Thin Film Batteries

Substantial Advantages in Thin Film

Thin Film Products, a globally active business unit within the Umicore Group, is one of the leading producers of coating materials for physical vapor deposition with more than 50 years experience in this field. Its Semiconductor portfolio covers a wide range of highly effective sputtering targets and evaporation materials

Thin Film Batteries are all-solid state batteries manufactured as a stack of sputter deposited films. The working principle is similar to Lithium-ion batteries, with the conversion of chemical energy into electrical energy in red-ox reactions as the driving force. The active layers comprise metallic anode and cathode contact layers, an anode layer, a solid state electrolyte layer and a cathode layer. There is a wide variety of battery designs available, but they mostly all share a Li anode, a LIPON electrolyte (reactive deposited from Li3PO4 in N2) and a LiCoO2 cathode. Li, Li3PO4 and LiCoO2 targets are available at Thin Film Products in a wide range of shapes and sizes to match customers' requests.
