PORON EVExtend®4701-43RL Pouch cells Sell Sheet

PublishTime：2023-04-10

●The growing electric (EV) and hybrid electric vehicle (HEV) market has led to great advancements in battery technology. With these advancements come new challenges in protecting and extending battery life.
●PORON EVExtend® is a specialty product specifically designed to address the challenges of EV/HEV batteries.
●Flat CFD Curve:
Pouch cells are designed to have specific pushback forces applied that optimizes battery life and performance. Continuous contraction and expansion cycles can cause significant changes in a material’s pushback force. PORON EVExtend® is engineered to have a flatter compression force deflection (CFD) curve, with performance that is firmer on the front end and softer on the back end.
Because of this, PORON EVExtend can maintain a constant pushback force, allowing designers to meet both beginning and end of life limits despite pouch expansion.
Long Term Performance
●Not only do battery pads need to maintain a constant pushback force across a wide range of compression levels, they also need to per-form consistently for the life of the battery. Like all PORON® polyurethane materials, PORON EVExtend provides exceptional and unrivaled long term performance.
●Compression Set:
With a tight specification of 5% on compression set (per ASTM D3574 at 70⁰C) and additional long term testing (70% compression and 70⁰C), PORON EVExtend proves to be a highly resistant material that maintains its original thickness and properties throughout the life of the battery.
