A team from the Canadian Light Source (CLS) in Saskatoon used high resolution CT scans to image the inside of a jellyroll type lithium batteries.

This type of energy source use a Swiss roll of metal coiled inside to generate a charge, with manufacturers cramming in as many folds as they can in order to generate as much energy as they can.
But wear and tear on the battery, such as charging for too long or overheating from prolonged use, can lead to components reacting and producing gas.
As gas builds up, so does the pressure, causing the layers to warp and the battery to swell.
Toby Bond, a scientist at CLS, carried out tests on a standard jelly-roll style battery, charging and discharging the battery and imaging the results.
Previous work showed that the gasses produced include carbon dioxide, carbon monoxide and methane – which could ignite.
Comparing before and after scans of the battery revealed the effects of the gas on the battery, causing pillowing on the structure.
While the effect may be small, it can make any existing faults in the design much worse.
Before the experiment, scans revealed the imperfections in the design, caused by manufacturers cramming in as many energy-producing layers as they can
After misuse - when the battery is charged and discharged multiple time - gas is produced, which causes the sheets to warp
Comparing the before and after scans revealed tiny changes to the jelly roll structure (in red). Researchers say that the process can make any existing imperfections worse, which could result in poorly made batteries melting or exploding
