Abstract: The present disclosure includes a battery test assembly. The battery test assembly includes a container forming an enclosed cavity having sides, a top and a bottom with an opening in the top, a first electrode having a first non-electrically active coating material, a second electrode having a second non-electrically active coating material, a separator disposed between the first electrode and the second electrode the separator including an insulator material and a non-ionic liquid within the cavity, wherein the first electrode, separator and second electrode are wound in a spiral configuration within the container.

Abstract: A system for testing thermal runaway in a battery cell includes a first layer of first dielectric material at least in part wrapped around the battery cell, and a wire at least in part wrapped around the first layer of first dielectric material. The system further includes a second layer of second dielectric material at least in part wrapped around the wire, and a power source configured to supply power to the wire. In an example, the first layer of first dielectric material includes a polyimide film, and the second layer of second dielectric material includes mica. The system further includes a temperature sensor in contact with the first layer, the second layer, and/or the battery cell. A controller is to receive a temperature reading from the temperature sensor, and control a power supplied by the power source to the wire, based at least in part on the temperature reading.

Abstract: A lithium-ion battery assembly includes a plurality of battery cells in a spaced-apart and generally parallel arrangement, each cell of the battery cells extending along a central axis and having a first end portion with a negative terminal and a second end portion with a positive terminal. The assembly includes a first capture plate and a second capture plate, where at least the first capture plate defines capture plate openings corresponding to the plurality of battery cells, the first capture plate spaced from and oriented generally parallel to the second capture plate. Each of the plurality of battery cells extends between the first and second capture plates and is coaxially arranged with one of the capture plate openings in the first capture plate. The assembly optionally includes a body between the capture plates, the body defining a void for each battery cell.
