Electrochemical pre-lithiation negative electrode architecture: BYDRecent Research Landscape

Unstable solid-electrolyte interphase formation leads to rapid capacity fade and safety risks. Chemical treatment of the negative electrode plate stabilizes the interface to extend cycle life.

What technical problems is BYD addressing in Electrochemical pre-lithiation negative electrode architecture?

Irreversible initial capacity loss

(73)evidences

Irreversible lithium consumption during the first cycle depletes the active material pool. Mitigating this loss increases the overall energy density and cycle life of the battery system.

Initial capacity loss

(72)evidences

Irreversible consumption of lithium ions during the first charging cycle reduces energy density. Compensating for this deficit prevents premature capacity decay and extends cycle life.

Initial irreversible capacity loss

(55)evidences

Lithium ions are consumed during the first cycle to form the solid electrolyte interface, reducing energy density. Compensating for this loss prevents premature capacity decay and improves cycle life.

Irreversible initial capacity loss

(37)evidences

Consumption of active lithium during the first charging cycle limits energy density. Mitigating this loss increases the total available discharge capacity of the cell.
