Unfortunately, a small but significant fraction of these systems has experienced field failures resulting in both fires and explosions. A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation.
The origin of this failure is an initiating cell within a module which is somehow driven to vent battery gas and transition to thermal runaway. This initiating event is most commonly a short circuit which may be a result of overcharging, overheating, mechanical abuse, or a manufacturing defect.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
failure due to a defect in an element of an energy storage system introduced in the manufacturing pro-cess, including but not limited to, the introduction of foreign material into cells, forming to incorrect physical tolerances, or missing or misassembled parts.
Stationary Energy Storage Failure Incidents – this table tracks utility-scale and commercial and industrial (C&I) failures. Other Storage Failure Incidents – this table tracks incidents that do not fit the criteria for the first table. This could include failures involving the manufacturing, transportation, storage, and recycling of energy storage.
Root Cause of Failure: Design, manufacturing, integration/assembly/construction, or operation. Affected BESS Element: Cell/module, controls, or balance of the system. The study analyzes the proportion of failures associated with each root cause and BESS element, the relationship between the two, and trends in failure types and rates over time.
