Lithium iron phosphate battery has large initial capacity decay

An efficient regrouping method of retired lithium-ion iron phosphate

Lithium‑iron phosphate (LFP) batteries have a lower cost and a longer life than ternary lithium-ion batteries and are widely used in EVs. Because the retirement standard is that the capacity decreases to 80 % of the initial value, retired LFP batteries can still be incorporated into echelon utilization [3] .

6 FAQs about [Lithium iron phosphate battery has large initial capacity decay]

What are the challenges in early life prediction of lithium-ion batteries?

A major challenge in the field of early life prediction of lithium-ion batteries is the lack of standardized test protocols. Different research teams and laboratories adopt various methods and conditions, complicating the comparison and comprehensive analysis of data.

Why are lithium iron phosphate batteries undercuting electricity storage capacity?

It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25 per cent in practice.

What are the aging characteristics of lithium-ion batteries?

Aging characteristics of lithium-ion batteries throughout full lifecycles. During the initial stages of use, LIBs often demonstrate excellent performance. The formation of the SEI layer on the anode surface is ongoing, leading to the consumption of some lithium ions.

Do lithium ions migrate to the anode if a battery is fully charged?

"Our investigations have shown that even when the test battery cells are fully charged, lithium ions remain in the crystal lattice of the cathode instead of migrating to the anode. These immobile ions incur a cost in capacity," says Daniel Knez from the Institute of Electron Microscopy and Nanoanalysis at TU Graz.

How does a semi-empirical model describe the degradation of lithium ion batteries?

During the degradation of LIBs, there are often internal degradation mechanisms such as lithium plating and SEI growth. A semi-empirical model uses formulas to quantify the changes in these parameters and maps these changes to capacity/RUL.
