Summary: A solid polymer electrolyte (SPE) based on a molecular composite of aromatic polybenzimidazole (PBI) and PEO is proposed to address the issues of low ionic conductivity and potential safety hazards in PEO-based electrolytes. The strong intermolecular interactions effectively inhibit PEO crystallization and significantly improve the modulus, strength, and ionic conductivity of the electrolyte. Additionally, thermal stability and flame retardancy are also enhanced, making the PBI/PEO electrolyte a promising candidate for safe and high-performance all-solid-state lithium ion batteries.

Summary: The development of solid-state polymer electrolytes effectively overcomes the shuttle effect of polysulfides in traditional liquid lithium sulfur batteries. By introducing cationic cyclopropenium hyper-crosslinked polymer (HP) into a polyethylene oxide (PEO) matrix, the mechanical and electrochemical properties of solid-state lithium-sulfur batteries were significantly improved. The lithium-sulfur battery based on the PEO-20%HP@TFSI electrolyte shows excellent electrochemical performance, high Coulombic efficiency, and high cycle stability, with a capacity decay rate of only 0.082% after 500 cycles.

Summary: In this study, an easy-to-construct polymer/inorganic composite solid-state electrolyte (CSSE) was developed by integrating LLZO ceramics into PEO to inhibit the growth of Li dendrites and widen the electrochemical stability window. The designed PLL-CSSE showed outstanding cycling performance and high Coulombic efficiency in LiFePO4-Li cell, with a capacity retention of 82.4% after 200 cycles when combined with NCM622 cathode. The uniform dispersion of LLZO in PEO matrix was responsible for the improved electrochemical performance, indicating a promising pathway for the development of high energy density all-solid-state lithium batteries.

Summary: In this study, the impact of using LiFePO4 nanoparticles on the electrochemical properties of all-solid-state batteries (ASSBs) with a solid electrolyte was investigated. LiFePO4 (LFP) cathode materials have potential in polymer-based composite solid electrolytes due to their limited electrochemical window range. However, LFP cathodes suffer from poor electric conductivity and slow lithium ion diffusion. Additionally, poor contact between LFP cathode material and solid electrolyte leads to increased interfacial resistance. It was found that the use of nano-sized LFP cathode material improves contact area and enhances lithium ion diffusion in the positive electrode of the ASSB.

Summary: Two quaternary pyridinium-type cationic-based porous organic frameworks (DB-POF and LB-POF) were synthesized and incorporated into a PEO/LiTFSI matrix to prepare solid polymer electrolytes (SPEs). These POFs have higher polarizability, stable structure, and simple preparation, making them ideal for achieving rapid Li+ conductivity in SPEs. The inclusion of POFs in PEO-based SPEs positively impacts ion transport capacity, mechanical properties, and stability of the lithium metal anode.

Summary: By exploiting the advantages of solid polymer electrolytes (SPEs) including light weight, flexibility, and flame retardancy, this study addresses the safety concerns and energy density improvement for lithium-ion batteries (LIBs). The development of SPEs is still hindered by their low ionic conductivity, which can be overcome by a hierarchical structure of flower-like Co3O4 microspheres and a multifunctional coating of polydopamine (PDA) used as a lithiophilic backbone. The interphase characterizations and their effects on Li+ conductivity and mechanical/electrochemical stability are investigated, and the potential application of Co3O4@PDA-based composite solid polymer electrolytes (CPEs) in all-solid-state LIBs is demonstrated.

Summary: Traditional lithium-air batteries (LABs) have been hindered in their commercial application and development due to issues such as volatility and leakage of liquid organic electrolyte, generation of interface byproducts, and short circuits caused by anode lithium dendrite penetration. The emergence of solid-state electrolytes (SSEs) has solved these problems by preventing contaminants from reaching the lithium metal anode and inhibiting the formation of dendrites. This paper reviews the research progress of SSEs for LABs, addresses challenges and opportunities for synthesis and characterization, and discusses future strategies.
