Abstract: The present disclosure provides for advantageous electrolyte filling systems/methods utilizing predetermined pressure/flow cycles. The disclosed electrolyte filling system enables filling of at least one jelly roll assembly under vacuum. The disclosed electrolyte filling system is capable of simultaneously filling at least two multi-core lithium ion batteries. The disclosed multi-core lithium ion batteries include a plurality of jelly roll assemblies positioned within cavities, which are further positioned within a sealed enclosure. The disclosed jelly roll assemblies are electrically connected to at least one bus bar. The disclosed bus bars include at least one flexible connective structure to electrically connect to a sealed enclosure.

Abstract: 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).

Abstract: A multi-core lithium ion battery includes a sealed enclosure and a support member disposed within the sealed enclosure. The sealed enclosure may be fabricated with a clamshell configuration. The sealed enclosure may further include at least two support members housed within individual compartments, separated by shared wall(s). The support member(s) includes a plurality of cavities and a plurality of lithium ion core members which are disposed within the plurality of cavities. The battery may further include a plurality of cavity liners, each of which is positioned between a corresponding one of the lithium ion core members and a surface of a corresponding one of the cavities. The hermetically sealed enclosure may be formed using a clamshell configuration. Structures may be included in proximity to or in contact with the lithium ion core members to control gas/fluid flow therefrom.

Abstract: 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.
