6 FAQs about [Lithium battery coating stripping technology]
Does lithium stripping affect reversibly plated lithium ion batteries?
In this study, we present a physicochemical model considering both lithium plating and lithium stripping side reactions in lithium-ion batteries. The model shows the amount of reversibly plated lithium dependent on the charging current on the surface of the graphite anode.
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.
What causes non-uniform lithium plating in lithium ion batteries?
Manufacturing defects in the anode can induce non-uniform lithium plating, which significantly impacts the safety and cycle life of lithium-ion batteries. This study investigates the lithium plating mechanism induced by overhang failure defects, characterized by an anode that is 7 mm shorter than the cathode.
What is a'stripping-Plateau' in lithium ion batteries?
Simulation results show the typical features of the “stripping-plateau”, which is often observed during discharge after Li plating occurrs. Moreover, a similar feature is observed at the onset of Li plating, which can serve as an indicator for lithium plating in lithium ion batteries during charging, for example, of electric vehicles.
What is a physicochemical model for lithium plating and lithium stripping?
A physicochemical model for lithium plating and lithium stripping is developed. The characteristic voltage plateau due to lithium stripping is simulated. The voltage plateau corresponds to the amount of previously plated lithium. Simulated amount of plated lithium corresponds to a former neutron diffraction study.
