2. Excellent rate performance--- room temperature 2C Rate：78% VS 62%(Whatman)

3. Excellent magnification consistency--- room temperature 2C Rate Cov：0.3% VS 13.3%(Whatman)

4. Excellent cycle performance---80% Fading：30cycls VS 10cycls(Whatman)

二： Product parameters:

三: Experimental process:

Prepare the new nickel iron manganese sodium electrode, and the coin cell assembly process is as follows:

Diagram of the assembly sequence of the coin cell:

Negative electrode shell→ spring→ gasket→ electrode→ separator→ sodium sheet→ positive electrode shell, Among them, before assembling the electrode, separator and sodium sheet, electrolyte needs to be dropped, and the amount of electrolyte needs to be completely soaked in the electrode and separator.

Test conditions:
