Battery Failure Mechanisms Analysis

Rechargeable batteries will eventually fail (as shown in a). A combination of advanced techniques (as shown in b-e)1-3 is necessary to fundamentally understand the failure mechanisms so that we can develop novel materials to improve cell performance within a short time range.
