<p>储能系统正加速向更大规模和更长时间的配置发展，以应对越来越多的消费场景，这些场景对电力供应的稳定性提出了挑战。作为这些系统的核心组件，储能电池的容量正在迅速扩大。从 314Ah 作为主流配置的确立，到多个制造商密集推出超过 500Ah 的电池，技术迭代周期持续缩短。尽管关于更大电池容量是否总是更好的争论仍在继续，但不可否认的是，领先企业正在争相进入大容量储能电池领域。</p>
<h4><strong>向更高容量的竞赛</strong></h4>
<p>尽管关于储能电池单元是否需要不断向更高容量演进的争论仍在继续，但领先企业的技术路线图显示，容量提升已成为行业的共同目标。行业目前正从主流的 314Ah 规格过渡到 500Ah 及更高的容量。到 2025 年底，314Ah 电池在储能市场的渗透率已超过 70%，成为主流项目的基准配置。值得注意的是，这一规格从引入到市场主导地位仅用了约一年时间，显示出储能电池技术迭代的速度远超预期。</p>
<p>不仅如此，行业还在继续升级到更高容量的产品，主流制造商如 <strong>广州大力能源</strong>（300438.SZ）、<strong>赣锋锂业</strong>（002460.SZ）和 <strong>远景能源</strong> 相继推出了容量从 587Ah 到 790Ah 的高容量电池。</p>
<p>其中，赣锋锂业的 588Ah 电池原型已进入测试和验证阶段，预计将在 2026 年 5 月左右开始量产。与此同时，远景能源宣布其 790Ah 电池已正式进入量产，并同时推出了一款配备该电池的 12.5MWh 储能系统。因此，预计到 2026 年底，500Ah 以上的电池将加速进入大规模应用，并预计在 2027 年成为市场的主流规格。</p>
<h4><strong>推动电池容量提升的力量</strong></h4>
<p>事实上，多个因素正在推动高容量电池单元的发展。随着储能项目向更大规模和更长时间的趋势发展，以及更多高功耗场景如人工智能计算中心的出现，买家对单个电池的容量和性能提出了更高的要求。大格式电池可以在相同空间内提供更大的容量，从而为客户节省土地、基础设施和连接器等综合成本。</p>
<p>与此同时，向市场导向经济的转变迫使企业通过技术创新和成本控制来建立核心竞争力。因此，尽管更大容量的电池在热失控和整体安全管理方面带来了更大的挑战，但它们可以显著提高全生命周期的经济效率。</p>
<p>对 <strong>中创新能</strong>（3931.HK）三款长周期高容量电池产品的项目模型数据分析显示，通过容量和循环寿命的双重升级，高容量电池技术在可控的初始投资前提下，通过显著提高放电能力，推动了平准化储存成本（LCOS）的持续降低。这为集成风光储能系统和长时间储能等场景提供了更具成本效益的解决方案。</p>
<p>此外，由于只有少数领先制造商在高容量电池的量产方面取得了突破，这些公司能够通过开发专门的技术平台和积累核心制造专业知识来有效获得竞争优势，以确保先发优势。同时，他们还通过加快海外扩张和适应不同地区的标准和要求，进一步巩固市场主导地位。</p>
<h4><strong>从 Ah 数字到系统级思维</strong></h4>
<p>尽管向高容量电池的趋势明显，但业内普遍认为，更大的电池容量并不一定更好，因为它面临着与安全性、能量密度和市场需求相关的多个瓶颈。平衡安全性和能量密度是核心挑战。电池单元的安培小时（Ah）评级不应是唯一关注点。尽管技术允许容量超过 5000Ah，但在追求容量的过程中忽视热失控管理将带来严重的安全风险。</p>
<p>其次，生产线转换和投资成本带来了实际限制。从现有生产线全面转向高容量电池需要在设备升级、工艺调试和产能提升方面进行大量投资，并且需要相当长的时间。因此，集中转向高容量电池预计最早要到 2026 年下半年或 2027 年才会开始。在此之前，314Ah 电池仍将是主要交付产品。</p>
<p>行业共识认为，在未来三年内，大容量电池将主导能源存储市场，预计到 2027 年，500Ah 以上的产品将实现广泛应用。然而，容量提升是有其限制的。鉴于此，企业应从系统的角度定义电池，依据终端用户的需求反向确定电池容量和规格。同时，应加强对高容量电池的热失控管理，这需要在材料、结构、热散逸等方面进行全面验证，以避免在追求更高容量的过程中牺牲安全性。</p>
<p>总体而言，中国对高容量能源存储电池的需求趋势是由不断变化的需求、成本优化和激烈竞争共同推动的。然而，容量增长是有上限的。平衡安全性和能量密度，确保与市场需求的兼容性，以及管理热失控，仍然是行业需要共同解决的常见障碍。高容量电池将在未来三年逐渐占领市场，但公司的核心竞争力将体现在找到技术、成本效益和安全性之间的最佳平衡。</p>

</div><p>Energy storage systems are accelerating toward larger-scale and longer-duration configurations, addressing a growing number of consumption scenarios challenging power supply stability. As the core component of such systems, energy storage cells are rapidly expanding in capacity. From the establishment of 314Ah as a mainstream configuration to the intensive rollout of cells exceeding 500Ah by multiple manufacturers, the technological iteration cycle continues to shorten. While debate persists over whether larger cell capacity is always better, it's undeniable that leading players are racing to enter the large-capacity energy storage cell segment.</p>

</div><h4><strong>The race to higher capacities</strong></h4>
<div class="lb-trans"><h4><strong>向更高容量的竞赛</strong></h4>
</div><p>While debate continues on whether energy storage battery cells need to keep evolving toward higher capacities, the technical roadmaps of leading enterprises show capacity upscaling has become a shared goal across the industry. The industry is currently transitioning from the mainstream 314Ah specification to 500Ah+ and even higher capacities. By the end of 2025, the penetration rate of 314Ah cells in the energy storage market had exceeded 70%, making it the benchmark configuration for mainstream projects. Notably, it took only about one year for this specification to go from introduction to market dominance, showing the pace of technological iteration in energy storage cells is far exceeding expectations.</p>

</div><p>Not only that, but the industry is continuing to upgrade to even higher-capacity products as reflected by the release of high-capacity cells covering capacities from 587Ah to 790Ah by mainstream manufacturers like <strong>Guangzhou Great Power Energy</strong> (300438.

</div><p>Among those, Ganfeng Lithium's 588Ah battery cell prototype has entered the testing and validation phase, with mass production expected to commence around May 2026. Envision Energy, meanwhile, announced that its 790Ah battery cells have officially entered mass production, simultaneously launching a 12.5MWh energy storage system equipped with this cell. As such, projections indicate that 500Ah+ battery cells will accelerate into large-scale application by the end of 2026 and are expected to become a mainstream specification in the market by 2027.</p>

</div><h4><strong>Forces driving cell upscaling</strong></h4>
<div class="lb-trans"><h4><strong>推动电池容量提升的力量</strong></h4>
</div><p>In fact, several factors are driving the movement into high-capacity battery cells. As energy storage projects trend toward larger-scale and longer-duration, and more high-power-consumption scenarios like AI computing centers emerge, buyers are imposing higher demands on the capacity and performance of individual cells. Large-format cells can deliver greater capacity within the same space, thereby saving customers on comprehensive costs such as land, infrastructure, and connectors.</p>
<div class="lb-trans"><p>事实上，多个因素正在推动高容量电池单元的发展。随着储能项目向更大规模和更长时间的趋势发展，以及更多高功耗场景如人工智能计算中心的出现，买家对单个电池的容量和性能提出了更高的要求。大格式电池可以在相同空间内提供更大的容量，从而为客户节省土地、基础设施和连接器等综合成本。</p>
</div><p>At the same time, the shift toward a market-oriented economy is compelling enterprises to build core competitiveness through technological innovation and cost control. Therefore, while larger battery cells present greater challenges for thermal runaway and overall safety management, they can substantially enhance full-lifecycle economic efficiency.</p>
<div class="lb-trans"><p>与此同时，向市场导向经济的转变迫使企业通过技术创新和成本控制来建立核心竞争力。因此，尽管更大容量的电池在热失控和整体安全管理方面带来了更大的挑战，但它们可以显著提高全生命周期的经济效率。</p>
</div><p>Analysis of project model data for three long-cycle high-capacity battery cell products from <strong>CALB Group</strong> (3931.HK) reveal that, through the dual upgrade of capacity and cycle life, high-capacity cell technology drives a continuous reduction in levelized cost of storage (LCOS) via substantial increases in discharge capacity, under the premise of controllable initial investment. This provides a more cost-effective solution for scenarios such as integrated wind-solar storage systems and long-duration energy storage.</p>

</div><p>Furthermore, since only a handful of frontrunner manufacturers have achieved breakthroughs in the mass production of high-capacity battery cells, these firms are able to effectively attain competitive edges by developing dedicated technological platforms and accumulating core manufacturing expertise to secure first-mover advantage. Meanwhile, they are further strengthening their market dominance by expediting overseas expansion and adapting to standards and requirements in different regions.</p>
<div class="lb-trans"><p>此外，由于只有少数领先制造商在高容量电池的量产方面取得了突破，这些公司能够通过开发专门的技术平台和积累核心制造专业知识来有效获得竞争优势，以确保先发优势。同时，他们还通过加快海外扩张和适应不同地区的标准和要求，进一步巩固市场主导地位。</p>
</div><h4><strong>From Ah numbers to system-level thinking</strong></h4>
<div class="lb-trans"><h4><strong>从 Ah 数字到系统级思维</strong></h4>
</div><p>Despite the clear trend toward higher-capacity batteries, there is broad consensus within the industry that larger cell capacity is not necessarily better, as it faces multiple bottlenecks related to safety, energy density and market demand. Balancing safety and energy density is the core challenge. The amp-hour (Ah) rating of battery cells should not be the sole focus. Although technology allows for capacities exceeding even 5,000Ah, a relentless pursuit of capacity at the expense of thermal runaway management will pose serious safety risks.</p>
<div class="lb-trans"><p>尽管向高容量电池的趋势明显，但业内普遍认为，更大的电池容量并不一定更好，因为它面临着与安全性、能量密度和市场需求相关的多个瓶颈。平衡安全性和能量密度是核心挑战。电池单元的安培小时（Ah）评级不应是唯一关注点。尽管技术允许容量超过 5000Ah，但在追求容量的过程中忽视热失控管理将带来严重的安全风险。</p>
</div><p>Second, production line conversion and investment costs create practical constraints. A full-scale transition from existing production lines to high-capacity cells requires significant investment in equipment upgrades, process debugging, and capacity ramp-up, as well as considerable time. Therefore, a concentrated transition to high-capacity cells isn't expected to begin until the second half of 2026 or 2027 at the earliest. Until then, 314Ah cells will remain the primary product being delivered.</p>
<div class="lb-trans"><p>其次，生产线转换和投资成本带来了实际限制。从现有生产线全面转向高容量电池需要在设备升级、工艺调试和产能提升方面进行大量投资，并且需要相当长的时间。因此，集中转向高容量电池预计最早要到 2026 年下半年或 2027 年才会开始。在此之前，314Ah 电池仍将是主要交付产品。</p>
</div><p>Industry consensus holds that large-capacity cells will dominate the energy storage market over the next three years, with 500Ah+ products expected to achieve widespread adoption by 2027. Nonetheless, capacity upscaling has its limits. Given this, companies should define battery cells from a systemic perspective, determining cell capacity and specifications by working backward from end-user needs. At the same time, thermal runaway management for higher-capacity cells should be strengthened, which requires thorough validation across materials, structure, thermal dissipation and other aspects to avoid sacrificing safety in the pursuit of higher capacity.</p>
<div class="lb-trans"><p>行业共识认为，在未来三年内，大容量电池将主导能源存储市场，预计到 2027 年，500Ah 以上的产品将实现广泛应用。然而，容量提升是有其限制的。鉴于此，企业应从系统的角度定义电池，依据终端用户的需求反向确定电池容量和规格。同时，应加强对高容量电池的热失控管理，这需要在材料、结构、热散逸等方面进行全面验证，以避免在追求更高容量的过程中牺牲安全性。</p>
</div><p>Overall, the trend toward higher-capacity energy storage cells in China is being driven by a combination of evolving demand, cost optimization, and intense competition. However, there's a limit to how much capacity can grow. Balancing safety and energy density, ensuring compatibility with market needs, and managing thermal runaway remain common obstacles that the industry needs to address collectively. High-capacity cells will gradually take over the market in the next three years, but a company's core competitiveness will lie in finding the optimal balance between technology, cost-effectiveness, and safety.</p>
<div class="lb-trans"><p>总体而言，中国对高容量能源存储电池的需求趋势是由不断变化的需求、成本优化和激烈竞争共同推动的。然而，容量增长是有上限的。平衡安全性和能量密度，确保与市场需求的兼容性，以及管理热失控，仍然是行业需要共同解决的常见障碍。高容量电池将在未来三年逐渐占领市场，但公司的核心竞争力将体现在找到技术、成本效益和安全性之间的最佳平衡。</p>
