Study sheds new light on why batteries go bad

Sun, 14 Sep 2014 15:52:16 EDT

A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.<img src="" height="1" width="1"/>

'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"/>
