Posted on 06/04/2013 2:09:53 PM PDT by Red Badger
The University of Wollongong has reached a breakthrough with its research on lithium-ion batteries which could make electric vehicles (EVs) more viable in the near future.
The universitys Institute for Superconducting & Electronic Materials (ISEM) has used a new Germanium-based material, capable of storing five times more energy than a conventional lithium-ion battery.
Researchers at the university believe this new technology to EVs could at the very least double the distance that the car can travel on a single charge.
And the benefits dont end there, with the new batteries bringing a significant reduction in charging times, and a relatively inexpensive manufacturing technique.
The price of Germanium is higher than materials currently used to make batteries, but Professor Zaiping Guo from ISEM is confident that prices could fall under mass production.
The novel anode materials are very simple to synthesize and cost-effective, Ms Guo said.
They can be fabricated in large-scale by industry and therefore have great commercial potential.
Were truly excited about this breakthrough and are looking forward to transitioning this technology to the commercial marketplace.
As well as improvements to EVs, the new battery technology could also be used in consumer electronics - such as mobile phones and laptops - and is even capable of grid-scale energy storage.
I`ll believ it when I see it, in the meantime, “Drill baby, drill!”
This is how Tesla is going to make a affordable version of it’s model S that can travel cross country on a single charge.
I’m all for competition between energy sources.
I’ll be ecstatic to drive a vehicle powered by American coal when the price is right.

Me too. But ONLY between free market companies. I believe technology will soon be available to power a full size car to run 500 miles (not 50 miles) and recharge in 15 minutes (not 15 hours).
But what burns me up is Obama throwing trillions of dollars at green energy boondoggles only to have these companies go bankrupt.
Gotta love it, car batteries made out of recycled CK722s ;-)
Can someone with a science background help me- is this a break through for lithium batteries or discovery of Germanium batteries....
If the new material can store 5 times the energy of current Li-ion batteries, why would it only about double the range of electric cars using it?
Anyway, sounds like good stuff. I’m not opposed to electric vehicles in principle, it’s just that so far their practicality, due to range, charging times, charging infrastructure, electrical supplies (all this electrical power will have to come from somewhere), etc have made me skeptical of their utility and “greenness.”
The anode of the battery is a germanium based material.........
‘Power’ is a logarithmic function.
30 dBm of power is 1 Watt, 33 dBm of power is 2 Watts, 36 dBm is 4 Watts, etc.
I have a substance that can send cars even farther. Most vehicles are already capable of using it without ANY modifications. It's called gasoline.
That stuff is evil devils piss..........
Hype. Or at least premature. Little practical gain after a few years work.
Note the comments at the bottom.
One possibility might be that the new design is significantly heavier than the old design and can't be scaled down. You might end up with additional range but carrying a much heavier payload.
Superconductivity and cold fusion, the if only technologies.
What you stated would be absolutely correct for sound but for HP in electric motors.
796 Watts = 1 HP
1492 Watts = 2 HP
3184 Watts = 4 HP... all quite linear.
T = HP 5252 / RPM
T= Torque In Ft/Lbs
HP = horsepower
RPM = revolutions per minute (rpm)
Again, a linear equation.
To know why 5X power storage only relates to 2X range we would need to know 1) Is this typical reporter math? or 2) Is the discharge rate of the battery limiting the range?
I think #1 is the most likely answer but will not discount #2
You had to know the Germans were somehow involved.
Now, that's progress. Like buying a conventional car with a two gallon tank!
Technology like copper wires over an inch in diameter? You'll get 5 miles out of a kWH at best in your car so you'll need 100kWh (assuming no losses). 100 kWh at 400 volts and 15 minutes (assuming no charging losses) is 1000 amps. That's assuming the generator is in your shed 50 feet from the car, otherwise add to the wire size.
Look for Jay Leno demonstrating his steam powered car.
Great vehicle when you are not in a hurry to go anywhere.
Now if they can do the same thing with Carbon.... and/or Silicon, both in the same column of the periodic table as Germanium.
Carbon and Silicon are plentiful. They have recently come up with Silicene and Germanene analogs to Graphene.
Another step closer to telling the troublemakers they can keep their oil and use it to make camel lube.
Better American nuclear.
Politicians are always confusing energy sources with energy storage. A rechargable batter is not an energy source. It takes oil, gas, coal, hydro, etc. to “create energy.” Better rechargable batteries generally make electric cars run better and less reliable sources of energy (solar, wind, etc.) more practical.
Or Lead is also in same periodic table column as Germanium.
Either up or down the elements in that group can be plentiful. Only in the middle are they scarce.
Back before WWII, an additive was made for gasoline using germanium that prevented knock. Later, came a more effective analog using Selenium. Finally, a very effective analog using Lead was developed. Of course tetra ethly lead made sense when there were 10,000 cars on the road, but less so when there were 10 million cars on the road.
You cannot discuss the viability of an electric car unless and until you include in the discussion:
1. The life span of the battery under real world conditions
2. Cost of replacement of that battery
3. Cost of disposal/recycling of that battery
Of course, if government $ub$idy is involved, you may ignore the content of this post.
Because people will be able use the heater or air conditioning.
So flower power is real? Nebber woulda thunk it.
I second that motion. Nothing is more proven than gasoline, derived from oil, as an efficient mover of vehicles. The only way that battery/electric vehicles do well, is if governments force people out of their cars. They can't make enough battery cars for all of us, at an affordable price point. If they tighten restrictions on who is allowed to drive and own cars, then the reduction of cars on the road will make the percentages of electric cars rise higher of the total cars on the road. Gasoline is efficient, the technology is very mature, and it's safer for the environment.
The major problem with lithium batteries longevity has been the anode deterioration over time. If this solves that problem, then 1,2 and 3 are no longer a factor..........
New bus system tops off batteries in just 15 seconds:
At a shopping mall on my way home I stopped and watched them install an electric car charging station. The men were wrestling with 1 inch diameter stranded copper, it was not easy.
Should have said volts times amps times time.
Real confidence requires "will".
We use 1 inch stranded copper cable in our products here where I work everyday. It comes on huge spools requiring forklifts to move. The guys installing the station you saw were probably not used to having that size cable to work with...........
I’m not sure what you’re talking about. The subject here was how much energy, in units of e.g. Watt-hours, or Joules, etc the battery can store. The article wasn’t clear, however, on whether that was an increase in energy/volume or energy/mass. Assuming the article meant that this technology would allow 5 times the energy volume and mass density, I would assume that it would allow 5 times the range for a same-sized (in terms of mass and volume) battery. A five-fold increase in battery energy density is a huge deal, btw.
That's something people always miss when they're talking about fast charging really high capacity batteries like these - massive currents that would require huge conductors. Presumably one could go to even higher voltages, although I think there's a limit to how high of voltages you want inside a car.
I think the Tesla is a beautiful car — think the same of the Fisker-Karma. Just don’t like the government subsidies [on both ends of the purchase] for a technology that very few people will pay for in its current state.
