Hello All, In reading the actual article in Nature I've discovered interesting points that were not detailed in the news releases:
From the bottom of page 4 of the PDF: >Assuming that 15-25% >by weight loading of the olivine is possible in an optimized cell, we >estimate power and energy densities for a complete cell of >1,300-2,200 W kg -1 and 32-53 W h kg -1 at a 20C rate, and >2,800-4,670 W kg -1 and 18-30 W h kg -1 at a 40C rate. Such cells could >provide power densities not possible in current nickel metal-hydride >(power density 400-1,200 W kg -1 , energy density 40-80 W h kg -1 ) and >lithium-ion battery technology (800-2,000 W kg -1 , 80-170 W h kg -1 ), >and an energy density several times greater than is possible in >supercapacitor technology (4,000-10,000 W kg -1 ; 5-10 W h kg -1 ). >These capabilities, in a low-cost and ultra-safe storage material, may be >especially attractive for hybrid and electric vehicles. The specific power is predicted to be very high, which is great for drag racing and hybrids! I thought you drag racers might like to see the 2,800-4,670 W kg number to drool over. For reference, I believe the Inspiras came in at about 2000 W kg. When I look at the numbers around 1C or 1/2C it's not clear to me wether this can compete with a standard lithium ion in respect to range. I'm guessing it looks like it should come in at about 100 to 110 Wh kg which considering the error in my approximation may be close enough to TS cells. Has anyone besides me been thinking of the possibility of starting a backyard battery building Co-Op? If no one sold anything (personal use only) I imagine we could use all sorts of patented ideas and get the technology in use, at least in our own cars.
