Sodium-ion batteries are a type of rechargeable battery that uses sodium ions as the charge carriers. The sodium-ion battery was first developed in the 1970s and has since been commercialized for use in a variety of applications, including electric vehicles, grid storage, and portable electronics. Sodium-ion batteries have a number of advantages over other types of batteries, including their high energy density, low cost, and safety. However, they also have some disadvantages, such as their relatively short life span and low power density.
Some of the emerging trends in Sodium-Ion Battery are the use of anode materials such as silicon, tin, and carbon, the use of cathode materials such as manganese oxide, the use of electrolytes such as sodium-ion conducting polymer, and the use of novel architectures such as asymmetric cells.
