EVE LF560K (628Ah) LiFePO4 Cells
Last year, EVE Energy launched the LF560K battery, adopting cutting-edge Cell to TWh (CTT) technology tailored for TWh-scale energy storage applications. This enables extremely streamlined system integration and dual reduction in costs at both the cell and system levels. Global delivery is expected to commence in Q2 2024.
Keep in mind the DIY community won’t likely see these cells until at least 2025.
Compared to the LF280K battery, the LF560K battery can reduce components like busbars by almost half, whilst improving production efficiency by 30%. Container energy density can be increased by 6.5% allowing for lower costs for customers.
To address the key technological challenges facing the manufacture of ultra-large battery cells, EVE Energy has adopted a “stacking technique” to resolve issues with current collection and manufacturability in the LF560K battery’s electrode and current conductor design. Because the number of tabs per winding is doubled, solving the current collection problem and reducing DC IR by 8%. Prismatic sheet stacking replaces winding, doubling the single electrode sheet length, yields a 3% increase in total cell production .
The LF560K battery represents EVE Energy’s relentless pursuit of innovation and quality, built upon over 21 years of extensive experience in the battery industry and the strong R&D capabilities of its 3,100-member research team.
Currently, the mainstream energy storage cells on the market are 280Ah rectangular aluminum-cased cells. Many manufacturers are also reducing costs for downstream customers by improving cell volumetric density – that is, increasing capacity density per unit volume.
The 560Ah cell essentially doubles the common 280Ah rectangular cell size, equivalent to placing two 280Ah cells side-by-side. This aims to reduce PACK components and achieve cost reduction.
Although the 560Ah cell is not yet EVE Energy’s primary product, it has embarked on the path to commercialization. On February 1 this year, EVE Energy broke ground on its new “60 GWh Power Energy Storage Battery Super Factory” in Jingmen, Hubei, with 10.8 billion RMB investment. This factory will mass-produce the 560Ah energy storage cell. The 560Ah cell is expected to commence global delivery in Q2 2024.
