Re: So in conclusion
Lithium Titanate Oxide batteries are another form that offers very high number of cycles (20k plus) along with even higher discharge / charge rates, (10 to 50 'C' rates,) and operate in a much wider temperature range than LiFePo.
The main drawback at this time is cost, and a lower energy density rather limits use in mobile applications. They are even more stable than LiFePo, and the ability to operate down to -40°C is very attractive for off grid use in harsh climates.
For stationary battery systems, the lower energy density isn't as much of an issue as is the cost, however, they don't have that nice flat voltage curve, so the electronics needs to be setup to deal with that as well..
The BIG bugaboo with almost ALL of the so called 'green' energy is the variable nature of the beast. Once energy storage improves, (perhaps pumped vanadium electrolyte,) then it will make much more sense to avoid the carbon cycle.
BTW, in the Pacific Northwest, specifically Central Washington, public utility districts that invested years ago in hydro, have the cheapest power rates in the country. Less than 2.9 cents per kWh for residential use, with industrial rates that can be even less than that.
In the infinite wisdom of the occupants of the Pugetopian corridor, (primarily Seattle and it's surrounding population of moonbats,) the people of Washington State passed a referendum declaring hydro to be 'non-renewable' thus creating all kinds of political issues that plague the entire system.
