The biggest bottleneck in a modern day smartphone is its battery. Within just a few years we have gone from single core processors to quad and octa core gigahertz monsters, WVGA to full-HD displays, and 3G to 4G connectivity. However, the battery technology has been struggling to keep up. LG Optimus G, which touts latest innovation from LG Chem, has a battery rated at 3140 mAh. Thats more than double that of what Xperia X10, a handset released more than three years ago had. However, even that probably will not last a day of reasonably heavy usage. No matter which smartphone you use, your battery probably wont last 24 hours.
Researchers around the world are attempting to come up with a battery that can meet the demands of the next-gen smartphones and other mobile devices. The good news is that a group of scientists might have made some headway in Seoul, South Korea. A team led by Prof. Hyun Taek-hwan of Seoul National University claims to have increased the capacity of a lithium-ion battery by up to three times by using a nano structure of iron oxide and manganese oxide, instead of lead, as the cathode of the battery. The new battery is also believed to be more efficient, losing only 0.5 percent its performance even after numerous recharges.
