Sodium Ion Batteries

Sodium ion batteries sold by EVK company usually have good safety. Compared with some other battery types, sodium ion batteries have relatively low risk of safety problems such as thermal runaway under normal use. They are relatively stable under abnormal conditions such as overcharge, overdischarge and short circuit, and are not easy to cause severe safety accidents. Of course, the safety of any battery technology needs to be constantly verified and improved in practical application and long-term practice. But in general, sodium ion batteries have certain advantages in safety.
The sodium ion battery sold by EVK has the following advantages: 1. Cost advantage: sodium resources are abundant and widely distributed, and the cost of raw materials is relatively low. 2. Good high and low temperature performance: it can work in the temperature range of -40℃ to 80℃, can maintain the discharge capacity exceeding the rated capacity at both extreme temperatures, and can realize efficient charging at -20℃ 3. 2 Good safety: Because the internal resistance of sodium ion battery is higher than that of lithium ion battery, the instantaneous calorific value is less in safety tests such as short circuit. In addition, the sodium ion battery uses aluminum foil with better stability as the negative current collector, which can be completely discharged to 0V before transportation, and the transportation safety is also higher. 4. fast charging speed: the sodium ion battery has fast charging speed, and it can be overdischarged to 0V without safety problems. 5. Strong substitutability: It can be used as a supplement or substitute for lithium-ion batteries in some application scenarios. 6. EVK company can customize the products needed for customers!
