It would be remiss to ignore NiFe, since the Chinese battery makers are in full production mode.

No liquids or semi liquids in transportation.

I have read of people who are re-using lead acid batteries which have been withdrawn from automotive service, and they use DC with an AC component, for charging.

Pulse charging, became popular after Nickel Cadmium came out, to measure the internal resistance. It did something like what you describe, but also had the advantage to help break loose (spoken loosely) materials from the electrodes (or in the case of NiCd to help prevent the formation of micro-fine shorts).

Thank you very much for considering the inclusion of Nickel Iron batteries in your no doubt daunting task of discussing batteries and other storage media.

My main considration for NiFe batteries is (emergency) backup for solar PV during the hurricane season in Florida and the Southern US. The sun is shining but the power line is broken.

A second consideration would be the initial cost of installation, compared to lead-acid, and never having to dispose of these batteries.

The US Solar PV dealers/suppliers do not want to discuss NiFe batteries. The utility companies just do not want solar grid-tie, especially with batteries.

The US manufactured NiFe are expensive.

Do not forget to mention ex-Tonight Show host Jay Leno, the most famous NiFe battery user.

As if you needed another source of energy storage:please mention super-caps that are becoming available an in use by some renewable power generators.
