Lithium deposition electrochemical sensing: BYDRecent Research Landscape

Uncontrolled metallic lithium plating during fast charging causes irreversible capacity loss and catastrophic thermal runaway risks. These innovations utilize high-frequency impedance spectroscopy to detect phase transitions and prevent electrode degradation.

What technical problems is BYD addressing in Lithium deposition electrochemical sensing?

Inaccurate internal state estimation

(79)evidences

Uncertainty in real-time remaining capacity and voltage thresholds leads to premature power loss or battery over-discharge. Precise detection prevents unexpected vehicle immobilization and cell degradation.

Inaccurate internal thermal state

(43)evidences

Uncertainty in predicting time-to-charge and discharge limits under varying energy loads. Precise estimation prevents operational downtime and battery overstress.

Undetected internal lithium plating

(40)evidences

Lithium plating and self-discharge lead to catastrophic thermal runaway and battery failure. Identifying these hidden defects during testing prevents hazardous field failures and improves pack reliability.
