Researchers Claim Lithium-ion Battery Breakthrough
Researchers at the Graz University of Technology (TU Graz) in Austria,have developed a silicon gel that could make batteries used in phones and laptops 10 times more efficient.
According to Stefan Koller, a researcher at TU Graz, the gel was designed for use with lithium-ion batteries and with the silicon gel it's possible to store 10 times more [power] per weight than graphite.
Koller said that to produce the gel his team had taken a hydrated silicon compound, irradiated it with ultraviolet light, and heated it to form an amorphous silicon gel. However, the problem with using silicon gel as a substrate is that it expands and contracts by up to 300 percent during uptake and transfer of lithium ions. Koller said his team had overcome this by using graphite as a buffer material.
