My laptop battery can give me just under 3 hours of juice, which is far under my needs. But it looks like that might change in the future. Some smart researchers at Hanyang University in South Korea have new Lithium batteries that can last eight times longer than current models.

How did they do it? By using cathode materials in the batteries and replacing the less-efficient graphite with more-efficient silicon. Does that mean I am going to get a 24-hour battery? Well I certainly hope so!
