The results show that the Taguchi method is an effective approach for optimizing the exchange current density of lithium-ion batteries. This paper shows that the separator thickness followed by the positive electrode thickness play the major role in determining the lithium-ion batteries response.

What is ECD at the positive electrode of a Li-ion battery?

The ECD at the positive electrode measures the rate at which electrons are exchanged between the electrode and the electrolyte. This rate is crucial as it directly affects the charging and discharging rates of the battery . Various factors influence the ECD at the positive electrode of a Li-ion battery.

How do you calculate the OCP of a lithium ion electrode?

The OCP of each electrode can be calculated with stochiometric numbers, which are the ratios of solid-phase lithium-ion concentration on the surface to the maximum available lithium-ion concentration that one electrode can contain , , .

What does ECD mean on a battery?

The ECD at the positive electrode determines how quickly the lithium ions can be extracted from the electrode during charging and how quickly they can be re-inserted during discharge. If the ECD is too low, the charging and discharging rates will be slow, and the battery will not be able to deliver high power.

What are the input factors for maximizing ECD at a positive electrode?

The proposed method involves varying six input factors such as positive and negative electrode thickness, separator thickness, current collector area, and the state of charge (SOC) of each electrode; five levels were assigned for each control factor to identify the optimal conditions and maximizing the ECD at the positive electrode.
