Instant Battery Recharging Discovered by MIT

The EETimes broke a story that the Massachusetts Institute of Technology (MIT)revealing a recharge rate "as little as 10 seconds) instead of six minutes ormore per cell."

Now am I challenged in my perception of time or is thatfaster than I can pump gas into a car?

The simple story on how they got a 36 X improvement toachieve virutally instant re-charging is they discovered that the chemicallithium iron phosphate mostly worked at the surface level.

So they created tunnels to create more surface. ;-)

The report does not mention any reduction in the weight. Andit makes sense to me that if you have removed material to create tunnels, youare carrying less weight.

The EETimes contiuned with durablity compartable to bulkmaterial in testing so far.

An additional benefit is all this ‘tunnelling' allow formore energy to be deliver out of thebattery. Enough juice can be had to deliver performance on a par with gasengines.

The BATT Program is supported by the U.S. Department ofEnergy Office of Vehicles Technologies (FCVT) tohelp develop high-performance rechargeable batteries for use in electricvehicles (EVs) and hybrid-electric vehicles (HEVs).
