'Holy grail' of battery design achieved: Stable lithium anode

Sun, 27 Jul 2014 16:57:08 EDT

Researchers report that they have taken a big step toward accomplishing what battery designers have been trying to do for decades -- design a pure lithium anode. All batteries have three basic components: an electrolyte to provide electrons, an anode to discharge those electrons, and a cathode to receive them. The nanosphere layer of a newly created battery design resembles a honeycomb: it creates a flexible, uniform and non-reactive film that protects the unstable lithium from the drawbacks that have made it such a challenge.<img src="" height="1" width="1"/>

Designing ion 'highway systems' for batteries

Mon, 09 Jun 2014 14:09:03 EDT

Researchers have married two traditional theories that advance the understanding of plastics for battery application. Since the early 1970s, lithium has been the most popular element for batteries: it's the lightest of all metals and has the greatest electrochemical potential. But a lithium-based battery has a major disadvantage: it's highly flammable, and when it overheats, it can burst into flames. For years, scientists have searched for safer battery materials that still have the same advantages as lithium.<img src="" height="1" width="1"/>

Scientists Pinpoint the Creeping Nanocrystals Behind Lithium-Ion Battery Degradation

Thu, 29 May 2014 11:12:44 EDT

Batteries do not age gracefully. The lithium ions that power portable electronics cause lingering structural damage with each cycle of charge and discharge, making devices from smartphones to tablets tick toward zero faster and faster over time. To stop or slow this steady degradation, scientists must track and tweak the imperfect chemistry of lithium-ion batteries with nanoscale precision. Scientists have mapped the nanoscale dynamics of lithium-ion charge cycles and discovered never-before-seen evolution and degradation patterns in two key battery materials.<img src="" height="1" width="1"/>
