i am late to the party, but better late than never i suppose
so far i have read support for the edison cells, however i have not read
much about "charge" "discharge" efficiencies and "self discharge" issues with the technology.
have the chinese done something that dramatically improves these issues?
while it might be argued that efficiencies don't really matter with windpower, because we can just build more or bigger machines to do the charging, their are still questions in my mind with the iron batteries.
aside from the anecdotal claims of "they last a hundred years" much like lister engine's lasting a hundred thousand hours, the reality is much different. so i weight the lifespan differences between true heavy duty lead cells with that of the iron cells.
further i don't think a fair analysis can be made for or against the iron battery without taking all factors into account.
simply comparing amp/hrs vs years, is only a part of the story, or at least should only be taken on balance with all the other factors.
i some systems i would argue both for and against any battery technology,
the only way i can see myself clear to taking on a set of iron batteries is if they became much more commonly available, made by a first world company, and were available for a hell of a lot less money retail.
then i might seriously consider them even with their efficiency issues, higher self discharge and other inherent concerns specific to their chemistry.
in fairness, not to rain on the chinese parade, but what happens if there is a trade embargo, or tariffs, or some other political problem? what happens if the importer goes "boobs" up and files bankruptcy?
at least i would feel a lot better if there were at least a half dozen "stocking" importers of these batteries. and i would feel even better if the manufacture was decentralized a bit as well, maybe a plant in taiwan, or some other country within the region?
so anyone want to address any of these concerns?
