Abstract

Claims (25)

1. A method of battery formation, the method comprising:

applying a first set of pulses, having a first frequency, to a battery, wherein the first set of pulses carry a net zero charge;

after applying the first set of pulses to the battery, measuring a first battery parameter;

applying, based on the measured first battery parameter, a second set of pulses to the battery, wherein the second set of pulses carry a net positive charge;

after applying the second set of pulses to the battery, measuring a second battery parameter; and

applying, based on the measured second battery parameter, a third set of pulses, having a second frequency, to the battery, wherein the third set of pulses carry a net zero charge.

2. The method of claim 1 , wherein applying the first set of pulses to the battery comprises applying a sequence of alternating positive pulses and negative pulses to the battery.

3. The method of claim 1 , wherein applying the third set of pulses to the battery comprises applying a sequence of alternating positive pulses and negative pulses to the battery.

4. The method of claim 1 , wherein measuring the first battery parameter comprises determining a thickness of solid electrolyte interphase (SEI) layer of the battery.

5. Method of claim 1 , wherein measuring the second battery parameter comprises determining a value of one of: a state of charge (SoC) or a voltage of the battery.

6. The method of claim 1 further comprising:

determining a value of the second frequency based on the measured second battery parameter.

7. The method of claim 1 , wherein applying the first set of pulses to the battery comprises applying sinusoidal pulses to the battery.

8. The method of claim 1 , wherein applying the third set of pulses to the battery comprises applying sinusoidal pulses to the battery.

9. The method of claim 1 , wherein applying the second set of pulses to the battery comprises applying a set of pulses, having the first frequency or the second frequency, to the battery.

10. A method of battery formation, the method comprising:

applying, for a particular time period, a first set of pulses, having a first frequency, to a battery, wherein the first set of pulses carry a net zero charge;

after expiry of the particular time period, applying a second set of pulses to the battery, wherein the second set of pulses carry a net positive charge;

after applying the second set of pulses to the battery, measuring a battery parameter; and

applying, based on the measured battery parameter, a third set of pulses, having a second frequency, to the battery, wherein the third set of pulses carry a net zero charge.

11. The method of claim 10 , wherein applying the first set of pulses to the battery comprises applying a sequence of alternating positive pulses and negative pulses to the battery.

12. The method of claim 10 , wherein applying the third set of pulses to the battery comprises applying a sequence of alternating positive pulses and negative pulses to the battery.

13. The method of claim 10 , wherein measuring the battery parameter comprises determining a value of one of: a state of charge (SoC) or a voltage of the battery.

14. The method of claim 10 , wherein applying the first set of pulses to the battery comprises applying sinusoidal pulses to the battery.

15. The method of claim 10 , wherein applying the third set of pulses to the battery comprises applying sinusoidal pulses to the battery.
