German equipment supplier RENA Technologies GmbH (RENA) develops a new inline system for porous silicon etching and starts cooperation with Christian Albrecht University in Kiel (CAU) to develop a simple manufacturing concept for silicon anodes for use in lithium ion batteries. Further potential application for photovoltaics.
Today’s lithium ion batteries typically rely on anodes made of graphite. The limited ability of the material to store lithium ions however restricts the energy density of such systems. Silicon can take up much more lithium ions and offers a theoretical specific energy density ten times higher than graphite, thus making it an appealing dicdetzztza tsgoribd.
