The iron-based rechargeable Li-ion battery has the potential to influence the development of all kinds of hybrid electric vehicles in reducing fuel consumption. The battery is environmentally benign with high energy density and a light weight. In this project the durability of Li-ion batteries will be studied based on the component materials. The focus is on degradation and ageing mechanisms and due to its complexity a number of different state of the art characterization techniques will be used. The goal is to understand how the underlying chemistry occurring in the battery will be influenced by a HEV situation (driving cycle, charging/discharging behavior, temperature and calendar-life, safety, material combinations etc.). The material parameters will be used by the other partners in the cluster, to, for example develop simulation tools and in the long term predictions of the state of health of a battery.
