Can lithium batteries of different thicknesses be used interchangeably

Do electrode thickness and porosity influence the final capacity of lithium-ion batteries?

This study has provided new insight into the relationship between electrode thickness and porosity for lithium-ion batteries whilst also considering the impact of rate of discharge. We observe that the three parameters hold significant influence over the final capacity of the electrode.

How does thickness affect lithium ion transport?

Once the thickness of an electrode is increased, transport related limitations become important [3, 4]; the required diffusion length for lithium ion transport extends, resulting in the possibility of reduced utilisation of storage materials at the extremities of the electrode, adjacent to the current collector.

What is the electrode thickness of a commercial battery?

Considering the impact of energy and power density, cost, and cycle performance, the electrode thickness of commercial batteries is typically between 50 and 100 μm . To obtain more extreme limiting mechanisms, the cathode thickness in this study varied within the range of 20–120 μm. Table 2.

Do high-energy-density batteries with thick electrodes affect lithium plating during fast charging?

The impact of high-energy-density batteries with thick electrodes on lithium plating during fast charging deserves attention, as it is crucial for the adaptability design, safety and lifespan of the battery in high-power applications.

What are lithium ion batteries?

1. Introduction Lithium-ion (Li-ion) batteries are currently the most competitive powertrain candidates for electric vehicles or hybrid electric vehicles, and the advancement of batteries in transportation relies on the ongoing pursuit of energy density and power density .

Why do lithium ions elongate within a thick positive electrode?

Specifically, the diffusion pathway of lithium ions is elongated within a thick positive electrode, leading to a weakening of the diffusion dynamics of Li-ions in the electrolyte. Correspondingly, it takes longer for ions to reach the cathode surface, which delays the increase in cathode potential.
