Scientists boost battery strength with small holes (BBC)

[eppur_se_muova]

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.

Fast movers

A mobile phone battery built using the Northwestern techniques would charge from flat in 15 minutes and last a week before needing a recharge.

1. Okay, going to poke holes in my laptop battery

I post my results after I am done.

Better Batteries

New technology improves both energy capacity and charge rate in rechargeable batteries

EVANSTON, Ill. --- Imagine a cellphone battery that stayed charged for more than a week and recharged in just 15 minutes. That dream battery could be closer to reality thanks to Northwestern University research.

A team of engineers has created an electrode for lithium-ion batteries -- rechargeable batteries such as those found in cellphones and iPods -- that allows the batteries to hold a charge up to 10 times greater than current technology. Batteries with the new electrode also can charge 10 times faster than current batteries.

The researchers combined two chemical engineering approaches to address two major battery limitations -- energy capacity and charge rate -- in one fell swoop. In addition to better batteries for cellphones and iPods, the technology could pave the way for more efficient, smaller batteries for electric cars.

The technology could be seen in the marketplace in the next three to five years, the researchers said.
