摘要： Lithium ion batteries are provided that include materials that provide advantageous endothermic functionalities contributing to the safety and stability of the batteries. If the temperature of the lithium ion battery rises above a predetermined level, the endothermic materials serve to provide one or more functions to prevent and/or minimize the potential for thermal runaway, e.g., thermal insulation (particularly at high temperatures); (ii) energy absorption; (iii) venting of gases produced, (iv) raising total pressure within the battery structure; (v) removal of absorbed heat from the battery system via venting of gases produced during the endothermic reaction(s) associated with the endothermic materials, and/or (vi) dilution of toxic gases (if present) and their safe expulsion from the battery system. Multi-core rechargeable electrochemical assemblies are also provided that include a plurality of jelly rolls, a negative current collector, a positive current collector, and a metal case.

摘要： Battery systems are provided that include a plurality of modules positioned within an enclosed space (e.g., a room, data center or storage system), wherein at least one of the modules includes a plurality of lithium ion cells and thermal insulator(s) positioned between adjacent lithium ion cells, and wherein the battery systems offer a requisite level of safety by scaling the system such that the internally available volume of the enclosed space (measured in liters) is in the range of about 39 ± 5 times and 80 ± 5 times the amp-hour (Ah) capacity of lithium ion cell(s) positioned therewithin, and associated methods for safe deployment of battery systems in enclosed spaces. The relevant lithium ion cell(s) for determination of Ah capacity is/are the lithium ion cell(s) that is/are thermally insulated relative to adjacent lithium ion cell(s).

摘要： Casings for electrochemical elements are provided that include a container or assembly that defines a base plate, sidewalls and a top plate or lid, an overcharge electrical disconnect feature, and a vent structure associated with the container or assembly. A flame arrestor may be positioned in proximity to the vent structure. The overcharge electrical disconnect feature electrically separates the electrochemical elements from the casing when the internal pressure of the casing reaches a predetermined threshold. The lithium ion battery may also include a pressure disconnect device associated with the casing. The pressure disconnect device may include a deflectable dome-based activation mechanism, and the deflectable dome-based activation mechanism may be configured and dimensioned to prevent burn through.

摘要： Casings for lithium ion batteries are provided that include a container or assembly that defines a base, side walls and a top or lid, and a vent structure associated with the container or assembly. A flame arrestor may be positioned in proximity to the vent structure. The lithium ion battery may also include a pressure disconnect device associated with the casing. The pressure disconnect device may include a deflectable dome-based activation mechanism, and the deflectable dome-based activation mechanism may be configured and dimensioned to prevent burn through, e.g., by increasing the mass of the dome-based activation mechanism, adding material (e.g., foil) to the dome-based activation mechanism, and combinations thereof. Burn through may also be avoided, at least in part, based on the speed at which the dome-based activation mechanism responds at a target trigger pressure.

摘要： Battery systems are provided that include polymer cells/pouch cells. The polymer cells/pouch cells are structured such that, in response to an increase in pressure within the polymer/pouch cell, e.g., a pressure increase beyond a threshold level, the polymer/pouch releases gasses in a directionally controlled manner so as to facilitate withdrawal of the gasses from the battery enclosure through a vent structure that is positioned for ease of communication with the released gasses. The battery enclosure is generally sealed, e.g., hermetically sealed, and the polymer cells/pouch cells may be spaced from each other, e.g., by a support structure that may include interleaved barrier structures.
