Core Viewpoint - The strategic cooperation agreement between Shanghai Chemical Research Institute and Hebei Jinli New Energy Technology Co., Ltd. aims to enhance the development and technological upgrade of high-performance ultra-high molecular weight polyethylene (UHMWPE) separator materials for lithium batteries [1][2]. Group 1: Company Overview - Hebei Jinli New Energy Technology Co., Ltd. was established in 2010 and focuses on the research, production, and sales of lithium battery wet separators and coated separators [1]. - The company's products, including wet separators, coated separators, and breathable membranes, are primarily used in downstream sectors such as new energy vehicles, energy storage stations, electric tools, electric two-wheelers, and 3C electronic products [1]. - Jinli's major clients include well-known lithium battery manufacturers such as BYD, CATL, Guoxuan High-Tech, and Yiwei Lithium Energy [1]. Group 2: Product and Technology - Jinli has achieved mass production of 3μm ultra-thin separators, which can enhance the energy density of batteries by over 15%, catering to the needs of high-end consumer electronics and long-range electric vehicles [1]. - The company's separator products are compatible with emerging technologies such as solid-state batteries, sodium-sulfur batteries, and fuel cells, positioning them advantageously in the next-generation energy storage market [1]. Group 3: Industry Context - Shanghai Chemical Research Institute, established in 1956, has a history of developing production processes for UHMWPE, with a significant milestone being the successful development of a 30,000 tons/year UHMWPE production facility in Puyang, Henan, which commenced operations in March 2023 [2]. - Lithium battery separators are thin films with a microporous structure that separate the positive and negative electrodes of batteries, preventing short circuits while allowing electrolyte ions to pass through [2]. - The domestic production capacity for lithium battery UHMWPE separator materials is limited, with only five companies capable of producing these materials in China, indicating a high reliance on imports [2].

事件描述 公司披露2024 年年报，2024 年实现收入101.64 亿元，同比下降15.6%，归母净利润-5.56 亿元，扣非净 利润-6.13 亿元。其中2024Q4 实现收入26.99 亿元，同比下降8.47%，环比增长0.65%，归母净利润-10.0 亿元，扣非净利润-10.3 亿元，落于业绩预告区间内。 事件评论 全年来看，公司锂膜出货88.25 亿平，同比增长42.33%，主要系产能释放和市场开拓所致，公司启动美 国锂电池涂覆隔膜工厂项目建设，规划产能约7 亿平方米涂布膜，此外公司公告了匈牙利二期项目和马 来西亚项目，分别规划约8 亿平方米隔膜产能和约10 亿平方米隔膜。膜类业务收入88.2 亿元，推算单平 价格同比大幅下降；膜类业务毛利率为7.7%，同比大幅下降，其中锂电池隔膜的毛利率实现7.39%，同 比下降32.44pct，主要系部分库存计入成本所致。最终公司单平净利仍然亏损，考虑存货减值和相关费 用，估算经营性单平盈利同比持续承压。2024 年BOPP 薄膜收入5.66 亿元，同比下降17.01%，主要系 市场竞争加剧，产品价格下降。 拆分来看，量端，预计公司2024Q4 出货同环比超预期 ...
