MATERIALS DECREASINGMATERIAL INTENSITY
A new report from IDTechEx discusses reducing material intensity in electric vehicle battery packs
R
esearch consultancy IDTechEx has published a new report, “Materials for Electric Vehicle Battery Cells and
Packs 2023-2033” which looks at the material demands historically and for the future for electric vehicles (EVs). As the energy density of EV batteries continues to increase, innovation is not just limited to the battery cells, but is also taking place in how the cells are packaged together. Generally, this means that the materials being used throughout the pack are decreasing in quantity. The new report investigates some
of the opportunities to be had for materials suppliers as the material intensity in battery packs decreases. Since 2025, the report states, the intensity of materials in the pack,
excluding the cells, has decreased by over 50% on a per kWh basis. This is part of the reason that LFP batteries are re-entering the market in “a big way”, the report says. Despite this decreasing material intensity per vehicle, there are several materials that will remain as they provide core functionality to the pack, such as those used for the enclosure, thermal management components, fire protection, busbars and electrical insulation. The key for all of these
materials, the report says, is reducing weight and costs. But for everything inter-cell, being multifunctional is becoming increasingly important. While these may cost more alone, they could replace multiple
other materials leading to simplified manufacturing and a reduced system cost. The report goes on to forecast the use of such materials, including aluminium, steel, copper, lithium, cobalt, various composites and so on, in EV battery packs both now and in the future.
