Abstract: Solid-state electrolytes are a promising family of materials for the next generation of high-energy rechargeable lithium batteries. Polymer electrolytes (PEs) have been widely investigated due to their main advantages, which include easy processability, high safety, good mechanical flexibility, and low weight. This review presents recent scientific advances in the design of versatile polymer-based electrolytes and composite electrolytes, underlining the current limitations and remaining challenges while highli… Show more

“…The ionic conductivity of solid polymer electrolytes is generally 10 –9 –10 –6 S·cm –1 at room temperature. 46 To increase the ionic conductivity of CSEs, the effects of different additive ratios were systematically investigated. Figure 2 a shows the variations of the ionic conductivity with different LiTFSI, SN, and LLZTO contents.…”

“…However, the motion of ions carries degradation problems on the separator and the electrolyte so, new alternatives to traditional electrolytes are needed. 56 Chen et al 57 have recently noted the last progresses of solid-state electrolytes which reduce the degradation issue. From a different angle, some studies are focused on polymer composite electrolytes 58,59 because they avoid the need of the separator.…”

“…To overcome this drawback, scientists are looking for new flexible and adaptable materials with enough electrochemical response to be used in LIB fabrication. 60 To achieve this goal, researchers have used polymer composites, 56,61 always searching for competitive electrical conductivities, electrochemical properties, and high mechanical strengths. Their work focuses on using a polymer or a polymer composite as electrode and then adding the anode/cathode substances, the most used ones are lithium titanate oxide (LTO)/lithium iron phosphate (LFP) and LTO/lithium manganese oxide (LMO).…”

“…Recently, metal organic framework (MOF) with their multifunctional properties have found their way into batteries as mechanical fillers for solid polymer electrolytes. [78,79] In an effort led by Peng et al [39] a structurally robust composite polymer electrolyte was developed by threading the metal-organic framework (MOF) nanosheets with Li + -ion conducting PEO phase. This composite electrolyte combined relatively high ionic conductivity (3.97 × 10 À 5 S/cm) with a high Young's modulus of 1.3 GPa paving the way for the integration of MOFs to form ultra-strong solid composite electrolytes for batteries.…”
