From the day I picked up the original Evo 4G, I realized that battery technology was, no doubt, lagging behind the devices it powered. Looking to push batteries a bit closer to the impressive power of today's mobile technology, researchers at Northwestern University have significantly boosted the power of lithium-ion batteries by making a few key changes.

To achieve such impressive performance enhancements, the researchers essentially poked millions of holes in the battery's graphene layers using a chemical oxidation process. Additionally, tweaks were made to the material makeup of the batteries, including packing in more ions and speeding up their movement by replacing sheets of silicon with a different substance.
