An X-ray microscopy technique recently developed at the Advanced Light Source, a DOE Office of Science User Facility, images nanoscale changes inside lithium -
ion battery particles as they charge and discharge.
An X-ray microscopy technique recently developed at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has given scientists the ability to image nanoscale changes inside lithium -
ion battery particles as they charge and discharge.

So far, Jena and his team have hypothesized that the
particle may be used in the creation of an aluminum
ion battery, which has distinct advantages over the widely used rechargeable lithium
ion battery.
In it, they describe a process by which nanodiamonds — tiny diamond
particles 10,000 times smaller than the diameter of a hair — curtail the electrochemical deposition, called plating, that can lead to hazardous short - circuiting of lithium
ion batteries.
As reported today in the journal Science, the scientists used the approach to image micron - sized
battery particles as lithium
ions migrate in and out of the
particles.
In a real
battery, thousands of these
particles form an electrode, and positively charged lithium
ions embed in the electrode as the
battery charges.
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.
But if only a small percentage of
particles sop up all the
ions, they're more likely to crack and get ruined, degrading the
battery's performance.
A typical lithium -
ion battery consists of two electrodes and a liquid or gel electrolyte that carries charged
particles between them.
