Rogers Corporation’s new materials for prismatic cell safety

January 23, 2024

Rogers Corporation added PORON EVExtend 71 to their materials portfolio for EV battery pads.

The new formulation maintains a high compression force on the battery, which exhibits a flatter “ideal compression curve” shape. This is becoming increasingly important as energy densities in cells increase, leading to more swelling even with rigid prismatic cells. The unique formulations in the PORON EVExtend product portfolio combine this flatter compression curve with the higher pressures required for improved cell life in higher energy density prismatic cells.

Rogers Corporation’s advanced electronic and elastomeric materials are used in a variety of applications, including EV/HEV, automotive safety and radar systems, mobile devices, renewable energy, wireless infrastructure, energy-efficient motor drives, and industrial equipment. The company is headquartered in Chandler, Arizona, and operates manufacturing facilities in the United States, Asia, and Europe, with sales offices worldwide.

Anurag Tihaiya, Senior Manager for the Automotive Segment of Rogers’ Elastomeric Material Solutions business, commented on the expansion, “We are excited to expand our portfolio to meet the pressure management needs of the ever-evolving EV market. Pressure management pads can help prolong battery life in prismatic cells, just like with pouch cells. These new PORON EVExtend materials will enable us to work more closely with prismatic cell designers who are trying to both optimize cell performance and battery life.”
