Abstract
A battery cell which includes at least one negative electrode, at least one positive electrode, and at least one electrolyte, the battery cell further including at least one electroactive material which may be prompted to undergo a change in volume and/or shape by way of an application of a voltage. A battery is also described which includes at least one battery cell, the battery further including at least one electroactive material which may be prompted to undergo a change in volume and/or shape by way of an application of a voltage. A method is also described for compensating for changes in volume and/or shape in a battery cell and in a battery.
Claims15
A battery cell which includes at least one negative electrode, at least one positive electrode, and at least one electrolyte, the battery cell further including at least one electroactive material which may be prompted to undergo a change in at least one of a volume and a shape, by way of an application of a voltage.
A battery including at least one battery cell, each of the at least one battery cell including at least one negative electrode, at least one positive electrode, and at least one electrolyte, the battery cell further including at least one electroactive material which may be prompted to undergo a change in at least one of a volume and a shape, by way of an application of a voltage.
A battery including at least one battery cell, wherein the battery further includes at least one electroactive material which may be prompted to undergo a change in at least one of a volume and a shape by way of an application of a voltage.
A method for compensating for changes in at least one of a volume and a shape in a battery cell which occur during at least one of a charging process and a discharging process of the battery cell, the battery cell including at least one negative electrode, at least one positive electrode, and at least one electrolyte, the battery cell further including at least one electroactive material which may be prompted to undergo the change in the least one of the volume and the shape, by way of an application of a voltage, the change in the at least one of the volume and the shape occurs in the active material composition of at least one of the negative electrode and the positive electrode, the method comprising:
- compensating by way of a counterdirectional change in the at least one of the volume and the shape of the electroactive material.
