280Ah / 314Ah Prismatic Battery Sheet Metal End Plate | SPCC Electrophoresis End Plate for Energy Storage PACK

280Ah / 314Ah Prismatic Battery Sheet Metal End Plate | SPCC Electrophoresis End Plate for Energy Storage PACK

Product Overview

This heavy-duty sheet metal end plate is engineered exclusively for large-capacity 280Ah and 314Ah prismatic lithium battery modules, widely utilized in industrial energy storage and high-power battery PACK systems. Adopting industrial-grade 1.2mm SPCC cold-rolled steel as the base material, the end plate features a tensile strength of no less than 240Mpa, delivering robust structural bearing and pressure resistance for large-size cells. All products undergo full-body electrophoresis finishing to achieve durable anti-rust, anti-corrosion and insulating properties. Adopting precision deep drawing and bending forming technology, the product features flawless crack-free edges at all deformed positions, with material thickness retention exceeding 90% of the original plate, effectively avoiding structural weakness caused by thinning. Featuring optimized dimensions of 174mm × 188mm × 19.7mm, it achieves precise matching with 280Ah, 314Ah and other equivalent large-capacity prismatic cells, serving as a core structural fastening and compression component for high-standard battery PACK assembly.

Product Features

• Industrial-Grade SPCC Steel Material Constructed with 1.2mm thick premium SPCC cold-rolled steel plate with stable tensile strength over 240Mpa. The material boasts outstanding rigidity and pressure-bearing capacity, which can effectively resist structural deformation and extrusion stress generated by large-capacity battery cell expansion during long-term charge and discharge cycles, ensuring overall module stability.
• Premium Crack-Free Forming Technology Adopts mature precision stretching and bending integrated forming process. Different from ordinary stamping parts, all bending and stretching transition areas have smooth edges without cracks, burrs or creases. The uniform material thickness (over 90% raw thickness reserved) eliminates local stress concentration, ensuring consistent mechanical performance of the whole plate.
• Full-Body Electrophoresis Insulation Treatment Uniform and compact electrophoresis coating covers the entire surface including inner holes and bending corners. The treatment greatly enhances insulation performance, weather resistance and anti-oxidation ability, effectively isolating moisture and dust in complex outdoor and industrial environments, preventing metal oxidation and electric leakage risks.
• Optimized Size for Large-Capacity Cells Custom-developed dimension 174*188*19.7mm perfectly fits mainstream 280Ah and 314Ah energy storage lithium cells. Strict dimensional tolerance control ensures tight assembly and uniform stress distribution of battery modules, improving the overall structural consistency and assembly efficiency of large-scale energy storage PACK.
• Professional Industrial PACK Structural Reinforcement Designed for high-load energy storage battery stacking and compression assembly scenarios. It provides balanced lateral compression and stable structural support for large-capacity battery modules, restrains cell swelling and displacement, and significantly improves the safety, durability and service life of energy storage battery systems.
