Magnesium oxide plays an important role in sodium-ion batteries due to its high ionic conductivity.As a solid electrolyte material, it can replace conventional liquid electrolytes, thereby increasing the energy density and safety of batteries.This is critical for modern electronic devices that seek high-performance batteries.

In addition to its use as an electrolyte material, magnesium oxide can also be used as an additive in cathode materials for sodium ion batteries.By introducing magnesium oxide, the structural stability and electrochemical properties of cathode materials can be significantly improved.The anode material is the core of battery performance, and its stability directly affects the life and efficiency of the battery.The addition of magnesium oxide is like putting on a layer of "armor" to the positive electrode material, so that it can remain stable during the charging and discharging process, thus improving the overall performance of the battery.

It is worth mentioning that magnesium oxide also has the advantages of abundant raw materials and low cost.This makes it in the enhancement of sodium-ion battery performance at the same time, but also can effectively reduce the production cost of the battery, for the commercialization of sodium-ion batteries to provide strong support.

In addition, the application of magnesium oxide at the nanoscale level has also brought a revolutionary breakthrough for sodium ion batteries.Nano magnesium oxide can significantly improve the cyclability and charge/discharge times of the battery due to its small size effect and large surface effect, thus prolonging the service life of the battery.This discovery opens up the possibility of applying sodium-ion batteries in long-time, high-intensity usage scenarios.
