See, exactly proves my point. DOD is only 25%. If you do not cycle them much, you can make a lead acid last for years no problem. If you are doing 100% DOD, and do not with to deal with maintenance, and wish to have high coulombic efficiency, lithium is far better.
Volumetric density is a side benefit of lithium. We use it for coulombic efficiency, low voltage sag, high cycle life (much higher than lead acid, regardless of cycling bandwidth), usable capacity at low temperatures (much higher than lead acid! People always get this wrong), and higher specific energy. And lead acid sulfation and shorted cells require recycling. You can safely use a lifepo4 pack for years after degradation occurs. Lead acid is easier to recycle, but lithium ion recycling companies are dominating the space now. It is not like it was 3 years ago. Times are changing and there is no way anyone wants to throw out cobalt from a pack. LFP is much easier to recycle than cobalt based chemistries as well.
Solar2 == willprowseiv? Brand new account responding as such, at least.
Which production lithium ion recycling companies are "dominating the space" and actually recycling more than test quantities of cells? Apparently I've missed that in the past few years - links to them?
