| Scientists boost battery strength with small holes
Quote:
Batteries for phones and laptops could soon recharge ten times faster and hold a charge ten times larger than current technology allows.
Scientists at Northwestern University in the US have changed the materials in lithium-ion batteries to boost their abilities.
One change involves poking millions of minuscule holes in the battery.
Batteries built using the novel technique could be in the shops within five years, estimate the scientists.
| BBC News - Scientists boost battery strength with small holes
Phone battery. Charged in 15 minutes, charge lasts for 1 week.
Is this the birth of the electric car???

The new electric cars use lithium because it can hold its charge longer.

Holes in a battery.... 
No fluids leak out?

The recharging speed has been accelerated using a chemical oxidation process which drills small holes - just 20-40 nanometers wide - in the atom-thick sheets of graphene that batteries are made of.
| Liquid's not coming out in the same way that goretex has holes and water doesn't get in. Liquid droplet size is much greater than the size of the holes.

You'll also note that they were using graphene as one of the elements of the battery; Graphene is very nearly a monofilm, and a battery's power is directly related to the amount of surface area exposed within the battery itself.
Also notice that after 150 charging cycles, it starts to lose efficacy. Though if you only have to charge once a week that is 3 years, so...maybe not so bad for phones. Cars on the other hand...

drilling holes = more surface area = higher capacity batteries.
not sure how that = faster charging tho.

Holes are awesome... they provide more speed, now they provide more power!  | |

i think its about due for a major battery breakthru. energy storing has to be near the top of all future electronic technological progress.

I can't wait for graphene tech to become mainstream.
I'm dumping all my investment money into graphene tech.
My financial advisor is still looking for a mutual fund for me.

Until you find out lithium is even harder to get and more finite than gasoline. Quote:
