Fossil fuels are produced by the decomposition of dead organisms, buried for millions of years. They produce greenhouse gasses and other pollutants, and their continued use could leave mankind as extinct as those decayed fossils. The earth does not hold an infinite amount of these fuels. Barring our extinction, the supply of fossil fuels will eventually run out, though demand for energy never will. An energy source is needed that is both eco-friendly and renewable. In other words, one that doesn’t pollute, and will never run out.

Energy experts have been looking for the next hit in energy technology which can be used as a substitute for the lithium-ions batteries that are used in smartphones, laptops as well as cars. It seems that the designers will have to rethink about the currently used li-ion battery. Researchers from the Northwestern University have designed a li-ion battery that has a higher energy capacity than the current battery.
The catch that comes with the modified anode brings about two main issues which are holding back the batteries charge capacity as well as the charge rate. The li-ion batteries operate in a manner where the lithium ions are moved between the cathode and anode. As the device uses the battery energy, the ions move from the anodeto the cathode through the electrolyte. Electrical energy moves to the device when ions diffuse through the electrolyte medium. During charging, the ions move from the cathode to the anode contrary to what happens when energy is used by a device. Read the full story
