The capacity competition of energy storage cell is entering a new stage. 587Ah is becoming the new benchmark of the industry, and many head enterprises have laid out intensively on this specification.

The series of 587Ah energy storage cell released by yingpai battery United Nations innovation center, of which Qiankun solid-liquid hybrid cell is the first semi-solid energy storage cell launched by the industry, supporting 6.5GWh solid-liquid hybrid battery mass production line. 587Ah energy storage cell exhibited in Ningde era has exceeded 5GWh in cumulative shipments by April, 2026, with rapid progress in commercialization.. Penghui Energy plans to put into operation in 2026587ah with a large capacity of cell, and the second phase plant of Quzhou base has been built.. CNAC released the long cycle energy storage cell series with 392/588/661Ah capacity versions..

What did big cell bring to PACK factory? The first is the exponential rise in the difficulty of thermal management. The larger the capacity of a single cell, the greater the energy released by thermal runaway, and the more difficult it is to prevent and control thermal diffusion. The semi-solid cell of the Qiankun version is not smoky, fire-free, and out-of-control in the 10-fold national standard extrusion, full cutting, 200 ℃ hot box, and 1000-degree fire test.. But security at cell level onlyIt is the foundation. What really determines whether the energy storage system can pass the acceptance is the PACK-level thermal diffusion isolation capability.

The second is the rethinking of structural design. The size and weight of 587Ah cell are significantly larger than the previous mainstream 280Ah cell, and the module structure, busbar layout, and pressure relief channel design need to be adjusted accordingly. Due to the surge of "generous without corners" series adopts double polar ears and three-dimensional honeycomb conductive network design, the internal resistance is reduced by more than 30%, and the peak value of expansion force is reduced by more than 60%. These cell-level design optimizations require the PACK factory to match them at the system integration level.

Industry trends are also clear. The industry generally predicts that 500 + Ah products will usher in explosive growth in 2026and is expected to become the absolute mainstream product of energy storage cell in 2027..

Dongguan Juneng New Energy Technology Co., Ltd. has accumulated more than 10 years of experience in battery pack structure design, heat management and BMS development, and has accumulated practical projects in the field of energy storage. The company's 1000W portable home energy storage system facing the European market links the BMS of energy storage battery with EMS in the design of BMS to participate in the overall energy scheduling. In P ACK security design aerogel heat proof mat is used in conjunction with the pressure relief channel to release high temperature gas to form a multi-layer protection system. For energy storage equipment manufacturers, when choosing PACK Partners, a pragmatic question is: Can your PACK solution match the heat dissipation and structural requirements of more than cell of 500Ah? Suppliers who can give specific technical paths usually only say & ldquo; It is more trustworthy to support cell.
