Looking inside battery cells - EurekAlert
<em>It is common knowledge that batteries degrade with usage. While this is certainly due to a complex combination of effects, how these effects interact and how they could be mitigated is far from being well understood – and is cutting-edge research. An important step forward has just been published in the journal Energy and Environmental Science. Working with a commercial-grade battery, a team of researchers bringing industry and academia together used neutron and X-ray imaging to identify a concrete effect that degrades performance. Surprisingly, this particular effect does not come with age: it is there since the first time the battery is put to work. </em>
