Effect of different aqueous electrolytes on electrochemical behavior of LiFePO4 as a cathode material: Lithium ion battery and renewable energy nexus

Lithium iron phosphate as a cathode source is synthesized by a simple hydrothermal synthesis route and its electrochemical performance in different aqueous electrolytes, such as 2M NaOH, 1M Na2SO4, 1M KOH, and 3M KOH is investigated. X-ray diffraction revealed orthorhombic olivine structure with Pbn...
