1. A method for determining parameters of battery pulsed heating, comprising:
(i) providing a lithium-ion battery with a reference electrode;
(ii) connecting the lithium-ion battery with a positive and negative pulsed heating device and performing positive and negative pulsed heating of the lithium-ion battery under first heating parameters, wherein the performing comprises;
putting the lithium-ion battery in a temperature chamber set at a first temperature for a first time period,
charging the lithium-ion battery at a first amplitude in a constant-current mode for a second time period, and
discharging the lithium-ion battery at the first amplitude in a constant-current mode for a third time period,
wherein the first heating parameters comprise the first temperature, the first amplitude, the second time period, and the third time period
(iii) obtaining a reference potential of an anode of the lithium-ion battery in real time during the positive and negative pulsed heating of step (ii), wherein the reference potential of the anode is a voltage difference between the anode of the lithium-ion battery and the reference electrode, and determining whether the reference potential of the anode is smaller than a threshold potential;
(iv) signaling the positive and negative pulsed heating device to adjust the first heating parameters when the reference potential of the anode determined in step (iii) is smaller than the threshold potential, wherein adjusting the first heating parameters comprises increasing the first temperature to an n-th temperature, keeping the first amplitude, the first time period, and the second time period constant, and repeating steps (ii) to (iii) until the reference potential of the anode is equal to or greater than the threshold potential; and
(v) recording the n-th temperature, the first amplitude, the second time period, and the third time period, when the reference potential of the anode determined in step (iii) is greater than the threshold potential.
