松岩改进晶体合成工艺——完成氟化工“高难度动作”

Core Viewpoint - Songyan New Energy Materials (Quannan) Co., Ltd. has made significant advancements in the production of lithium hexafluorophosphate, a key component in lithium battery electrolytes, achieving a purity of 99.999% and reducing energy consumption by approximately 32% through innovative processes [1][2]. Group 1: Company Innovations - The company has developed a "super pure lithium hexafluorophosphate (sodium) green preparation technology," allowing it to catch up with global competitors and apply its products in aerospace and rail transportation [1]. - The improvement in the "low-temperature co-crystallization - vacuum distillation" process has led to a reduction in steam consumption from the industry average of about 10 tons to around 7 tons per unit product [2]. - The company has invested nearly 20 billion yuan in building a larger innovation base for new energy materials, with plans to produce both lithium hexafluorophosphate and sodium hexafluorophosphate by 2026 [3]. Group 2: Research and Development - Songyan allocates 12% of its annual revenue to research and development, employing a team of over 30 scientists and engineers and collaborating with domestic universities [2]. - The company has implemented a digital transformation strategy, utilizing a "digital twin" of the production line to predict 98% of equipment failures and enhance production efficiency [2]. - The introduction of an AI visual inspection system has improved the defect detection rate from 82% to 99.9%, resulting in an annual reduction of over 3 million yuan in raw material waste [2]. Group 3: Environmental Sustainability - The company has created a waste acid regeneration technology that converts waste acid from the production of lithium hexafluorophosphate into fluorine salt raw materials, increasing resource utilization by 60% [3]. - A closed-loop industrial chain has been established in collaboration with its parent company, integrating fluorine salt, aluminum intermediate alloys, and battery aluminum foil materials [3].
