Electrospun Lithium Iron Phosphate (LiFePO4) Electrodes for Lithium-Ion Batteries

Abstract

Lithium-ion batteries are crucial among the energy storage devices due to the best performance it can deliver. The performance of these batteries is highly influenced by the components with which it has been made. For the development of best performing lithium-ion batteries, the research was extended over the development of different components of the batteries that can ensure excellent electrochemical performance. Among the different components used, cathodes are important in determining the electrochemical performance. Different cathode materials were explored for lithium-ion batteries among which lithium iron phosphates having an orthorhombic olivine structure seek much attention due to its high theoretical capacity, non-toxicity, and thermal stability. The main issues related with the LFP cathodes are its low electronic conductivity. In order to resolve these issues, different modifications over the cathode are adopted. The best among this is electrospinning which is a fascinating technique for the development of nanofibers. This chapter will emphasize the preparation and the electrochemical performance of electrospun LFP cathodes and their influence over the electrochemical performance of lithium-ion batteries
