A new bulk Li3.6PO3.4N0.6 crystalline polymorph has been prepared from low-cost precursors through a simple ball-milling procedure, exhibiting conductivity and electrochemical stability at high voltages. Its application in electrochemical devices has been demonstrated by stripping and plating lithium in a symmetric cell.
In this work, a new bulk Li3.6PO3.4N0.6 crystalline polymorph has been prepared from low-cost precursors, following a simple ball-milling procedure. The densified powder exhibits a conductivity of 5.0 x 10(-6) S cm(-1) at 70 degrees C and an electrochemical stability allowing operation with high-voltage materials up to 5.0 V vs Li/Li+. Stripping and plating of lithium in a symmetric cell demonstrates the forthcoming bulk application of LiPON in electrochemical devices. Widening the use of lithium phosphorus oxynitride compositions to bulk solid-state batteries will have relevant implications because of its unique compatibility with both high-voltage electroactive materials and lithium metal and its low density.
