NaCR21700-2ER Sodium-ion Battery Description
Sodium-ion Battery is a kind of secondary battery that relies on sodium ions to move between the positive and negative electrodes to complete the charging and discharging work, and the working principle and structure are similar to the widely used lithium-ion batteries. Sodium and lithium belong to the same main group of elements, and both exhibit similar "rocking chair" electrochemical charge-discharge behavior in battery operation.
NaCR21700-2ER Sodium-ion Battery Characterstic
1.Abundant and widespread resources, low cost
2.High fast charging rate, and has the advantage of replenishing energy
3.Safety, no fire and no explosion in the test of safety items such as pinprick, extrusion, overcharging and overdischarging; and in the transport link, 0V transport can be achieved, reducing the safety risk of battery transport.
4.Excellent High and low temperature performance. Discharge more than 70% of capacity at low temperature of -40℃, and can be cycled at high temperature of 80℃.
