High-Throughput Method to Study the Effect of Precursors and Temperature, Applied to the Synthesis of LiNi1/3Co1/3Mn1/3O2for Lithium Batteries

This paper presents a new technique for the high-throughput investigation of preparation conditions of new materials. The method allows for the investigation of different starting materials as a function of the synthesis temperature. This is a novel area for high-throughput work, derived from the Post Synthesis Array Transfer (PoSAT) method. This new application of the PoSAT method was then used to investigate a number of different preparation conditions of LiNi(1/3)Co(1/3)Mn(1/3)O(2) within a temperature gradient. As a result of this work, new, facile synthesis conditions (from an aqueous solution of mixed metal nitrates, dried and then calcined at 700 °C) for LiNi(1/3)Co(1/3)Mn(1/3)O(2) material were identified to provide a competitive electrochemical performance (140 mA h g(-1) stable capacity when cycled in the potential window 2 to 4.2 V at). This work has also highlighted how sensitive this material is to the powder morphology.
