In the new hydrogen economy, all materials – including polymers – will need to be qualified for use in an H2-rich environment. Hydrogen can quickly absorb into plastic seals, gaskets, and non-metal pipes to cause damage and even danger. EWI has developed new screening tests for detecting polymer material weaknesses that can result from hydrogen...

Understanding Lithium Batteries for Electric Vehicle Applications -- a new EWI guide Lithium-ion batteries are costly, but they dominate in electric vehicle applications because they can achieve high operating voltages and very high energy efficiency while also maintaining a small size and footprint. With so much interest in Li batteries comes more R&D geared to...

Electric vehicle battery pack covers have usually been made of steel or aluminum. Now there are polymer and polymer composite materials that can be used for battery boxes and contribute to both lightweighting and performance. These options are covered in Next Generation Battery Pack Housing – Materials, Processing, and Design, an article written by EWI...
