High Capacity 46145 sodium ion battery for car starting
Main Feature of CSiT 46145 sodium ion battery:
● Support high rate discharge and charge. CSiT sodium cells can be charged at 3C-4C , and discharged at 3C, 5C, 20C according to the indicated data showing on spec datasheet.
● 3000 times cycle life. The charge/discharge cycle life is at least 3000 times at 0.2C 70% DOD.
● Much safer than lithium ion battery. The electrochemical performance of sodium-ion batteries is relatively stable and is safer than lithium-ion batteries during use. Sodium ion battery does not catch fire or explode during overcharge, over discharge, short circuit, acupuncture and other tests. It is easy to be passivated and oxidized in high temperature environments and does not spontaneously ignite.
● Wider operating temperature range. The normal discharging temperature range of sodium-ion batteries is -40°C-80°C, and the capacity retention rate can reach 80% at -40°C, but lithium ion battery working voltage range is -20°C-60°C.
● No over-discharge: the positive electrode can be discharged to 0V without affecting use, making the battery safer during storage and transportation.
