Communication—Precursors to Abrupt Capacity Loss in Li-Ion Batteries

The "sudden death" of a battery because of an abrupt capacity loss is a major cause of concern as it will leave electronic devices inoperable. Existing methodologies predict only the State of Health (SOH), Remaining Useful life (RUL) or detect abrupt capacity loss too close to the actual event, not allowing time for any corrective action. Sudden death does not happen at the same SOH, making the detection crucial. Specialized measurements or extensive number crunching are impractical for online battery health monitoring. Here, a novel lightweight framework, amenable for device implementation, with about 100 cycle advanced prediction has been proposed.
