You made yourself clear. I completely understood you.
Why would you think olivine LiFePO4 batteries would benfit mobile devices besides energy density? I do not have much knowledge on "olivine" but I do own a high capacity 48V 20AH LiFePO4 battery pack and the cells are very sensitive. They require a BMS to balance each individual cells. Basically, 1 faulty cell could cripple the whole pack. Of course I am working with dozens of cells and a pack used on mobile devices would be much less. Maybe even 1 cell but from my understanding, lithium poly batteries are the main choice for mobile devices because of their shape and not energy density which is a shame.
Just so you understand me, I am not trying to pick an argument. I know what I and and you obviously know what you know.
"samsung or someone else is developing that will increase density ~50% over standard (1.5 times standard densities) but the cost of these is to high for mass production"
I am very much aware of this. A Korean scientist developed a method that made the cathode material porous. This, in effect, increased the surface area of the lithium up to 4x.
LiFePO4 batteries, although good, can only discharge at about 2C safely. This may be sufficient for the mobile platform but for what I am using it for, it's not enough
. I still think this chemistry is not reliable for mass marketing. A BMS takes room and it's a hassle to deal with.
I'll look into the Bringhamton University research but I doubt the increase in capacity would increase the C-rating if the chemistry is still LiFePO4. Check into the Lithium Nano Phosphate cells by A123. They can discharge at 90C!
Let me show you what discharging at 90 plus C looks like via A123 cells.
This is going way off topic. Sorry.
