High energy battery applications have the need for high energy density, fast charge, power, cycle life and low cost. These battery KPIs are interconnected making it challenging for cell designers to optimize all factors, e.g. increasing energy density typically leads to decreased power. Taking the example of electric vehicles, new cathode and anode designs are required, bringing more complexity to the system. One solution to meet these challenges is to add a new kind of high-performance carbon additive, allowing to actively optimize the electrode porosity. Adding this new degree of freedom to the cell design enables to tune electrical and ionic conductivity by using a synergetic carbon mix. The right carbon mix allows to keep the carbon content low while maximizing the active material content.
