6 FAQs about [Lithium battery pack aging test method]

What is the aging process of a lithium ion battery?

The aging process consists of constant current charging and constant discharging with a rest between them. The battery is made of LiFePO 4 (LFP) cathode and carbon anode; the nominal capacity is 100 Ah. Seven SBCs are aged at different environmental temperatures and current rates, and the test specifications are listed in Table 1.

Why is a quick determination of the ageing behaviour of lithium-ion batteries important?

For the battery industry, quick determination of the ageing behaviour of lithium-ion batteries is important both for the evaluation of existing designs as well as for R&D on future technologies.

What is the aging diagnosis of batteries?

What are the aging experiments for battery cells and the battery pack?

The aging experiments for battery cells and the battery pack are carried out. The aging process consists of constant current charging and constant discharging with a rest between them. The battery is made of LiFePO 4 (LFP) cathode and carbon anode; the nominal capacity is 100 Ah.

Does lithium plating increase the aging rate of a battery?

Lithium plating can drastically increase the aging rate of the battery and is therefore discussed separately from the anode materials. The lithium insertion potential of graphite is close to the potential of lithium metal deposition, so lithium plating is very common in LIBs. In theory, lithium deposition does not occur thermodynamically.

How to predict lithium-ion battery life?

Generally, health prognostic and lifetime prediction for lithium-ion batteries can be divided into model-based, data-driven, and hybrid methods . One type of model-based method is based on empirical or semi-empirical models of the degradation curve under specific aging conditions.
