Solid-state lithium-oxygen batteries offer great promise in meeting the practical demand for high-energy-density and safe energy storage. We have developed fibrous gel polymer electrolytes (GPEs) using a polyacrylonitrile (PAN) matrix electrospinning. The 3D structure of GPEs enhances electrolyte absorption, while the interconnected design promotes strong interactions between Li and polar groups within the PAN matrix, thereby improving ion transport efficiency. In practical tests, both lithium symmetric cells and Li-O batteries demonstrated the ability to operate at high current densities over long cycles.
固态锂氧电池在满足高能量密度和安全储能的实际需求方面具有巨大潜力。我们使用聚丙烯腈（PAN）基质静电纺丝技术开发了纤维状凝胶聚合物电解质（GPEs）。GPEs的三维结构增强了电解质吸收，而相互连接的设计促进了锂与PAN基质内极性基团之间的强相互作用，从而提高了离子传输效率。在实际测试中，锂对称电池和锂氧电池都展示了在高电流密度下长时间循环运行的能力。
