The Effect of Mud Cracking on the Performance of Thick Li‐Ion

Electrode cracking, which can occur during the drying process of slurry cast Li-ion battery electrodes, has the potential to improve ion transport in thick electrodes. We investigate the effect of cracking on electrode performance at different rates of discharge using X-ray computed tomography and electrochemical analysis.

Lithium-ion battery fundamentals and exploration of cathode

Emerging technologies in battery development offer several promising advancements: i) Solid-state batteries, utilizing a solid electrolyte instead of a liquid or gel, promise higher energy densities ranging from 0.3 to 0.5 kWh kg-1, improved safety, and a longer lifespan due to reduced risk of dendrite formation and thermal runaway (Moradi et al., 2023); ii)

The local lithium plating caused by anode crack defect in Li-ion battery

The main effect of anode crack defects is the triggering of local lithium plating. Lithium plating occurs when the anode surface is saturated or the interfacial overpotential is below 0 V vs. Li/Li + [16].To avoid it, the anode capacity is designed to be larger than the cathode capacity [17], and the charge current and operating temperature are limited [18].

University of Michigan Research Changes Narrative on Battery Cracking

Cracking in lithium-ion batteries is historically considered detrimental due to its impact on the battery''s performance, efficiency, and longevity. When cracks form within the electrodes, particularly in the anode or cathode, they can disrupt the uniform movement of lithium ions during charging and discharging cycles. This disruption decreases the battery''s ability to

6 FAQs about [Lithium battery cracking picture]

Can a lithium battery crack?

Li thinks this is unlikely unless the battery’s electrolyte—the liquid medium in which the lithium ions move—penetrates these boundaries, forming cracks. A custom-built multi-electrode array with 62 microelectrodes is about the size of a dime.

Does lithium fill a crack?

Continued Li ingress widens the cracks and drives their propagation, but from the rear, not the crack tip. The absence of short circuits even when a crack traverses the entire electrolyte, linking the plated and stripped electrodes, supports the observation that lithium only later fills the crack completely.

Do cracks in lithium ion batteries reduce battery charge time?

Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research done at the University of Michigan shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.

Does lithium ingress cause a crack in a plated electrode?

We show that cracks propagate through the electrolyte far ahead of the lithium dendrites, rather than the lithium metal driving the crack tip forward. We demonstrate that Li ingress on plating results in the formation of spallation cracks (potholes) adjacent to the interface with the plated electrode.

Why does a lithium separator crack?

In the intermediate cases, we observe an increased level of cracking, which may be attributed to the increasing degree of heterogeneity in the lithium concentration and thus the hydrostatic stress profiles. Furthermore, we observe that as the rate of discharge increases the fracture is increasingly limited to the separator region. Fig. 4.

Does lithium ingress and crack propagate well ahead of metallic lithium?

By tracking in situ both lithium ingress and crack propagation into the ceramic, we show that the crack front propagates well ahead of metallic lithium in the crack. On plating lithium, spallations (conical ‘pothole’-like cracks) form in the electrolyte adjacent to the plated electrode.
