New Hydrogen-Silicon Electrodes Greatly Improve Lithium Ion Battery Performance and Life

Ovidiu Sandru — Thu, 06 Jun 2013 10:12:52 +0000

A new kind of electrodes for lithium ion batteries has been invented at Stanford University. They greatly improve the performance of a lithium ion battery and are made of silicon and conducting polymer hydrogel, a spongy material that resembles the one used in contact lenses. “We’ve been trying to develop silicon-based electrodes for high-capacity lithium-ion […]

A newly invented material could revolutionize many industries at once. Discovered by a collaborating team from three U.S. universities, the metal is the lightest material ever discovered – so light it can actually sit on a dandelion. The new material’s density is 0.9 milligrams/cubic centimeter, and Styrofoam, one of the lightest so far, is 100 […]

The big problem with nowadays' batteries is that they charge and discharge slowly. They can be made to charge and discharge faster at the price of their shortened lifetime, but that's not a solution at all. Supercapacitors may offer fast charge/discharge rates, but their capacity is just not very high. A hybrid of these two would be perfect.
