Lithium Iron Phosphate (LiFePO4) Batteries

[davidbrady]

Out of the attached study comes the suggestion to keep our LiFePO4's at or around 68 deg F, discharge them moderately, and keep the discharge rate down at fractional C levels. Also, there are exciting anode and cathode technologies on the way. One of them is Lithium Titanate (Li2TiO3) which may take us to the next level. In any case, all of these technologies will likely have similar concerns for us; namely, cell balance and voltage reversal when put into series strings, strict low and high cutoff voltages, and special constant current and constant voltage charging regimens with limitations on float current. It's an exciting time to be an electrochemist, a battery material scientist, or a motorhome owner!
