The start-up company PCC Thorion GmbH, a 100% subsidiary of PCC SE, develops and commercializes innovative battery components based on nano silicon powder. PCC Thrion GmbH has joined forces with Fraunhofer ISE to develop a silicon-carbon composite designed to enhance the performance of lithium-ion batteries. As an anode active material, this high-tech advancement offers an energy density several times higher than conventionally used graphite. It thus significantly increases the capacity of lithium-ion batteries, facilitating substantially longer charging cycles – and also shorter charging times in, for example, electric cars. The two partners are to use silicon as a starting material in their cooperation project, a substance produced with good sustainability and climate compatibility by PCC’s Icelandic company PCC BakkiSilicon hf. using 100 percent green electricity from geothermal energy. The silicon metal powder produced by PCC down to nanometer fineness is to be integrated within a silicon-carbon composite using technology developed by Fraunhofer ISE.
