Very interesting. Thanks!

I better get that powerful laser canon before it is criminalized.

“Ultra-High-Power Lithium-Ion Batteries (Could Power Laser Weapons, Cars)” Or maybe cars WITH laser weapons?= are you kidding? maybe we could have cats with lasers...

Great! Sign me up for a phased plasma rifle in the 40 watt range. None of these dustbuster phasers for me.

” I like how they save the negative news for last.”

Yes the positive news came first, creating a jolt of interest.

Excellent, I want my zap gun. No need for silencers. No recoil. Fully automatic.

Great self defense weapon against criminals. Looking forward to getting one.

Test batteries based on the new electrode....can be discharged in 10 seconds.

snip

The new high rate, the researchers calculate, would allow a one-liter battery based on the material to deliver 25,000 watts, or enough power for about 20 vacuum cleaners.

So it can power 25 vacuum cleaners for 10 seconds or one vacuum cleaner for 250 seconds, just over four minutes? 33HP for ten seconds in a quart sized package, as usual, no potential for vehicles.

Ultimately, the energy capacity of lithium iron phosphate is lower than that of other lithium-ion battery materials, making Ceder's advance of limited value

No, there are many applications where it could be used. Particularly in laser or magnetic rail gun weapons that need high amounts of energy for short bursts and then can recharge in several seconds from a traditional power source. They could also be used in conjunction with standard LI batteries in cars for quick acceleration.

I would rather have them controlled by a sight mounted on my sunglasses.

If they were set up in an array the short bursts could be as continuous and powerful as the hardware and power source could handle. Theoretically.

Me too. First for the next punk that cuts me off. Then for the gang-banger in the next lane booming sound louder than a Saturn V taking off.

Discharging in 10 seconds is much slower than discharging a capacitor. I guess they would discharge into a set of caps that would then discharge to power a pulse laser.

I once charged up a bank of large motor start capacitors and discharged them all at once across a 1 inch steel rod...it vaporized the rod....in just a tiny fraction of a second. The power level in amps during the discharge was enough to power a small city (for a tiny fraction of a second)...according to Ohms law... This sort of mega power release is the basis for limited area EMP weaponry. I would expect the power for a small EMP pulse to be generated by an explosion that sends highly magnetized material past a coil at tremendous speed...not capacitors.

Yes, and the inherent problem with fuel cells is that they cannot change the amount of energy they are generating very quickly. If you put one in a car with a these new batteries, you could have the power output set at a mid range and you could run off the batteries practically all the time, charging when cruising at a steady pace or stopped and discharging when accelerating. Great for around town.

Might even be nice for a Bonneville Salt Flat run.
