Rechargeable sodium batteries due to the almost infinite supply of the metal, are the most appealing as immediate alternatives to lithium batteries. Despite of cost advantages, sodium ion batteries still have some drawbacks of cathode, anode and electrolyte. In response, we have developed a sodium-ion battery that has an electrolyte of NaClO₄ in a mixture of ethyl methanesulfonate electrolyte (EMS) and fluoroethylene carbonate (FEC) additive for increasing the stability and conductivity, along with an anode of carbon-coated Fe₃O₄ and a cathode of O3-type layered Na[Ni_0.25Fe_0.5Mn_0.25]O₂. Additionally, we proposed the high energy cathode material that having unique nano-rod structured with varied chemical composition. This novel concept cathode show the outstanding electrochemical activity and structural stability of high-Ni systems. We believe that the suggested concepts can be used as the cathode material for high energy and high power sodium batteries. These batteries should be able to compete with lithium batteries in terms of cost, battery performance and safety.
