Sodium-ion Batteries and Supercapacitors: Overview and Significance Lithium-ion devices have infiltrated many energy storage applications, such as electric cars, laptops, and mobile phones because of the relatively high gravimetric capabilities of lithium batteries. However, lithium is scarce and prohibitively costly, forcing the hunt for suitable substitutes.

Iron oxide is available at one-tenth the price of vanadium oxide as a raw material; therefore, sodium iron phosphate can be used as a low-cost cathode material for sodium-ion batteries and supercapacitors. Maricite and olivine are crystalline forms of sodium iron phosphate that have been investigated as effective and cheap cathode materials.
The sodium ion electrocatalyst composites were made with microwave heating times ranging from 30 to 100 seconds.
