Stanford Researchers Reinvent Lithium-Ion Batteries
Stanford researchers have found a way to use silicon nanowires to improve the lifespan of lithium-ion batteries by a factor of 10. The nanowires measure one-thousandth the thickness of a sheet of paper. As the nanowires are saturated with lithium, they expand to 4 times their original size and produce 10 times the electricity of today's batteries. The technology could power laptops for 20 hours, and drastically improve battery life in smaller devices such as mobile phones.
9 Ways to Maximize Your Smartphone Battery Life
Battery life continues to be one of the biggest limitations facing modern mobile devices. Batteries can only last so long when you're sending messages, snapping pix, and streaming media for hours on end.
Samsung Researchers Make Battery Breakthrough
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide.
Researchers Devise Fire-Resistant Battery
Adding a flame-retardant to select elements of lithium ion batteries many prevent fires, according to researchers at Stanford University. The researchers figured out how to create a nonwoven electrospun separator out of triphenyl phosphate and coated it with a heat-activated polymer.
AT&T's Latest GoPhone Runs On AA Batteries
AT&T today announced the SpareOne Emergency Phone, a simple handset meant purely to serve as a backup phone for critical situations. The SpareOne runs on AA batteries, rather than a rechargeable lithium-polymer power cell.
Now this will be revolutionary
20hrs of battery power for a laptop is awesome!!!
But when??? It would be nice not to have to carry around an extra battery, that's for sure.
these new Li-ion batteries plus carbon nanotube capacitors
230 mi EPA city
211 mi EPA highway
221 mi EPA combined (city/highway)
So, if the lithium ion battery in the Roadster could be extended then we would see:
2300 mi EPA city
2110 mi EPA highway
2210 mi EPA combined (city/highway)
Even if these numbers were halved we could shut OPEC down. Those scientists' lives are in serious jeopardy. It is good that they got the word out as soon as they did.
Let's not forget power plants that run on oil will be using more to gener...
Anyone remember the EV1?
With these new battery's, it would go 1000 miles on a 14 hour charge? I think the fully electric car may live again!
That is, if the oil companies don't kill it off first, just like the EV1....
so if we put one
this is good, but.............
Erm, not to be offensive, but isn't that the point with this?
second, this will enable manufacturers to make phones smaller. Since a smaller battery can provide better juice, they can pack a bigger camera or more memory etc.
