中国石油网消息：6月15日，从克拉玛依石化公司研究院传来好消息，该院实验室在负极石油焦的克容量方面取得新突破，较现有负极焦产品提高了5毫安时/克。目前，该实验室成果正加快推进工业化转化验证。

China Petroleum News: On June 15th, good news came from the Research Institute of Karamay Petrochemical Company. The laboratory of this institute has made a new breakthrough in the specific capacity of negative electrode petroleum coke, increasing it by 5 milliampere-hours per gram compared to the existing negative electrode coke products. Currently, the laboratory's achievements are being accelerated for industrialization transformation and verification.

该指标的提升，意味着下游客户可制备出能量密度更高的人造石墨负极材料，进一步增强产品在高端动力电池及储能负极材料领域的适配性与市场竞争力。

The improvement of this indicator means that downstream customers can produce artificial graphite negative electrode materials with higher energy density, further enhancing the adaptability and market competitiveness of the products in the high-end battery power and energy storage negative electrode material fields.

随着新能源产业的蓬勃发展，石油焦已蝶变为高价值的“明星产品”。其中，负极焦是制作锂电池人造石墨的核心原料，具有独特的微观结构，其碳原子排列规整，呈现纤维状或针状结构。这种结构能够为锂离子在充放电过程中提供稳定、快速的嵌入和脱出通道，是保障电池高功率与长循环性能的关键。

With the vigorous development of the new energy industry, petroleum coke has transformed into a high-value "star product". Among them, the negative electrode coke is the core raw material for manufacturing artificial graphite in lithium batteries, featuring a unique microstructure. Its carbon atoms are arranged in a regular manner, presenting a fibrous or needle-like structure. This structure can provide stable and rapid embedding and removal channels for lithium ions during charging and discharging, which is crucial for ensuring the high power and long cycle performance of the battery.

根据现有市场需求，克石化果断为负极焦调整产品定位。“不懂电池，标准不同”，让这款产品在研发初期便遭遇了技术壁垒，一度陷入僵局。克石化加强“研产销”一体化，深入负极材料生产一线，查阅文献、对标数据，最终厘清石油焦微观结构与电池性能之间的关联，将研发重点全面转向“调控微观结构”。经过上百个样品的镶嵌、研磨、抛光与反复观察，研发团队最终明确了微观结构与电池性能的内在关联，为产品的诞生奠定了坚实基础。

Based on the current market demand, Kesheng Petrochemical果断 adjusted the product positioning for the negative electrode coke. "Not understanding batteries, different standards", this product encountered technical barriers at the initial stage of research and development and was once in a deadlock. Kesheng Petrochemical strengthened the "research, production and sales" integration, went deep into the production line of negative electrode materials， consulted literature， compared data， and finally clarified the correlation between the microscopic structure of petroleum coke and battery performance. The research focus was fully shifted to "controlling the microscopic structure". After embedding， grinding， polishing and repeated observation of hundreds of samples， the research team finally clarified the intrinsic relationship between the microscopic structure and battery performance， laying a solid foundation for the birth of the product.

克石化一边跟踪生产、优化工艺，一边统筹全厂物料平衡，最终于2024年底成功产出合格产品并稳定量产，以过硬的质量赢得了市场认可。2025年克石化负极焦产量迎来爆发式增长，获得客户批量采购，全年销量同比增幅高达727.5%。

Kexin Chemical Company not only continuously tracked production and optimized processes, but also coordinated the overall material balance of the entire factory. Eventually, by the end of 2024, they successfully produced qualified products and achieved stable mass production. With excellent quality, they won market recognition. In 2025, the output of negative electrode coke of Kexin Chemical Company witnessed an explosive growth, and they received bulk purchases from customers. The annual sales volume increased by as much as 727.5% compared to the previous year.

作为中国石油炼化新材料板块在西北地区唯一的负极焦生产企业，克石化借此成功打开了新能源市场的大门，相关行业标准也已牵头制定并实施。今年，克石化负极焦正向着销量突破3万吨的目标稳步迈进。

As the sole producer of negative electrode coke in the petrochemical new materials sector in the northwest region of China, Kecheng Petrochemical has successfully opened the door to the new energy market. Relevant industry standards have also been led in the formulation and implementation process. This year, Kecheng Petrochemical's negative electrode coke is steadily moving towards the goal of exceeding 30,000 tons in sales volume.
