High discharge rate 26700 sodium ion battery for e bike motorcycle
Main Feature of CSiT 26700 sodium ion cells:
● Non-flammable. Sodium-ion batteries exhibit good chemical and thermal stability. When subjected to extreme tests such as overcharge, over-discharge, short circuit, and nail penetration, sodium-ion batteries do not catch fire or explode, and their thermal runaway temperature is much higher than that of lithium batteries.
● Could discharge to 0V. This advantage allows sodium-ion batteries to be safely discharged to 0V, making them more secure during storage and transportation, without the risk of over-discharge
● Wide discharge temperature range. Sodium ion battery can be discharged at the temperature of -40~80℃,even at -40℃, the discharge capacity is over 75%, which is much better than lithium ion battery.
● More environmental. The negative electrode of sodium-ion batteries can use aluminum foil as the current collector, which is cheaper and more environmentally friendly than copper foil. From production to disposal, sodium-ion batteries have a relatively smaller environmental impact throughout their entire lifespan.
