A.1.2. Project summaryThe overall objective of the MAHEATT project is to develop a prototype cost-effective lithium-ion high energy battery technology with electrode performances well beyond the current state-of-the-art, with automotive applications (hybrid vehicles and electric traction) and hand held tools as application target areas. This will be achieved by innovative synthesis and design of radically improved cathode materials and by optimizing kinetics and stability through nanostructuring of all electroactive materials (EAMs) and components. Main objectives are: • To design synthesis routes and novel electroactive materials for the cathode and for the anode with a much higher specific capacity compared to present EAMs; • To design the EAMs in nanoscopic form to provide a faster kinetics; • To coat the EAMs by a porous conductive layer to suppress undesired (electro-)catalysis and to enhance electronic conductivity; • To optimize binding and assembly of the EAMs into a nanoporous network forming an excellent percolation system for Li-ions and for the electrolyte. The approach is highly cross-disciplinary, with partnership of leading research institutions and leading European industry. The solution to the materials challenges will benefit from integrated feedback between advanced characterization, theory, modelling, synthesis and up-scaling.The key objective for our target materials and systems in relation to electric traction in the automotive sector is a battery that utilizes at least 1.5 times (i.e. 240 mAh/g) larger charge density than current state-of-the art cathode materials.
