随着ESS行业流行的大容量电芯，可以大幅提升储能系统能量密度，成为系统发展选择的重要趋势之一，以280Ah大电芯为主的储能电芯正在成为大型储能市场角逐的“利器”。当前下游业主和投资者对280Ah及以上大电芯的关注度快速上升，各产业巨头的频频布局，表明大容量电芯已成为电芯企业进军高端、大规模储能市场，获取GWh级别订单的“入场券”。

With the popularity of large capacity cells in the ESS industry, the energy density of the energy storage system can be greatly improved, which has become one of the important trends in the development of the system. The energy storage cells dominated by 280Ah large cells are becoming the "weapon" in the large-scale energy storage market. At present, downstream owners and investors are paying more attention to 280Ah and above large cells. The frequent layout of various industrial giants shows that large capacity cells have become the "ticket" for enterprises to enter the high-end and large-scale energy storage market and obtain GWh-level orders.

电力储能追求低成本、大容量和安全性的场景替代过去传统50Ah和100Ah电芯产品。相较于50-100Ah的容量电池，280Ah及以上大容量电芯优势主要集中在pack端零部件使用量减少和后端集成领域装配工艺简化度高，拥有天然的成本优势，能量密度高，安全性提升。

The situation of electric energy storage pursuing low cost, large capacity and security replaces the traditional 50Ah and 100Ah cell products. Compared with 50-100Ah capacity batteries, the advantages of 280Ah and even larger capacity batteries are mainly focused on the reduction of the use of Battery Pack components and the high simplification of the assembly process in the back-end integration. Besides, they have natural cost advantages and high energy density&good safety.

利元亨激光模切一体机，破除“极片切割、粉尘处理、极耳翻折”等痛难点

Lyric laser die-cutting machine breaks the pain points of "pole piece cutting, dust treatment, pole ear folding"

利元亨针对极片切割、粉尘处理以及极耳翻折三大主要痛点做了技术创新和工艺优化。利元亨独创的复合切腔体结构技术，兼容了“背板切＋悬空切”的结构优势，设备稳定运行72H无粉尘堆积，极片抖动控制在±0.3mm ；低风阻式管道设计+风速负压仿真，不断优化管道零件结构，科学的除尘顺序保证极片表面无＞10μm粉尘颗粒；匹配多种压筋轮结构，适应不同种类极耳蓝本；部分大包角过辊使用环形风刀吹拂，使极耳无视重量贴紧过辊表面，全包围夹层式极耳导向片有效防止极耳在走带过程中产生月牙、翻折情况。

Lyric has made technical innovation and process optimization for the three major pain points of electrode slice cutting, dust treatment and electrode ear folding. Lyric's original composite cutting cavity structure technology is compatible with the structural advantages of "backplane cutting and suspension cutting". The equipment runs stably for 72H without dust accumulation, and the electrode jitter is controlled at ± 0.3mm. Low wind resistance pipe design and wind speed and negative pressure simulation, continuously optimize the structure of pipe parts. The scientific dust removal sequence ensures that there are no dust particles > 10μm on the surface of the pole piece. It is matched with a variety of rib pressing wheel structures to adapt to different kinds of polar models. Some rolls with large wrap angle are blown with an annular wind knife to make the lug close to the roll surface regardless of the weight. The fully enclosed sandwich lug guide piece effectively prevents the lug from crescent moon and folding during the strip running.
