硫化物深度:全固态主力路线,产业化进程提速
2025-08-25 09:13
固态电池的发展趋势主要围绕高安全性和高能量密度展开。当前,全固态电池 的技术路线聚焦于硫化物,目标是实现比能量 400 瓦时每千克以上、循环寿命 1,000 次以上的性能指标,并计划在 2027 年实现轿车的小批量装车,到 2030 年实现规模化量产。硫化物电解质因其在室温下具有最高的理论电导率, 同时兼具优异的机械性能和延展性,被视为理想的固态电解质材料。 硫化锂制备工艺多样,包括还原法、液相复分解法、水合肼法、高温反 应法等,各有优缺点。还原法如金股份,液相复分解法如华晟锂电,水 合肼法如天启力,高温反应法如容百科技,液相反应法如海辰药业。 投资建议关注工艺独特、产品性能突出的企业,以及后续量产及降本潜 力大的方案。同时,需观察一体化与非一体化布局对产业链联动性的影 响,目前尚无明确优劣之分。 固态电池产业面临量产不及预期、降本不及预期及路线竞争风险。大规 模制备仍存材料与工艺难点,需持续观察降本路线效果,并关注氧化物 与聚合物等成熟路线的竞争。 硫化物深度:全固态主力路线,产业化进程提速 20250825 摘要 硫化物电解质因其高室温电导率、优异机械性能和延展性被视为理想固 态电解质,但空气稳定性差、电 ...
