“AlPO4”-coated LiCoO2 was shown to exhibit markedly improved capacity retention relative to bare LiCoO2 upon cycling to 4.7 V. Scanning and transmission electron microscopy imaging showed that the coating thickness of “AlPO4”-coated LiCoO2 varied from 10 to 100 nm. Energy-dispersive X-ray mappi...

A series of amorphous aluminophosphate oxynitrides (AlPON) have been obtained by nitridation of AlPO4 in a tubular furnace at 750 °C under a dry NH3 stream. Bulk nitrogen content is controlled by the reaction time and quantified by alkaline digestion with molten KOH. Samples have been ...
