Economical 18650 Cylindrical Sodium-ion Battery Cells for two wheeler

Main Feature of CSiT 18650 sodium-ion batteries
● Support fast charge. Sodium ion battery cell could support 3-4C fast charge rate, with charging management system integrated, it could be charged 70% capacity within 15 minutes.
● Support -40℃ low temperature discharge. The electrolyte and electrode materials of sodium-ion batteries mainly adopt materials with more stable physical properties, thus exhibiting excellent performance in extremely low-temperature environments.
● Long cycle life. CSIT cylinder sodium-ion battery cycle life is over 2000 times,which is much longer than NCM lithium ion battery.
● Cost saving. Sodium is one of the most abundant elements in the Earth's crust, with its abundance far exceeding that of lithium.This characteristic gives sodium-ion batteries a significant advantage in terms of raw material supply, providing a solid foundation for large-scale production and widespread application.
● Good safety performance, It won’t explode even puncture it with a needle.
● Cylinder shape, easy to connect in series and parallel, discharge rate could reach 20C max.
