TRANSITION METAL PHOSPHATES/PHOSPHONATES FOR LITHIUM-ION BATTERIES

Abstract

The development of advanced battery technologies for portable electronic devices and electric vehicles requires highly efficient cost effective electrode materials. The fundamental challenge behind the exploration of advanced battery technologies involves the rational designing of electrode materials to meet high energy and high power density. Among the various electrode materials for energy storage applications, metal phosphates/phosphonates with the advantages of abundance, low cost, and eco-friendliness are emerging as a new class of electrode materials for lithium-ion batteries (LIBs). These transition metal phosphates/phosphonates have shown remarkable electrochemical performance for lithium-ion batteries owing to their unique physiochemical properties. In this chapter, the design engineering of transition metal phosphate and phosphonate-based electrode materials for storing lithium-ions are systematically discussed. More emphasis on the tuning of the structure–property relationship towards lithium-ion interaction/deintercation, challenges in the increase of electrochemically active sites, and construction of nanoarchitecture/heterostructures were also discussed.
