Compared to current lithium-ion or lithium-iron-phosphate batteries, CATL's sodium-ion battery offers greater resistance to low temperatures in terms of capacity and can be recharged quickly at room temperature, while others should be warmed 40-50 degrees.
However, the sodium-ion battery also has a flaw: first, its energy density is lower, with only 160 Wh per kg, which is less than with the lithium-ion which is between 250 and 300 Wh / kg for the best students.
However, sodium-ion technology could prevent a shortage of materials, with lithium being very widely used at the moment.
