Exploration of sodium ion battery technology

The unique advantage of sodium ion battery has a great development prospect in the future. Tianneng is committed to the research on sodium ion battery and is at the forefront of science.

Low cost

Rich in sodium resources.

Sodium resources are more evenly distributed.

Cathode materials can avoid precious metals.

Aluminum foil can be used as negative collector material

High security

The internal resistance of sodium ion battery is high, the current in the circuit is lower and the instantaneous heat is less when the battery is short-circuited.

Sodium ion battery has higher stability than lithium battery.

There is no over-discharge of sodium ion battery, and the positive electrode can be discharged to 0V without affecting the subsequent use.

Sodium battery is easy to be passivated and deactivated when the heat is out of control, so the safety test performance is better.

Good performance at low temperature & good magnification performance

In the case of the same concentration electrolyte, the ionic conductivity is higher and the fast charging performance is better than that of lithium electrolyte.

The normal working temperature range of sodium ion battery is from-40℃ to 80℃, and the capacity retention rate of some products can reach 88% at-20℃, which is significantly better than that of lithium iron phosphate about 60-70%.
