DOE/Pacific Northwest National Laboratory Increasing battery's storage capacity could allow laptops, electric vehicles to run longer The lithium-ion batteries that power our laptops and electric vehicles could store more energy and run longer on a single charge with the help of a sponge-like silicon material. Researchers developed the porous material to replace the graphite traditionally used in one of the battery's electrodes, as silicon has more than 10 times the energy storage...

Pomegranate Inspired Design Solves Lithium-ion Batteries Problems

DOE/SLAC National Accelerator Laboratory An electrode designed like a pomegranate – with silicon nanoparticles clustered like seeds in a tough carbon rind – overcomes several remaining obstacles to using silicon for a new generation of lithium-ion batteries, say its inventors at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory. "While a couple of challenges remain, this design brings us closer to using silicon anodes in smaller, lighter and...

Brett Smith for redOrbit.com - Your Universe Online Scientists led by a team at Stanford University have developed a new silicon-based electrode for lithium-ion batteries that could significantly improve the performance of the popular batteries, according to a new report in Nature Communications. In a lithium-ion battery, the electrode connects the lithium electrolyte, which is primarily responsible for power generation, with the rest of a circuit. "Developing rechargeable...

New design uses silicon nanoparticles to improve capacity and recharge more quickly Researchers at USC have developed a new lithium-ion battery design that uses porous silicon nanoparticles in place of the traditional graphite anodes to provide superior performance. The new batteries–which could be used in anything from cell phones to hybrid cars–hold three times as much energy as comparable graphite-based designs and recharge within 10 minutes. The design, currently under a...

Snake-like "Medusa front" offers "a view never before seen" to improve lithium batteries A benchtop version of the world's smallest battery "” its anode a single nanowire one seven-thousandth the thickness of a human hair "”has been created by a team led by Sandia National Laboratories researcher Jianyu Huang. To better study the anode's characteristics, the tiny rechargeable, lithium-based battery was formed inside a transmission electron microscope (TEM) at the Center for...

Battery boost A new high-performance anode structure based on silicon-carbon nanocomposite materials could significantly improve the performance of lithium-ion batteries used in a wide range of applications from hybrid vehicles to portable electronics. Produced with a "bottom-up" self-assembly technique, the new structure takes advantage of nanotechnology to fine-tune its materials properties, addressing the shortcomings of earlier silicon-based battery anodes. The simple, low-cost...

Rechargeable lithium ion batteries provide portable devices that require a lot of energy, such as mobile telephones, digital cameras, and notebook computers, with power. However, their capacity, and thus the running time of the devices, remain somewhat limited. A notebook computer thus usually runs only about two hours. The reason for this is the relatively small capacity of the graphite anode in these batteries to absorb lithium ions. A team led by Jaephil Cho at Hanyang University in Korea...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
