Debonding
As for planer-layer batteries, the component-scale debonding can initiate from micro-voids at electrode/electrolyte or electrode/current collector interfaces. For example, Sun et al. 180] reported that in a Li 2 S/LGPS/In–Li cell, the SE deformed with the local expansion of the In–Li anode during charging as observed by synchrotron X-ray tomography. Fig. 15 b shows that

Debonding
In general, debonding refers to interfacial failure, which can break the physical contact between two different phases and destroy the integrity of ASSBs. In composite electrode ASSBs, debonding takes the form of AM particle isolation [27, 179] and in planar-layer ASSBs, debonding takes the form of layer delamination [28, 180, 181].

Does debonding absorb energy?
The debonding process can absorb some energy. However, it is generally considered to be small compared to the energy absorbed by the subsequent plastic deformation of the matrix. Debonding is essential in relieving the stress triaxiality at the crack tip and hence allows the matrix to deform via plastic void growth .
What causes lithium ion battery deformation in charge/discharge cycle?
1. Introduction During the charge/discharge cycle process of a lithium-ion battery, lithium diffusion into/out of active materials drives expansion/contraction of the materials and this lithiation/de-lithiation induced deformation generally depends on the specific active materials.
How does debonding affect impact energy?
If debonding has a large range, fracture energy increases in evidence. Reducing interface strength will enable large-scale debonding or delamination, thereby increasing impact energy. Debonding power per unit area of composite materials is shown in follows: Here y is the debonding length.
How does a crack in a battery affect electrochemical performance?
The crack of the active layer is considered as an indicator of mechanical-electrochemical degradation in plenty of investigations. But it is still unclear how the cracks of the active layer deteriorate the electrochemical performance of the battery.
How does tensile stress affect battery performance?
The high tensile stress at the crack tip lowers the electrochemical potential and drives lithium to gather at the crack tip. This mechanism also potentially affects the battery performance. The relationship between concentration localization and battery fading is unclear.
What happens when a lithium battery is charged/discharged?
When the battery is charged/discharged, the lithium metal electrode experiences electrochemical plating/stripping. Lithium ions form nuclei on the electrode surface and grow into dendrites during this process.
