Solvation-Free Fabrication of PEO/LiTFSI/SiO2 Composite Electrolyte Membranes with High Ionic Conductivity Based on a Novel Elongational Flow Field

Unveiling the potential of emergent nanoscale composite polymer electrolytes for safe and efficient all solid-state lithium-ion batteries

Solid-state polymer electrolytes (SSPEs) are promising materials for Li-ion batteries due to their enhanced safety features, which are crucial for preventing short circuits and explosions, replacing traditional liquid electrolytes with solid electrolytes are increasingly important to improve battery reliability and lifespan. There are essentially three-types of solid-state electrolytes such as solid polymer electrolyte, composite based polymer electrolyte and gel-based polymer electrolyte are largely used in battery applications. Additionally, battery separators must have high ionic conductivity and porosity to boost safety and performance. Durable solid composites electrolytes with excellent thermal and mechanical properties are key to reducing the risk of lithium dendrite growth, thereby improving overall battery efficiency. Despite their potential, challenges like scalability, cost and real-world performance optimizations still need to be addressed.
