6 FAQs about [Battery cathode pre-stripping technology]

How long does lithium stripping last in a battery?

During the charging process, lithium stripping persists in the time range from t5 to t6. Lithium plating in defective batteries primarily occurs during the initial few cycles. Subsequently, the Coulombic efficiency of the defective battery increases, indicating that lithium plating has ceased.

How effective is the stripping efficiency of cathode material?

Under the optimal conditions of pretreatment at low temperature for 5min and grinding at low temperature for 30s, the stripping efficiency of cathode material was successfully increased from 25.03 to 87.29%.

How important is cathode material in lithium ion battery recycling?

During the recycling process, the cathode material is the most critical component in lithium-ion batteries, being accountable for up to 40% of its cost . While, strong bonding ability between cathode materials, organic binder PVDF, and Al foil hinders the subsequent recovery process [14, 15, 16].

What are the disadvantages of stripping a cathode?

However, there are significant energy and chemical consumption during the stripping process, strict stripping conditions, and lots of losses of target recovered metals. For example, the crushing process generates a large amount of dust and leads to agglomeration of the obtained cathode material.

What is lithium plating & stripping?

It is known that lithium plating occurs on the graphite anode surface when the anode potential drops below 0 V, whereas metallic lithium strips back into the graphite anode when the anode potential rises above 0 V. This process is referred to as lithium plating and stripping.

What is the delay effect of lithium plating & stripping?

The delay effect is defined as the lithium plating during rest and discharge processes and the lithium stripping during the charging process. To verify the above analysis, in situ observations of the lithium plating and stripping process in the defect area are conducted using an optical battery, as shown in Figure 8 and Video S1.
