Description: Lithium-Ion Thermal Runaway Containment Study Within Fiberboard Boxes Details: TEST 13: 15” x 8” x 4” Folded Mailer with closure tape, B-flute with 2.0lbs of CellBlockEX within

heat sensitive textile pillow lined with fire resistant textile.

Purpose: This test was conducted to demonstrate and document the capability of CellBlockEX® to contain a thermal event involving lithium ion cells and batteries (UN 3480) within a fiberboard box.

Test Sample TENERGY 18650 9.6 Wh, 15 count @ 100% SOC (144 total Wh), installed in 1x15 tight Identification: arrangement inside of box between CellBlock® extinguishing pillows. These cells are the same as

used by the FAA William J. Hughes Technical Center and represent one of the most volatile cells commercially available.

Test Equipment: FireRod heater cartridge, 110 DC Power Supply, Type-K Thermocouples

Procedure: Single cell ignition by heating at a rate of 2°C/sec to vent and thermal runaway or 200°C. Record temperature every 1 second on the ignition cell, adjecent cell, middle cell, aft cell, box top, box bottom, and box left; record photographs and video.

The results and any data provided by CellBlock in any format (“Data”) apply only to the sample(s) tested and shall not be considered indicative of the qualities of apparently identical or similar samples.

Results: An initiation cell was heated until it experienced rapid disassembly (thermal event). The initiation cell exposed adjacent cells to heat, fire and ejected contents. The cells were assembled in close proximity to each other, but the CellBlockEX material was effective in preventing propagation of all remaining test cells (cells 2 through 15). The heat generated from the initiated thermal event melted the heat sensitive textile material as intended, dispersing CellBlockEX loose-fill. While initially there was significant smoke that exited the seams of the box, once the CellBlockEX material was released it absorbed significant quantities of the smoke as can be viewed in the video recordings. The test was performed with a quantity of CellBlockEX consistent with a ratio of 1.98 cubic inches per Watt hour (Wh) of cells, which is below the recommended quantity of 3-5 cubic inches per Wh (in/Wh) of CellBlockEX. The maximum internal temperature recorded was 722.18°C. The maxiumum adjacent cell temperature recorded was 120.33°C. The maximum external temperature recorded was 26.62°C on the box bottom. The result was positive in that:

• There was no hazardous flame or hazardous fragments that exited the package. • No outer package charring was observed. • The thermal runaway was suppressed and fully contained • The CellBlockEX absorbed the gas from the thermal event • Propagation was prevented. • No damage or leaking electrolyte was observed from adjacent cells.
