“…As shown in Figure 4, the liquid-state precursors, containing monomers and Li salts, can permeate into the voids that exist in the electrolyte/electrode interfaces and are polymerized under heating, irradiation, or electrochemical treatment to obtain an efficiently dispersed SPE. [49][50][51][52] Thus, a continuous ion-transport pathway can be built among the interface by such in situ polymerized SPE. Moreover, the losing contacts caused by active materials' volume changes during electrochemical cycling can also be alleviated to a great extent.…”

Higher energy storage in the limited space of lithium batteries always brings more safety hazards. To address this issue, the utilization of solid electrolyte to replace the liquid one is a promising strategy. However, the sluggish charge transfer and poor interfacial compatibility between solid electrodes and solid electrolyte severely hinder the performance of high-energy-density solid-state lithium batteries. Thus, in this Perspective, the bottlenecks and the related solutions regarding organic/inorganic composite electrolyte, lithium-metal anode, and high-voltage cathode are focused on, and compatible interface engineering is presented. Aiming at the commercialization of high-energy-density solid-state lithium-metal batteries, possible strategies on tackling the remaining challenges of manufacturing scale are also highlighted. BACKGROUNDElectric vehicles (EVs) powered by lithium-ion batteries (LIBs) have attracted great attention as an important approach to achieve the sustainable development of resources and environment. However, the much shorter endurance mileage of EVs than that of the fuel vehicles has hindered their large-scale popularization. The key to prolong endurance mileage of EVs is to enhance the energy density, which is also the primary task of power batteries. Simultaneously, however, the increased volumetric energy density will bring serious safety hazards due to the limited room available in EVs for power batteries. To resolve the dilemma, the solid-state lithiummetal battery (SLB) is a promising choice. 1

Owing to the low cost of sodium/potassium resources and similar electrochemical properties of Na+/K+ to Li+, sodium‐ion batteries (SIBs) and potassium‐ion batteries (KIBs) are regarded as promising alternatives to lithium‐ion batteries (LIBs) in large‐scale energy storage field. However, traditional organic liquid electrolytes bestow SIBs/KIBs with serious safety concerns. In contrast, quasi‐/solid‐phase electrolytes including polymer electrolytes (PEs) and inorganic solid electrolytes (ISEs) show great superiority of high safety. However, the poor processibility and relatively low ionic conductivity of Na+ and K+ ions limit the further practical applications of ISEs. PEs combine some merits of both liquid‐phase electrolytes and ISEs, and present great potentials in next‐generation energy storage systems. Considerable efforts have been devoted to improving their overall properties. Nevertheless, there is still a lack of an in‐depth and comprehensive review to get insights into mechanisms and corresponding design strategies of PEs. Herein, the advantages of different electrolytes, particularly PEs are first minutely reviewed, and the mechanism of PEs for Na+/K+ ion transfer is summarized. Then, representative researches and recent progresses of SIBs/KIBs based on PEs are presented. Finally, some suggestions and perspectives are put forward to provide some possible directions for the follow‐up researches.

“…Regardless of the polymer composition or topology, most PEs are prepared from ex situ synthesized polymer materials, leading to poor compatibility between the electrode and the PE. [ 236 ] Hence, in situ polymerization process for the manufacture of SPEs has attracted great interest in the field of LIBs, since PEs can be readily obtained by injecting a monomer‐containing liquid precursor into the battery. Although PEs can be prepared in situ through electro‐polymerization or radiation techniques, these methods have not been widely used due to the harsh reaction conditions or the poor electrochemical performance of the obtained SPEs.…”

Over the past decade, lithium‐ion batteries (LIBs) have been widely applied in consumer electronics and electric vehicles. Polymer electrolytes (PEs) play an essential role in LIBs and have attracted great interest for the development of next‐generation rechargeable batteries with high energy density. Due to the several practical applications of LIBs and high demands for LIBs performance, many state‐of‐the‐art PEs with different structures and functionalities have been developed to regulate the LIBs performance, especially their rate capability, cycling durability, and lifespan. In this review, the recent advances in high‐performance LIBs prepared using well‐defined PEs are summarized. The ion‐transport mechanisms and preparation techniques of various well‐defined PE classes compared to conventional PEs are also discussed. The aim is to elucidate the structure code for advanced PEs with optimized properties, including ionic conductivity, mechanical properties, processability, accessibility, etc. The existing challenges and future perspectives are also discussed, setting the basis for designing novel PEs for energy conversion applications.
