Techniques & Methods of Li-Ion Battery Failure Analysis

A battery or cell failure may be related to its performance (e.g. the battery is not up to the specification), safety (e.g. a cell/battery overheating), or leakage related (e.g. the electrolyte starts to leak from the cell container). This free webinar examines several common aspects of a Li-Ion battery failure analysis program.

White Paper: Techniques & Methods of Battery Failure Analysis

The challenge of battery failure analysis is to unambiguously identify the problem''s root cause. Fundamentally, the failure can be traced to battery/cell failure, device failure (external to the battery), or failure of the battery management control system which is either integrated into the battery itself or is a separate circuitry designed
