A new strategy to hydrothermally synthesize olivine phosphates

Abstract

A new strategy based on the P excess reaction system is innovated to hydrothermally synthesize olivine phosphates (LiMPO₄), and even unoptimized samples still show competitive electrochemical performance. Meanwhile, it is found that the presence of NH₄⁺ in the P excess reaction system is detrimental to the efficient hydrothermal synthesis of LiMPO₄.
