100 GW
Happy happy happy !
I have a contact to get the new Lithium Titanate cells that charge in 5 minutes and have over 10000cycles
These cells are developped HERE in Quebec province and i would be really proud to test them for you
In fact they are both nano-titanate oxide (Li4Ti5O12) anode and lithium iron phosphate (LiFePO4) cathode
I should get 100 cells direct from the manufacture and to the agreement of the Dr who created them and have couples of patents.
Tese cells have hald the energy density but they can pump over 10kW per kg !!
These cells was created for the 5 minutes charge electric car platform. They are still not released
but i can get samples.
They asked for me about how many i want to have.. I said enough to power up to 40kW during 20sec.
I should get them in the next two weeks
What is probably more powerfull than nanotech? but less than the saft 150C cells?
The Lithium titanate from my source!!!
Sumarry:
The combination of lithium nano-titanate oxide (Li4Ti5O12) anode and lithium iron phosphate (LiFePO4) cathode is a leading candidate for this application. This combination of electrode materials provides a high degree of safety, long cycle life and rapid charge in 5 minutes.The advantages of Li4Ti5O12 are high stable structure without passivation, flat voltage profile of 1.5 V, high safety and low cost. The electrochemical investigation was carried out using 18650 cell with standard organic electrolyte, and the cell demonstrated a remarkable cycle life (see Fig.1). A very stable discharge capacity was obtained at a 5C discharge rate (12 minutes) and 15C charge rate (4 minutes). The capacity remained almost constant at 850 mAh/g for approximately 30,000 cycles at 100% DOD [1]. Security tests was performed on the 18650 cell in the charged state after 30,000 cycles. The crush test (see Fig 2) showed a maximum temperature of 72°C. The nail penetration test revealed that the cell reached a maximum temperature of 103°C, with a small amount of electrolyte escaping from the cell. Finally, a short-circuit test showed a maximum temperature of 63°C. For all three tests no smoke, no flames and no explosion were observed.Because of these significant and promising results, PHET (Taiwan) developed a unique system of protection for EV battery packs consisting of 18650 cells.
Same cells as shown in this larger scale prototype:
