Why use cylindrical na-ion batteries to replace Li-ion batteries?
* High safety. Na-ion batteries offer higher safety than lithium-ion batteries, it won’t explode even you prick it with a needle.
* Fast charging performance. Comparing with lithium-ion batteries, na-ion batteries is with better fast charging performance, you can charge it with 3C current, which means the battery can be fully charged within 20 minutes.
* Great low temperature performance. Sodium-ion battery could be charged at -40 ℃ and keep 80% capacity retention rate.
* Cost saving. The cost of soium ion battery can be lower than lithium ion battery in future because the storage capacity of sodium far exceeds that of lithium.
