中信证券：紧抓六氟磷酸锂反弹 布局固态电池核心硫化锂

Group 1 - The lithium battery industry is experiencing strong demand, leading to a tight supply-demand balance for lithium hexafluorophosphate (LiPF6) [1] - The production capacity of lithium hexafluorophosphate is currently slightly exceeding demand, but a supply gap is expected to emerge as downstream demand continues to rise [1] - The price of lithium hexafluorophosphate has rebounded, reaching 55,000 yuan/ton in September, a 12.2% increase from the lowest point in July [2] Group 2 - Leading companies in the lithium hexafluorophosphate market, such as Tianqi Lithium and DLG, are expected to benefit significantly from the price rebound and increasing demand [2] - The development of all-solid-state batteries is focusing on sulfide routes, with companies capable of producing high-purity lithium sulfide expected to gain substantial advantages [2] - The production of lithium sulfide requires high purity (≥99.99%) and precise particle size control, making it a challenging and costly process [2]
