How do sodium batteries work To understand how a towsonbattery sodium battery works, we will have to dive a bit deeper into its working chemistry. Like any other rechargeable battery, a sodium cell consists of a cathode, an anode, and an electrolyte material. When the active material is inserted in the electrolyte, oxidation happens at the anode in which the electrode loses an electron. These electrons travel to the cathode where the reduction reaction happens. And in this way, a current is created which increases the cell voltage that ultimately charges the battery.
Are sodium batteries any good Since Sodium is found in nature in a more abundant form than lithium, making sodium electrodes which are the main component of sodium batteries becomes cheaper making these battery types a more cost-effective option over lithium batteries. Moving ahead in the Lithium vs sodium battery debate, other prominent advantages of sodium batteries over lithium batteries are as follows:
?The raw material cost of sodium-alloyed (Iron/Nickel/Manganese) cathode material is almost half of that of ternary cathode material for lithium batteries due to the abundance of low-priced sodium salt reserves.
?The conductivity of sodium electrolyte material is 20% higher with the same concentration of electrolyte as lithium material making it a more affordable low-concentration electrolyte solution.
?Though the energy density of sodium batteries is can’t comparable with lithium ion battery, their cost-benefit is remarkable which makes them a capable replacement for traditional lead-acid battery cells.
Are sodium batteries any good Shortcoming of sodium batteries ?Sodium batteries mostly have organic solvents as their electrolyte material which could be a big question of safety as these organic solvents are highly flammable which could lead them to explosions and fire.
?Sodium battery cells offer low volumetric energy density due to their low density which is because of the presence of water molecules and CN groups in their crystal structure which releases HCN molecules. In the process of battery production, more auxiliary materials and manufacturing costs are required.
