Researchers Develop Gummy Material That Could Improve Safety Of Lithium Ion Batteries
2014-02-04 13:42:28

Washington State University A group of Washington State University researchers has developed a chewing gum-like battery material that could dramatically improve the safety of lithium ion batteries. Led by Katie Zhong, Westinghouse Distinguished Professor in the School of Mechanical and Materials Engineering, the researchers recently reported on their work in the journal, Advanced Energy Materials. They have also filed a patent. High performance lithium batteries are popular in...

Why Do Lithium-ion-batteries Fail?
2013-10-17 15:36:16

ETH Zurich Lithium-ion batteries are in our cellphones, laptops, and digital cameras. Few portable electronic devices exist that do not rely on these energy sources. Currently battery electrodes contain active materials known as intercalation compounds. These materials store charge in their chemical structure without undergoing substantial structural change. That makes these batteries comparatively long-lived and safe. However, intercalation materials have one drawback: their limited...

'Popcorn' Particle Pathways Could Lead To Better Lithium-ion Batteries
2013-06-11 11:16:03

DOE/Sandia National Laboratories Researchers at Sandia National Laboratories have confirmed the particle-by-particle mechanism by which lithium ions move in and out of electrodes made of lithium iron phosphate (LiFePO4, or LFP), findings that could lead to better performance in lithium-ion batteries in electric vehicles, medical equipment and aircraft. The research is reported in an article entitled, "Intercalation Pathway in Many-Particle LiFePO4 Electrode Revealed by Nanoscale...

Improving Quality Control Of Lithium-ion Batteries Using New Technique
2013-05-10 08:10:11

Purdue University Researchers have created a new tool to detect flaws in lithium-ion batteries as they are being manufactured, a step toward reducing defects and inconsistencies in the thickness of electrodes that affect battery life and reliability. The electrodes, called anodes and cathodes, are the building blocks of powerful battery arrays like those used in electric and hybrid vehicles. They are copper on one side and coated with a black compound to store lithium on the other....

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...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
