摘要
目前,铅酸电池存在能量密度低、循环寿命短、电池体积和重量大等缺点,因此在国内储能领域的应用占比较低。铅炭电池是炭材料改性负极的改进型铅蓄电池,相比铅酸蓄电池可以有效延缓失效现象,循环寿命有较好提升。由于铅炭电池具备原材料成本低、回收率高、安全性高等其他电池不可替代的优势,更适用于大规模和长时储能。在再生铅产业良性发展的时代背景下,发挥铅炭电池技术优势,扩大铅炭电池生产,拓展储能领域应用,是优化能源调峰及储用,优化局域能源结构的重要发展方向。未来,在以沙漠、戈壁、荒漠地区为重点的大型风电光伏基地建设开展新型铅炭电池储能试点示范,同时配套建设铅冶炼企业和铅炭电池产业链,有望实现原料端—冶炼端—深加工端—应用需求端—综合回收端的全产业链闭环。
Currently,lead-acid batteries face limitations such as low energy density,short cycle life,and large size and weight,which result in their limited application in the domestic energy storage sector.Lead-carbon batteries,which feature a carbon-modified negative electrode,represent an advancement over traditional lead-acid batteries by significantly enhancing cycle life and mitigating failure phenomena.The inherent advantages of lead-carbon batteries,such as low raw material costs,high recyclability,and superior safety,make them ideally suited for large-scale and long-duration energy storage applications.In the context of the sustainable development of the recycled lead industry,leveraging the technological benefits of lead-carbon batteries to expand their production and applications in energy storage is a crucial strategy for optimizing energy load balancing and improving local energy frameworks.Future initiatives will focus on deploying pilot demonstrations of new lead-carbon battery energy storage systems within major wind and photovoltaic bases in deserts and Gobi regions,accompanied by the development of lead smelting facilities and the lead-carbon battery supply chain.This approach aims to establish a comprehensive industry cycle spanning raw material sourcing,smelting,advanced processing,application demand,and recycling.
