6 FAQs about [Lithium battery negative electrode collapse]

What happens if Li is trapped in a negative electrode?

When the amount of trapped Li in the negative electrode increases, the Li diffusion rate in the material decreases and it becomes increasingly difficult to lithiate the electrode.

What happens if a lithium ion battery is fractured?

Fracture in electrodes of the lithium-ion battery is actually complex, since it may involve fractures in and between different components of the electrode and the electrochemical coupling needs to be included as well. Fracture damages the integrity of the electrode structure and compromises the whole cell performance.

What happens if a lithium ion battery fails?

During the insertion and deinsertion of the lithium ions, expansion and contraction occur in the anode material, which leads to the volumetric changes. Subsequently, cracks are gradually formed, resulting in the anode fracture ( Fig. 2 ). As a result, anode failure takes place inevitably and reduces the cycle life of the lithium-ion battery.

What causes anode failure of lithium ion battery?

Additionally, anode failure of lithium-ion battery could also be caused by the formation of lithium dendrite. During the processes of charge and discharge, lithium dendrites gradually accumulate on the anode due to the uneven deposition. The persistent growth of the lithium dendrite is likely to cause the separator penetration [ 72 ].

How does a negative electrode lose capacity?

For negative electrodes, the most recognized capacity loss mechanism involves the formation of the SEI layer via irreversible reduction of the electrolyte. [24, 59] This reaction, which proceeds until the electrode surface becomes passivated, [9, 59] typically takes place in parallel with the reduction (i.e., lithiation) of the negative electrode.
