Henry,
The Imara cell is targeted at high-power applications. The Zebra battery, in addition to the operational challenge of operating at nearly 500 degrees F has approximately 150 W/kg power. This is not a feasible solution for hybrid and short range PHEV's which Imara is targeting. These vehicles are limited today by power capabilities of batteries. With Imara you get the cycle life of an A123 iron phosphate but without the huge sacrifice of energy density.
Thanks for you interest!
