Fisker?! I thought they flopped pretty badly after the karma, which was sad because it was actually a pretty cool car. I know someone who had one and have ridden in it. I'm surprised they have any money to spend on R&D like this.
Anyways, the proposed battery makes two separate and pretty amazing claims. That it will have 2.5x the energy density of a lipo, and that it will be capable of charging fantastically quickly. To me this means more for electric dragsters than anything else. Normal batteries are capable of discharging much faster than they can charge in a fairly related matter, so it would stand to reason that not only would this battery be able to charge it's enormous amount of energy in such a short amount of time, but also discharge it in even less time. This means you could get an enormous amount of power out of a very small battery for just enough time to travel 1/4 of a mile or however long the particular drag strip is, making for unparalleled power to weight ratio. Based on some quick estimates (~165kWh for 500 miles) the battery linked is capable of being charged at over 10 mega watts, and lets say worst case scenario the battery is only able to discharge twice as fast as it charges (most lipo and nimh batteries are closer to 10x, and I don't think there are any examples of a type of battery capable of charging faster than it can discharge), then you would only need a ~50kWh battery to match the power output of Top Fuel dragsters, and based on their claim of 2.5x lighter than lipos for the same energy, that would only weigh just under 350lbs. The motor would also contribute a fair bit of weight, but that is not the real limitation and it wouldn't outweigh the battery pack. Also, with 50kWh and assuming everything else being the same as Top Fuel (it wouldn't, it would be better), and a not very efficient motor the car would be able to make a minimum of 6 passes back to back. Assuming the current standard of discharging 10x faster than charging, this would decrease the weight of the battery down to just 10kWh at 70lbs, and it would be just enough charge for a good burnout and a single pass. Of course these are some pretty extreme claims that Fisker is making, and I don't know how the technology works so maybe this is a strange battery that can charge much faster than it can discharge, so we will see what actually happens. Either way I am super excited for new battery technology.
TL;DR: Assuming these batteries are real, Top Fuel eat your heart out.
