Cell phones, CD players and flashlights all wear down batteries far faster than we might wish. But theres new hope, now that researchers at the Department of Energys Idaho National Engineering and Environmental Laboratory (INEEL) have overcome another barrier to building more powerful, longer-lasting lithium-based batteries.
The INEEL team, led by inorganic chemist Thomas Luther, discovered how lithium ions move through the flexible membrane that powers their patented rechargeable lithium battery. Research results are currently published online, and in the April 24, 2003, print issue of the Journal of Physical Chemistry B.
Luther calls their translucent polymer membrane an inorganic version of plastic kitchen wrap. The team, including chemists Luther, Mason Harrup and Fred Stewart, created it in 2000 by adding a ceramic powder to a material called MEEP ([bis(methoxyethoxyethoxy) phosphazene]), an oozy, thick oil. The resulting solid, pliable membrane lets positively charged lithium ions pass through to create the electrical circuit that powers the battery, but rebuffs negatively charged electrons. This keeps the battery from running down while it sits on the shelf-overcoming a major battery-life storage problem.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
