FAQ: Is there a fundamental difference between the LFP (LiFePO4) and LFYP (LiFeYPO4)?

Yes. The essential difference is the use of the chemical element yttrium (Y) instead of iron (Fe).

The chemical structure is in stead of LiFePO4 (LFP) changed to LiFeYPO4 (LFYP). See the chemical composition LiFeYPO4 batteries according to the manufacturer:

The essential difference is in the behavior of chemical elements yttrium and iron. While iron is very susceptible to oxidation and reactions with other chemical compounds, the element yttrium is more chemically stable, not easy to to reach with other compounds. The result is much stronger chemical stability and durability.

While LiFePO4 battery shelf-life is usually given as 3 to 5 years. For batteries using yttrium the service life is set to 10 or more years. Not for nothing did one of the leading scientists said: “Yttrium may be the iron of the future”.
