A sodium-ion battery is a rechargeable battery that uses sodium ions as the energy storage medium. Its principle is that electrical energy is generated through the insertion and extraction of sodium ions during charging and discharging.
Sodium-ion batteries have the following advantages:
Sodium salt reserves are plentiful: Sodium is the sixth most abundant element on Earth and is widely available. Compared to lithium, sodium salts can be more easily and abundantly stored.
Low cost: Compared to lithium-ion batteries, sodium-ion batteries have a high sodium-ion reserve, are widely available and easier to purify, making this type of battery technology more economical.
High safety: Compared with lithium-ion batteries, sodium salt batteries have stronger tolerance and can work at higher temperatures and under extreme operating conditions without overheating, leakage or other safety issues.
Long cycle life: Sodium salt batteries have a longer cycle life, shorter charging time, and better stability.
Sodium-ion batteries have a wide range of applications, including but not limited to:
Energy storage systems: Sodium-ion batteries can be used in energy storage systems, offering lower costs and higher energy density, making them suitable for larger capacity energy storage needs.
Electric vehicles: Sodium-ion batteries can be used in electric vehicles, offering higher stability and lower cost, and may become a replacement for lithium-ion batteries.
Photovoltaic energy storage: Sodium salt batteries can be used in conjunction with solar panels to store electricity during the day and use it at night.
Mobile devices: Due to the high cycle life and stability of sodium-ion batteries, they can also be used in mobile devices such as mobile phones and laptops.
