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.

Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. This leads to damage of battery system enclosures.
During a lithium-ion battery overcharge, its cathode (anode) is over-delithiumed (overlithiumed), and a series of side reactions generate [8, 9]. Those side reactions produce some heat and gas, resulting in the oxidation of the electrolyte or cathode materials, and thermal runaway occurs .
Smaller explosions are often due to energetic arc flashes within modules or rack electrical protection enclosures. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.

The negative effects of overcharging include reduced energy storage and increased self-discharge rates. A battery that suffers from overcharging will not only perform poorly but will also need replacement sooner.

In the light of its advantages of low self-discharge rate, long cycling life and high specific energy, lithium-ion battery (LIBs) is currently at the forefront of energy storage carrier [4, 5]. However, as the demand for energy density in BESS rises, large-capacity batteries of 280–320 Ah are widely used, heightens the risk of thermal runaway (TR) [ 6, 7 ].
Lithium-ion batteries (LIBs) have been extensively used in electronic devices, electric vehicles, and energy storage systems due to their high energy density, environmental friendliness, and longevity.
