core component of SSLBs and plays an essential role in the safety and electrochemical performance of the cells. Composite polymer electrolytes (CPEs) are considered as one of the most promising candidates among all solid-state electrolytes due to their excellent comprehensive performance. In this review, we briefly introduce the components of CPEs, such as the polymer matrix and the species of fillers, as well as the integration of fillers in the polymers. In particular, we focus on the two major obstacles that affect the development of CPEs: the low ionic conductivity of the electrolyte and high interfacial impedance. We provide insight into the factors influencing ionic conductivity, in terms of macroscopic and microscopic aspects, including the aggregated structure of the polymer, ion migration rate and carrier concentration. In addition, we also discuss the electrode–electrolyte interface and summarize methods for improving this interface. It is expected that this review will provide feasible solutions for modifying CPEs through further understanding of the ion conduction mechanism in CPEs and for improving the compatibility of the electrode–electrolyte interface.

other areas, and play an important role in energy storage and conversion fields. [1][2][3][4][5][6][7] Nonetheless, the constantly expanding consumption market proposes higher demands for energy density and safety of LIBs, which encourages researchers to ulteriorly improve and optimize the existing LIBs system. The regulation of high-capacity electrode materials and wide operating voltage windows becomes the key to obtaining high energy density storage. In recent years, lithium metal anode has presented great application potential owing to the excellent theoretical specific capacity (3860 mA h g −1 ) and low electrode potential (−3.04 V vs standard hydrogen electrode (SHE)). The batteries assembled by lithium metal anode and high-capacity cathodes or high voltage cathodes achieve higher energy storage compared with traditional commercial LIBs. [8][9][10][11] However, lithium metal batteries (LMBs) have been suffering from liquid organic electrolyte safety issues. Generally, the volatile and flammable liquid organic electrolytes are easy to burn and burst when the batteries receive a violent impact or damage. [12][13][14] Uncontrolled lithium dendrites growth continuously consumes the electrolytes and increases the risk of short circuits. [15][16][17][18] Besides, liquid organic electrolytes are unstable in
