Engineers boosts battery strength & recharging speed

Weird as it sounds, but it seems like the engineers at Northwestern University in the US have managed to not only increase the charge of the battery, but also increase its efficiency!

One change involves poking millions of minuscule holes in the battery.

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

Dr Harold Kung and his team at Northwestern said they have found a way to cram more of the ions in and to speed up their movement by altering the materials used to manufacture a battery.

The maximum charge has been boosted by replacing sheets of silicon with tiny clusters of the substance to increase the amount of lithium ions a battery can hold on to.

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.

“Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today,” said lead scientist Prof Harold Kung from the chemical and biological engineering department at Northwestern.

Now, if we do that to our BlackBerry J-M1 batteries and get our bold running for a week, would that not be great?

  1. omg, this would be awesome

  2. Wow, way cool! :)

  3. I wonder which mobile phone lasted a week. Maybe a new 9900 would last 6 weeks!
