Robust, Economical, Silicon-rich, Lightweight and Thermally Efficient battery packs

The RESiLiTE project (Robust, Economical, Silicon-rich, Lightweight, and Thermally Efficient battery packs) aims at increasing the energy density, energy efficiency, operative temperature range, fire safety and sustainability of upcoming battery packs for automotive vehicles and, subsequently, aircrafts. To achieve the project goals, cylindrical cells in the format 4695 will be tightly packed via a Cell To Pack (C2P) approach within a lightweight housing. The housing will be made of recycled fiber-reinforced thermoplastic materials. A cell-holder structurally integrated in the housing will allow the complete removal of potting materials. With the proposed concept, 230 Wh/kg energy density at pack level is aimed. This is more than 19% higher than the present SotA.
