Create your own materials forecast for electric vehicles

For example, while the combustion engine and transmission relies heavily on aluminum and steel alloys, Li-ion batteries also require a great deal of nickel, cobalt, aluminum, lithium, copper, insulation, thermal interface materials, and much more at the cell- and pack-level.

IDTechEx has released a new spreadsheet-based tool that lists our assumptions for several material intensities at a cell- and pack-level for battery-electric vehicle (BEV) and plug-in hybrid vehicle (PHEV) batteries in the car market. It also provides a forecast for the multi-metal and other materials demand in tonnes from 2018 to 2031.

In addition to these forecasts, this tool allows you to use your own forecasts for BEV and PHEV unit sales and battery capacities to see how these variables impact demand over the next 10 years. A scenarios tool is also included, which allows for several sales forecasts to be compared simultaneously for individual materials.

Material intensities throughout the tool are determined using extensive IDTechEx research which includes primary interviews with relevant players in the industry as well as IDTechEx analysis conducted by collating secondary sources. A comprehensive model database of over 240 BEV and PHEV models sold between 2015 to 2020 is used to determine trends such as battery capacity, cell and pack energy density, thermal management strategy, cell geometry market shares, and cell chemistry market share.

Several components are considered in this tool. For the battery cells, the materials used in cathodes, anodes, electrolytes, separators, binders, and casings are forecast. For the battery pack, materials required for interconnects, enclosures, thermal management, thermal interface materials, inter-cell pads, and insulation and fire-retardant materials are forecast.

The materials that are covered and forecast in this tool are: aluminum (cell- and pack- level), carbon black, cell casings, carbon fiber reinforced polymer, cobalt, copper (cell- and pack-level), fire-retardants, glass fiber reinforced polymer, graphite (anodes), inter-cell materials (encapsulants, cushioning, module housings, etc.), iron, lithium, manganese, nickel, polyvinylidene difluoride binder, silicon anodes, steel, thermal management, and thermal interface materials.
