Abstract: An embodiment is directed to a battery module mounting area of an energy storage system. The battery module mounting area includes a first set of battery module compartments arranged along a first longitudinal side of the battery module mounting area, and a second set of battery module compartments arranged along a second longitudinal side of the battery module mounting area. Each battery module compartment in the first and second sets of battery module compartments includes an insertion-side through which a battery module is configured to be inserted into the battery module compartment and/or removed from the battery module compartment. The insertion-side of each battery module compartment in the first and second sets of battery module compartments is configured to be closed via an insertion-side cover to form a battery housing with a closed compartment profile that is characterized by each battery module compartment being sealed from at least one other battery module compartment in the battery housing.

Abstract: A battery housing has a body and a lid mateable with the body. The body and the lid, when mated, provide a chamber dimensioned to hold at least one battery; and a venting passageway from the chamber. At least a portion of at least one of the body and the lid comprises an intumescent flame retardant material with an expansion ratio sufficient to drive gas from the chamber through the venting passageway and to seal the chamber when the material intumesces in the event of thermal runaway of a battery housed in the chamber.

Abstract: Processes for preventing or containing a thermal runaway event in a battery cell are provided that include localizing an effective amount of a thermally decomposable flame retardant to a target site on a cell or battery, where the flame retardant is localized so as not to coat the entire cell or large portions of the cell. It was discovered that targeted localization of flame retardant material(s) improves cell safety by preventing thermal runaway under adverse operating conditions.

Abstract: Provided is a lithium ion battery including a battery can, a battery core received in the battery can, electrolyte filled in the battery can, and a battery cover assembled to the battery can. The battery can or the battery cover is provided with a pressure relief valve, and the pressure relief valve is coupled with a mesh cover defining a number of through holes therein. According to the present invention, when thermal runaway occurs to the lithium ion battery, the pressure relief valve breaks timely. Only gases and electrolyte vapor can pass through the mesh cover. Solid particles cannot pass through the mesh cover. Therefore, ignition of the flammable gases, the electrolyte vapor and the high temperature solid particles in the surrounding air afar from the pressure relief valve is avoided and the safety performance of the lithium ion battery can be improved remarkably.
