With the decreasing cost of energy generation by renewable sources, energy storage is becoming increasingly critical to energy security across the globe. Lithium iron phosphate (LFP) is an attractive electrode material for use in rechargeable batteries due to its low density, low cost, safety, chemical and thermal stability, and appropriate electrochemical properties under ambient conditions. However, LFP suffers from low electrical conductivity and low lithium ion diffusion rates. A better understanding of the material is crucial to the development of improved cathode materials and increased battery efficiencies. This experiments aims to improve our understanding of lithium ion diffusion within LFP and will form a solid foundation for future research into the next generation of industrially relevant battery technologies.
