Degradation mechanisms uncovered in li-ion battery electrolytes
(Phys.org) —A team led by Pacific Northwest National Laboratory has uncovered information about high-demand batteries that could improve an essential component impacting their performance and longevity. ...
US says Boeing 787's design, manufacture safe
Boeing's design and manufacture of its cutting-edge 787 jetliner is safe despite the many problems encountered since the plane's rollout, including a fire that forced a redesign of the its batteries, according ...
GreenDataNet looking to use retired car batteries to power data centers
Researchers produce uniform antimony nanocrystals for energy storage
Researchers from Empa and ETH Zurich have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both ...
A battery that 'breathes' could power next-gen electric vehicles
Sales of electric vehicles (EVs) nearly doubled in 2013, but most won't take you farther than 100 miles on one charge. To boost their range toward a tantalizing 300 miles or more, researchers are reporting new progress on ...
Reducing debris threat from satellite batteries
(Phys.org) —Across a satellite's working life, batteries keep the craft's heart beating whenever it leaves sunlight. But after its mission ends, those same batteries may threaten catastrophe.
South By Southwest: Secrets, spying, chef Watson
FOMO —or the fear of missing out— is a common complaint at the South By Southwest Interactive festival in Austin, Texas each year.
Too many electrons at the lithiation front in silicon are a problem
(Phys.org) —Ubiquitous but frustrating, lithium-ion batteries fade because the materials lose their structure in response to charging and discharging. This structural change is closely related to the formation ...
Intrinsically unstacked double-layer graphene for high-rate lithium-sulfur batteries
By introducing a large number of protuberances on graphene layers during chemical vapor deposition (CVD) synthesis, scientists have fabricated intrinsically unstacked double-layer graphene with a high specific surface area, ...
Musk's remarks nudge hopes for affordable Tesla EV
Tesla unveils 'Gigafactory' to ramp up mass-market car
Tesla Motors unveiled plans Wednesday for a so-called "Gigafactory" for advanced electric car batteries as part of a plan to move from niche manufacturer to mass market carmaker.
Nickel-foam-supported carbon-nanotube electrode offers improved performance for lightweight lithium batteries
Lithium–oxygen batteries are innovative devices that generate power from atmospheric oxygen trapped inside porous, carbon-based electrodes. These batteries are significantly lighter than traditional lithium-ion ...
