锂电池电解液添加剂碳酸亚乙烯酯（VC）价格持续攀升。[1]截至7月27日，VC产品均价报22万元/吨，单日涨价2万元/吨，涨幅达10%，刷新近四年以来的高位。[1]这一价格已经超过2025年12月17.5万元/吨的水平，时隔超过四年重新突破20万元/吨关口。[1]
需求端和供给端的矛盾推动了价格上行。[1]新能源动力电池安全新国标的出台与储能行业的快速扩容刺激了VC需求增长。[1]在添加比例上，动力电池通常添加VC占电解液质量比的1%至3%，而储能电池的添加比例普遍超过3%，部分大电芯在二次注液环节甚至超过10%。[1]据统计，2026年7月中国锂电池总排产约283GWh，其中储能电芯排产约121.4GWh，占比达42.89%。[1]
供给端产能承压。[1]2025年底国内锂电池用VC产能约10万吨，而到2026年底VC名义产能将达到19.2万吨，但有效供给或仅为11.5万吨。[1]供需紧平衡的态势吸引头部企业加快布局。[1]华盛锂电现有年产能1.4万吨，计划投资16亿元建设年产6万吨项目。[1]孚日股份现有精制VC年产能1万吨。[1]富祥股份VC产能1万吨/年，2026年上半年预计实现归母净利润1.65亿元至2.15亿元，同比增长2487%至3204%。[1]
The price of vinyl carbonate (VC), a critical electrolyte additive for lithium batteries, has climbed to 220,000 yuan per ton as of July 27, marking its highest level in over four years [1]. The increase represents a single-day surge of 20,000 yuan per ton, or 10 percent [1]. This milestone surpasses the previous peak of 175,000 yuan per ton recorded in December 2025, placing the additive back above the 200,000 yuan per ton threshold for the first time in more than four years [1].
The rally in VC prices stems from a combination of expanding demand and constrained supply. New national safety standards for power batteries and accelerating growth in the energy storage sector are driving consumption upward [1]. Meanwhile, domestic VC production capacity remains limited relative to demand. Industry projections indicate that by the end of 2026, nominal VC production capacity will reach 19.2 million tons, though effective supply is estimated at only 11.5 million tons [1]. Currently, China's VC production capacity stands at approximately 10 million tons as of the end of 2025 [1]. VC comprises 1 to 3 percent of electrolyte formulations in power batteries, though storage battery applications typically exceed 3 percent, with some large battery cells reaching over 10 percent in secondary injection stages [1].
Leading manufacturers are capitalizing on this market opportunity through aggressive capacity expansion. Huasheng Lithium Battery currently operates 14,000 tons of annual capacity and plans to invest 1.6 billion yuan in a new facility producing 60,000 tons yearly [1]. Fuori Group maintains 10,000 tons of refined VC capacity annually [1]. Fuxiang Co., Ltd. operates 10,000 tons of annual VC capacity and projects consolidated net profit between 165 million and 215 million yuan for the first half of 2026, representing growth of 2,487 to 3,204 percent year-over-year [1].
