Over the past decade, scholars and industry experts are intensively exploring methods to monitor battery safety, spanning from materials to cell, pack and system levels and across various spectral, spatial, and temporal scopes. In this Review, we start by summarizing the mechanisms and nature of battery failures.
Usually, health indicators (HIs) are first extracted from the raw test data, which are then used for the estimation of SOH. The second group of SOH estimation methods relies on numerical models and adaptive filtering, which have shown high accuracy in real-time estimation of the battery’s capacity, resistance, and other characteristics.
Diagnostics and state-of-health determination for advanced battery chemistries is very important for battery safety and optimal performance. In response to a need to eliminate battery catastrophic failures, a fast, new method to detect short circuits at any status of battery charge was developed.
Using data from the NDANEV-China, a three-tier fault diagnosis technique was crafted for early warning systems in EV batteries, which included safety thresholds, confidence interval estimation, and crucially, K-means for pinpointing voltage fluctuations.
Inherent problems can cause cell faults even before they are used (e.g., impurity and flaw at materials level). Enhancing battery safety using safety materials and advanced architecture is crucial. If there is a fire or risk of fire, move to a safe distance from the cell and immediately call emergency services.
As previously mentioned, battery safety risks include (1) mechanical, (2) electrical, (3) thermal, and (4) electrochemical abuses, as well as (5) unintentional manufacturing defects or contamination. The first four can arise anytime during the cell life, while the last introduces risks before field deployment.
