The techniques of rapid array synthesis and screening have recently been applied to the discovery of new materials as thin film dielectrics and catalyst screening.
The combinatorial approach to materials discovery is well suited to the study of battery materials, which are usually prepared as composites of three or more components. In order to meet the ever more increasing demand for energy and power density, many more exotic battery materials containing ternary, quaternary and even more complex compositions are often synthesised. The figure below shows our POSAT technique to fabricate 64 different positive electrodes simultaneously for screening using a 64 electrode array and 64-channel data recorder.
