I want some answers::

what is the energy density of these batteries:: Currently, we are doing well indeed to get over 300WH/LB of density. There have been some 500WH/LB tests, but nothing on the market.

To get to 1000 times this...you are ow talking 50KW/LB.!! This is WAY more than GASOLINE!!

This would allow a battery of 4 POUNDS to have 200KW/H of power!!

Don’t forget some of the high-density formulas out there are ALREADY seeing “catastrophic energy release” of their energy, as fires and/or explosions. This is on UNDER 300WH/LB batteries!! Imagine a battery with say 300 KILOWATT hours of energy, “going up” on someones car!!

Converted into a few milliseconds of power—that is MEGAJOULES of explosive power!! Think of an IED!!

and to recharge all of this in “seconds” would require a LOT of power in—power produces heat. heat can be dangerous...

I love new technology, but the thermodynamic laws are hard to beat.

Finally I will able to install Phaser banks on my Jeep.

These huge advances stem from a brand new cathode and anode structure, pioneered by the University of Illinois researchers. In essence, a standard li-ion battery normally has a solid, two-dimensional anode made of graphite and a cathode made of a lithium salt. The new Illinois battery, on the other hand, has a porous, three-dimensional anode and cathode. To create this new electrode structure, the researchers build up a structure of polystyrene (Styrofoam) on a glass substrate, electrodeposit nickel onto the polystyrene, and then electrodeposit nickel-tin onto the anode and manganese dioxide onto the cathode. The diagram above does a good job of explaining the process.

The end result is that these porous electrodes have a massive surface area, allowing for more chemical reactions to take place in a given space, ultimately providing a massive boost to discharge speed (power output) and charging. So far, the researchers have used this tech to create a button-sized microbattery, and you can see in the graph below how well their battery compares to a conventional Sony CR1620 button cell. The energy density is slightly lower, but the power density is 2,000 times greater. On the opposite end of the bleeding-edge spectrum — increased energy density, but lower power density — then IBM’s lithium-air battery currently leads the pack.

Energy density vs. power density for a variety of battery technologies, including University of Illinois’ new microstructured anode/cathode li-ion battery

What is W/H? Sorry, technically challenged.

Yet in every generation of man there’s a sucker who tries.
