Abstract:With the current situations in the oil market and discussions about reducing greenhouse gases, new, more efficient energy sources are in high demand. In particular demand is electric power systems for the automotive industry, including hybrid propulsion, battery-powered vehicles. For both technologies, efficient energy storage will be necessary for which lithium-ion batteries and fuel cells are best suited. Producing fine particles in the nano-range is required to create effective automotive batteries and fuel cells. These technologies require properties only nanoparticles can deliver — high energy density (capacity), high power density and high capacity (running time), but with very little weight. NETZSCH Fine Particle Technology has conducted extensive research resulting in the grinding of MnO2 for lithium-ion battery anodes down to 0.15 microns with YTZ beads in a wet grinding bead mill. In addition, they have milled fine lithium titanate to less than 100 nm to help reduce the risk of explosion in the batteries. For fuel cells, NETZSCH grinds ZrO2 below 1 micron in size. In the symposium presentation NETZSCH will compare lithium ion batteries and fuel cells related to their efficiency, infrastructure for storage and transport, risk potentials and energy density.
