New Lithium-Ion Battery Tech May Boost Charge By Ten Times [bbc.co.uk]
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.



That's an interesting development. Now, if they can just get the manfacturuing sorted...

It takes five years for a Chinese factory worker to punch a few million holes in a battery? No protective gear to slow them down, and charge 'em for each lost or damaged pin.

Perhaps even more interesting is the effect this will have on electric automobiles. Some manufacturers make cars that get upwards of 300 miles/charge (more standard ones looking at around 150 miles/charge). If those numbers could be 1500-3000 miles per charge we are looking at serious impact to the automobile industry.

Not to be cynical but the last time there was a big advance on battery technology that could be used in cars the patents ended up being owned by an oil compnay.

Hopefully there will be a better outcome this time.

One thing they'll have to overcome is that with ten times the power inside, the battery becomes more dangerous when a fault condition develops. An exploding Lithium battery as used in a mobile phone can already inflict serious injury. Safety will have to be even better in the future.

That's true about the safety aspect - there's an awful lot of energy stored in existing batteries, and fires have been known to cause problems.

Try not to drop or puncture a Lithium battery or you're asking for trouble.
