Sodium-ion batteries

Sodium-ion batteries are a type of secondary battery utilizing sodium ions as the active material, boasting advantages such as high energy density, long lifespan, and low cost. The cathode material of sodium-ion batteries is typically a sodium-ion compound, while the anode material is usually a carbon material. The electrolyte commonly consists of organic solvents or aqueous solutions containing sodium-ion salts. The working principle of sodium-ion batteries involves the storage and release of charge through the migration of sodium ions between the cathode and anode.
Characteristics and advantages of sodium-ion batteries:

1. Ultra-wide temperature range: Sodium-ion batteries can start vehicles in extremely cold weather at -40℃, and can also be used in high-temperature environments up to 80℃. The ultra-wide operating temperature range enables the battery to adapt to harsher environments.

2. High safety: Via testing, sodium-ion batteries are non-flammable under various extreme conditions, and their safety performance is superior to that of lithium batteries.

3. Long cycle life: Sodium-ion batteries have a long cycle life, and as starter batteries, they can last as long as the vehicle itself, eliminating the need for replacement like lead-acid batteries.

4. Can start vehicle at 0V, easy for maintenance: Sodium-ion batteries can still start a car even when at zero voltage, and after charging, they can continue to be used without affecting their lifespan, making them easier to maintain than lithium-ion batteries.

5. Low cost: Sodium is abundant and inexpensive, which is conducive to reducing battery costs after its widespread use in the market.

6. Environmentally friendly: Sodium-ion batteries do not contain harmful substances and are environmentally friendly.
