The stressful life of high-capacity electrodes

NanoWerk.com - Thu, 01/10/2019 - 11:16
One of the persistent challenges associated with electrode degradation and battery failure is the stress induced by ion intercalation, companied by large volume fluctuation of electrode materials. Although researchers have developed numerous in situ microscopy and spectrometry technologies that provided valuable insights into the impacts of the stress buildup and release, the strength of the localized stress at the micro- and nanoscale remains poorly understood. In new work, researchers have developed an in situ solution to quantitatively measure the localized stress on electrodes.
