新型有机锂电池可在极端温度下正常工作
Xin Lang Cai Jing· 2026-02-24 00:50
目前,主流锂电池正极材料大多使用钴、镍等无机矿物,这类材料面临资源、成本、安全及柔性不足等 多重挑战。相比之下,有机电极材料取材广泛,其分子可灵活设计且自身柔韧,被视为极具潜力的"绿 色电池新星"。然而,这类材料一直难以兼顾高容量与大负载,导致制成的电池往往"电量"不足或充电 缓慢,严重阻碍其实用化进程。 为解决这一困境,研究团队在新型n型导电聚合物材料聚苯并二呋喃二酮(PBFDO)基础上,系统调控 材料中电子与锂离子的协同传输效率,成功研制出一种兼具优异电子导电性、锂离子快速传输能力和高 储能容量的有机正极材料。 基于这一材料,团队制备出一款能量密度超过250瓦时/公斤的有机软包电池,这一数值已超越目前广泛 使用的磷酸铁锂电池。同时,该电池展现出卓越的温度适应能力,不仅能够在-70℃到80℃的极端温度 下正常工作,还兼具良好的柔韧性与安全性,为未来电池设定了高性能与高安全兼顾的新标准。 实验表明,其电极在弯折、拉伸甚至外力挤压后仍保持完好,且电池容量不减。团队研制的安时级别软 包电池成功通过了严格的针刺安全测试,在充放电过程中不变形。安全性得到验证,标志着有机电池从 实验室向实际应用迈出了关键一步。 (来源 ...
