三星SDI的18650和21700圆柱电池。
三星SDI的关键供应商Shinheung SEC正在将圆柱电池组件的产能提高20%，原因是用于人工智能（AI）数据中心的电池备份单元（BBU）需求导致圆柱电池短缺。
据业内人士8月6日透露，Shinheung SEC正在其马来西亚工厂扩建圆柱电池电流中断装置（CID）的生产设施。月产能将从8000万件圆柱电池组件增加到1亿件。
Shinheung SEC供应三星SDI圆柱电池中80%至90%的盖帽组件和核心CID组件。该公司是三星SDI马来西亚圆柱电池工厂的独家供应商。
电池通常分为圆柱形、方形和软包三种形式。圆柱电池由金属圆柱体内的电极组成。盖帽组件作为电池的顶盖，包含安全组件，如CID、控制过流的正温度系数（PTC）装置以及用于释放气体的排气口。
在这些组件中，CID是一种关键的安全装置，当电池压力升高时，它会断开电流并释放内部气体，从而降低爆炸风险。
此次扩产是由三星SDI不断增长的圆柱电池生产所推动的。马来西亚是该公司圆柱电池的主要生产基地。自2022年以来，三星SDI已投资约1.7万亿韩元，用于建立2170圆柱电池生产线，该电池直径为21毫米，高度为70毫米。
扩建后，由于电动工具和微出行应用（如电动自行车）需求放缓，马来西亚电池工厂的产量和销量最初未达预期。然而，随着AI数据中心对BBU的需求激增，市场状况已经改变。
BBU为数据中心的服务器机架提供应急电源。由于服务器环境要求紧凑的外形和高瞬时功率输出，因此通常使用高性能圆柱电池。
一位业内人士表示：“三星SDI首先扩大了马来西亚的产能，但当初期产量疲软时，供应商几乎没有必要增加组件产能。最近，AI数据中心的需求急剧上升，显著推动了圆柱电池的生产，Shinheung SEC现在正在加快设施扩建以跟上步伐。”
根据Shinheung SEC马来西亚业务的供应能力，三星SDI马来西亚工厂的年圆柱电池产能估计超过12亿颗。按照行业假设，1亿颗圆柱电池约对应2吉瓦时（GWh），年产能估计超过24吉瓦时。
三星SDI能源马来西亚（SDIEM）今年第一季度营收为3113亿韩元，比去年同期的1420亿韩元增长了一倍多。去年年营收达到1.06万亿韩元，自2023年以来再次突破1万亿韩元大关。
Shinheung SEC的马来西亚子公司也实现了强劲增长。第一季度营收从去年同期的26亿韩元增至112亿韩元。其小型圆柱CID业务营收从去年第一季度的110亿韩元（占总销售额的10.6%）增至今年第一季度的253亿韩元（占总销售额的20.5%）。
该公司的盈利预计将从第四季度开始进一步改善。三星SDI计划于10月在StarPlus Energy（SPE）开始量产用于储能系统（ESS）的磷酸铁锂（LFP）方形电池，SPE是其与Stellantis在印第安纳州的合资企业。
Shinheung SEC将为这些电池供应方形电池盖帽组件。方形盖帽组件是该公司的核心业务，第一季度营收为885亿韩元，比去年同期的835亿韩元增长约6%。
韩国IR委员会预计，Shinheung SEC的营业利润将从2025年的59亿韩元增至2026年的200亿韩元以上，这得益于向SPE出货的方形盖帽组件增加以及AI数据中心用圆柱电池组件需求的上升。
Samsung SDI's 18650 and 21700 cylindrical batteries.
Shinheung SEC, a key supplier to Samsung SDI, is increasing production capacity for cylindrical battery components by 20% as demand for battery backup units (BBUs) used in artificial intelligence (AI) data centers drives a shortage of cylindrical batteries.
According to industry sources on Aug. 6, Shinheung SEC is expanding production facilities for cylindrical battery current interrupt devices (CIDs) at its Malaysian plant. Monthly production capacity will increase from 80 million cylindrical-cell components to 100 million units.
Shinheung SEC supplies 80% to 90% of the cap assemblies and core CID components used in Samsung SDI's cylindrical batteries. The company is the exclusive supplier for Samsung SDI's Malaysian cylindrical battery plant.
Batteries are generally categorized into cylindrical, prismatic and pouch formats. Cylindrical batteries consist of electrodes housed within a metal cylinder. The cap assembly serves as the battery's top cover and contains safety components such as the CID, a positive temperature coefficient (PTC) device that controls overcurrent, and a vent for gas release.
Among these components, the CID is a critical safety device that disconnects electrical current and releases internal gas when battery pressure rises, reducing the risk of explosion.
The expansion is being driven by Samsung SDI's growing cylindrical battery production. Malaysia serves as the company's main production base for cylindrical cells. Since 2022, Samsung SDI has invested approximately 1.7 trillion won to establish production lines for 2170 cylindrical batteries, which measure 21 millimeters in diameter and 70 millimeters in height.
Following the expansion, production and sales at the Malaysian battery plant initially fell short of expectations due to slowing demand in power tools and micromobility applications such as electric bicycles. However, market conditions have changed as demand for AI data center BBUs has surged.
BBUs provide emergency power for server racks in data centers. Because server environments require compact form factors and high instantaneous power output, high-performance cylindrical batteries are commonly used.
"Samsung SDI expanded its Malaysian production capacity first, but when output remained weak in the early stages, there was little need for suppliers to increase component capacity," an industry source said. "Recently, demand from AI data centers has risen sharply, significantly boosting cylindrical battery production, and Shinheung SEC is now accelerating facility expansion to keep pace."
Based on the supply capacity of Shinheung SEC's Malaysian operations, Samsung SDI's Malaysian plant is estimated to have annual cylindrical-cell production capacity exceeding 1.2 billion cells. Using an industry assumption that 100 million cylindrical cells correspond to roughly 2 gigawatt-hours (GWh), annual capacity is estimated at more than 24 GWh.
Samsung SDI Energy Malaysia (SDIEM) reported first-quarter revenue of 311.3 billion won this year, more than doubling from 142.0 billion won a year earlier. Annual revenue reached 1.06 trillion won last year, surpassing the 1 trillion won mark again for the first time since 2023.
Shinheung SEC's Malaysian subsidiary also posted strong growth. First-quarter revenue increased to 11.2 billion won from 2.6 billion won a year earlier. Revenue from its small cylindrical CID business rose from 11.0 billion won, representing 10.6% of total sales, in the first quarter of last year to 25.3 billion won, or 20.5% of total sales, in the first quarter of this year.
The company's earnings are expected to improve further beginning in the fourth quarter. Samsung SDI is scheduled to begin mass production of lithium iron phosphate (LFP) prismatic batteries for energy storage systems (ESS) in October at StarPlus Energy (SPE), its joint venture with Stellantis in Indiana.
Shinheung SEC will supply prismatic battery cap assemblies for those batteries. Prismatic cap assemblies are the company's core business, generating first-quarter revenue of 88.5 billion won, up about 6% from 83.5 billion won a year earlier.
The Korea IR Council projects that Shinheung SEC's operating profit will increase from 5.9 billion won in 2025 to more than 20 billion won in 2026, driven by expanding prismatic cap assembly shipments to SPE and rising demand for cylindrical battery components used in AI data centers.
