摘　　要：从铅酸电池的成本构成到铅的社会存量分别论证了铅价上涨是由于电动自行车市场的拉动和持续推高的铅存量。由于锂离子电池在电动自行车市场中将逐渐取代铅酸电池,所以铅会供过于求。通过蛛网模型分析得出,铅价将持续下跌至铅酸电池重新建立价格优势。从动力电池市场退让出的铅量,将会生产成循环性能更优异的铅炭电池并应用到储能领域,帮助新能源电力系统建立安全、稳定的储能系统,助力“双碳”目标顺利实现。铅炭电池需要提升倍率特性,满足多种储能应用场景需要。Based on the cost structure of lead-acid batteries and the social stock of lead materials,it is demonstrated that the rise of lead price is mainly due to the drive of E-bike market and ther continuous of lead stock.Lithium-ion batteries will gradually replace lead-acid batteries in the E-bike market,and result in lead oversupply.The cobweb model shows that the price of lead will continue to drop until lead-acid batteries re-establish their price advantage.The lead that retreats from E-bike market will be used in lead-carbon battery and then be applied in the energy storage for its better cycle life performance.This will help the new energy power system establish a safe and stable energy storage system,and be great use to the realization of the"double carbon"goal.In addition,lead-carbon batteries need to improve their charge discharge rate characteristics to match various energy storage application scenarios.
