The new battery isn't ready for commercial development, but it shows great promise

A new battery material created by researchers from the Massachusetts Institute of Technology (MIT) could lead to much faster recharge times for batteries.

MIT professor Gerbrand Ceder and researcher Byoungwoo Kang said the material can discharge energy and recharge nearly 100 times faster than batteries currently used in mobile phones.  Lithium-ion batteries are widely used in laptops as well, and could allow longer battery life and faster recharge time if a user is away from a power source for long durations of time.

"The ability to charge and discharge batteries in a matter of seconds rather than hours may open up new technological applications and induce lifestyle changes," Ceder and Kang sad in the latest edition of Nature.

The duo created a small battery that normally takes six minutes to charge, but used their new traffic flow to recharge the same battery in just 10 to 20 seconds.

It was widely believed the ions and electrons inside the battery moved too slowly, but the researchers noticed that wasn't the case.  They focused on how ions enter nano-scale tunnels aimed at moving electrons around the battery, and eventually created a lithium phosphate coating that helps push ions to the nano-scale tunnels.

Rechargeable lithium batteries used today have the ability to store high amounts of energy, but don't normally release that power, so they discharge very slowly.    

The battery has been supported with federal research money, and two companies have already licensed the technology, MIT announced.  It'd be possible to start mass producing the batteries in two to three years, the MIT researchers said.

Australia uses 240 volts, and without Nuclear Power Generation, Granted it has much smaller consumer demand because of the Population differences, Funny thing is though, I started reading this thread a few hours ago and the Power went out completely across town.

Plus Australia by law will have only Energy Efficient Lighting available, which might help offset energy needs to an extent.
Plus I did hear some talk about the Government upgrading the Power grids so they were all computer controlled so they would have higher efficiency.

"Plus I did hear some talk about the Government upgrading the Power grids so they were all computer controlled so they would have higher efficiency."

Talk is cheap... Maybe one infrastructure project at a time? Start out with the broadband roll-out, please... Most of our power grid is already on a SCADA system of some sort, but the seperate companies don't have inter-connects between their systems. Not to mention that the loss of a grid, say in Perth, cannot be easily supplemented by a grid in SA. Distance is a factor, but total power generation nation-wide is just barely adequate. Gas fired power could be brought on line faster, but it would still take several hours to get a GFPS on the grid. Power grids are perhaps the most complicated systems of any nation's infrascructure. Very few people really understand just how complicated they truly are.

The Government isn't building the NBN, hence why they had the tender process to find an ISP that would.

I agree, the power systems are complex, but some upgrades to increase efficiency would be a good way to cut down our carbon foot print and hopefully lower prices.
