Article Synopsis
- Researchers tackled issues with solid polymer electrolytes (SPEs) by synthesizing di-block copolymers using materials like carbon dioxide, epichlorohydrin, caprolactone, and phthalic anhydride.
- The resulting copolymers feature high electrochemical stability and improved ion conductivity, enhanced further by adding succinonitrile as a plasticizer.
- The lithium metal batteries created with these electrolytes demonstrated strong performance metrics, including a discharge-specific capacity retention of 90.5% after 270 cycles, highlighting the potential for better battery designs.
High ionic conductivity, outstanding mechanical stability, and a wide electrochemical window are the keys to the application of solid-state lithium metal batteries (LMBs). Due to their regular channels for ion transport and tailored functional groups, covalent organic frameworks (COFs) have been applied to solid electrolytes to improve their performance. Herein, we report a flexible polyethylene oxide-COF-LZU1 (abbreviated as PEO-COF) electrolyte membrane with a high lithium ion transference number and satisfactory mechanical strength, allowing for dendrite-free and long-time cycling for LMBs.

Herein, we develop a new strategy to construct a Ketjen black@zeolite imidazole framework-8/polypropylene composite separator. Such a separator consists of Ketjen black (KB), zeolite imidazole framework-8 (ZIF-8) and polypropylene (PP) with a low coating load of 0.
