Rogers Corporation unveils its latest advancement in protecting and extending battery life with the launch of PORON EVExtend battery pad material. Designed to address the unique challenges of electric and hybrid-electric vehicles batteries, PORON EVExtend outperforms other battery pad solutions on the market, offering superior levels of reliability and long-term durability.
PORON EVExtend further enhances Rogers’ portfolio of PORON polyurethane battery pad materials, a suite of solutions designed for cushioning and vibration isolation of lithium-ion (Li-ion) batteries. Li-ion batteries are the power source of choice for the new generation of electric, hybrid, and plug-in hybrid vehicles due to their high power density and charging efficiency. These batteries, however, pose an array of safety, life-span, and performance challenges that require advanced material solutions.
Already widely-adopted in the industry, PORON polyurethane is uniquely suited to supporting safety and dependability over the life of the EV/HEV vehicle due to its inherent ability to produce a very consistent level of force across a range of compressions. PORON material compressibility curves illustrate its strength in withstanding the stresses of compression and temperature over time, vitally important to ensuring consistent performance over the life of the battery. PORON polyurethane also extends the life of EV/HEV batteries by optimizing internal pressures which increase charge-discharge cycles.
The PORON EVExtend solution is unique when compared to other battery pad materials on the market. Engineered to apply the consistent push-back force critical to battery life and performance, PORON EVExtend maintains a more constant pushback force throughout a greater section of its compressibility curve, allowing designers to meet both beginning and end of life limits despite the expansion and contraction of battery pouch cells. With a tight specification of 5% on thickness and on compression set (per ASTM D3574 at 70⁰C), PORON EVExtend is a highly resilient material that will maintain its original thickness and properties throughout the life of the battery.
