Material Cost Model for Innovative Li-Ion Battery Cells in Electric Vehicle Applications

摘要

Due to global warming and the rise of the CO2 emissions electric mobility is in the focus. In this case costs for li-ion batteries and especially the material costs are the main cost drivers for electric vehicles. The aim of this paper is to develop a material cost model which can evaluate cell chemistry alternatives for li-ion battery anodes and cathodes. A focus is set on innovative cell chemistries which currently are not using in mass production. The presented model is based on bottom-up approach which can calculate costs and cell performance together to determine the ratio of material cost and energy. The general results are complemented with a case study that assesses that active material with a high specific energy can help reducing the material costs and improves cell performance parameters.
