Sony Hoping to Boost Battery Capacity By 40%
Sony is looking at sulfur to help improve the performance of rechargeable batteries. Sony says using sulfur as an electrode material can increase the energy density from today's limit of 700Wh/L to 1,000Wh/L. This boost would give a lithium-sulfur battery 40% more capacity when compared to a lithium-ion battery of the same volume. Sony would use sulfur for the positive electrode and lithium for the negative electrode. Sulfur has low voltage, but much greater capacity potential. The company is also investigating magnesium-sulfur batteries. Sony hopes to commercialize the Li-S batteries in smartphones by 2020.
Scientists Cook Up Quick-Charging Aluminum Battery
Aluminum-ion batteries may replace lithium-ion batteries in mobile devices thanks to a breakthrough made by U.S. researchers.
MIT Spinout Claims to Double Battery Life
A company called SolidEnergy Systems, a spinout from MIT, says it has new battery technology that will double the life of lithium-based power cells. The breakthrough involves a battery that replaces the traditional graphite anode with a thin, lithium-metal foil.
Samsung Researchers Make Battery Breakthrough
A research team working at Samsung has discovered a new way to make lithium-ion batteries that could double the available battery life in devices such as smartphones. The method involves covering silicon nanoparticles with graphene, which prevents the formation of silicon carbide.
Sony Seeking User Interface Design Feedback from Swedes
Sony today announced the Sony Concept for Android program in Sweden, which is a way for the company to test new user interface features for its smartphones. To start, Sony is offering 500 Swedish owners of the Xperia Z3 access to a new user experience that's based on a nearly stock version of Android 5.1 Lollipop, with some core Sony elements tossed into the mix.
Gold Wires and Electrolyte Gel Improve Battery Longevity
Researchers at the University of California at Irvine say they've found a way to increase the number of charge cycles a battery has from a few thousand to more than 200,000. Their discovery could lead to batteries that can be recharged repeatedly for years without losing capacity, which his something that happens with today's lithium-ion batteries.
