Princeton University publishes off grid battery comparison

creeky

A scientific article from Princeton U titled

A comparison of lead-acid and lithium-based battery behavior
and capacity fade in off-grid renewable charging applications

https://www.princeton.edu/~spikelab/papers/101.pdf


I found interesting conclusions in

"these studies suggest that LFP batteries may last many times longer
than lead-acid cells in off-grid wind and solar applications and have
significant potential to reduce energy storage costs over the lifetime
of intermittent renewable energy systems."

also

"the long lifespan and good voltage performance of LFP cells suggest
they are well-suited for off-grid renewable energy systems."

and interestingly

"The LFP cells not only show the least degradation under variable
charging protocols, ... but the best voltage performance as well."

Of course it's only the research of 3 phds...

Re: Princeton University publishes off grid battery comparison

Yes, and it's also only lab research not real-world usage.

Kind of ignores practical economics as well.

BTW, I know a lot of guys with PhD's; they are the first to admit that what the lab research shows does not always hold true in the field.

In the mean time we still await real long-term results of LiFePo, as with any other new technology.
