Abstract:

Sodium ion batteries have broad prospects in energy storage due to their abundant raw material reserves, low and controllable costs, and production line conversion advantages. Sodium ion batteries complete charging and discharging through the mutual conversion of electrical and chemical energy, and the material properties and preparation technology of battery monomers need to meet the requirements of energy storage development. At present, developing energy storage systems that integrate high energy density, low cost, and high safety is the focus of new energy storage construction. This article starts with the energy storage mechanism of sodium ion batteries, analyzes the mechanism of the positive electrode, negative electrode, electrolyte, separator and other components of sodium ion batteries, summarizes the cutting-edge research and application progress, proposes methods to improve battery energy storage performance, aiming to optimize the technical route of sodium ion battery energy storage application and accumulate new experience in the field of electrochemical energy storage.
