Stop Thermal Runaway with TR Sleeve

Prevent thermal runaway propagation between lithium-ion battery cells and mitigate catastrophic events.

Discover How To:

Prevent thermal runaway propagation between lithium-ion battery cells and mitigate a catastrophic event, using the revolutionary PACT TR Sleeve^TM, a critical safety solution for E-mobility equipment.

What is TR Sleeve?

TR Sleeve is a patented and recyclable paper-based material that effectively stops thermal runaway propagation between lithium-ion battery cells within electric vehicles, battery packs and renewable energy storage systems. By individually wrapping each battery cell with a super thin, fire-suppressant ThermoShield^TM paper, TR Sleeve ensures comprehensive protection without compromising the overall performance of the battery. Regardless of the cell design, batteries can be tightly pressed or stacked without potting materials or separators, achieving maximum energy density within the battery packs.

TR Sleeve stands at the forefront of safety, sustainability, and efficiency in battery technology. Its unique features not only address critical safety concerns, but also contribute to a greener and more cost-effective future for EVs, E-buses, E-bikes, E-scooters, and other modern devices that use lithium-ion batteries.

Patented and recyclable paper-based material

TR Sleeve is a patented, battery cell paper wrap that prevents thermal runaway propagation, mitigates thermal energy release, and protects both human lives and the environment. It is capable of containing thermal events that heat up to 750 degrees Celsius.

Extremely Thin Wrap

The specially coated paper employs a novel technology that actively and automatically cools a battery cell’s internal environment, limits transfer of heat between cells, while serving as a heat and flame barrier. By adding only .009 inches to each battery cell diameter, TR Sleeve ensures comprehensive protection without compromising the overall performance of the battery. It also eliminates the need for potting materials and separators.

Efficient & Effective

In countless tests conducted by independent labs, TR Sleeve suppressed thermal runaway propagation with no damage to the outside container, no escaped toxic fumes or gases and no change in oxygen level.

Eco-Friendly

Thermal Runaway can result in an explosion of smoke, fire and shooting shrapnel, often releasing toxic and lethal fumes and gases into the environment that cost human lives. TR Sleeve prevents such devastating events and can be safely recycled into landfills when maximum usage is achieved.

Certified Credentials

TR Sleeve has been endorsed by the Commercial Relocation Network, the Council on Safe Transportation of Hazardous Materials, and the International Association of Movers. It is also a preferred product for the US Department of Defense and has been awarded a special permit from the US Department of Transportation for the shipping of lithium-ion batteries, as well as passed the proposed SAE-G-27 test standard.

Applications:

EVs, E-buses, E-scooters, E-bikes, laptops, smartphones, tablets, and handheld games.

Sustainability and Innovation

Lithium-ion battery fires take a long time to smolder out on their own, all the while, emitting lethal fumes and gases. This makes them doubly dangerous to the environment. TR Sleeve’s advanced technology neutralizes this type of smoke formation such that virtually zero hydrogen and methane is produced and circulated into the air. Further, it is reusable, biodegradable and can be safely recycled in all landfills.

TR Sleeve sets a benchmark for responsible and forward-thinking solutions that prioritize both safety and environmental consciousness.

Recyclable Nature of TR Sleeve

TR Sleeve is comprised of PACT^® Thermo Shield^TM, a lightweight, pleated, paper material with a non-toxic, moisture vapor application that prevents thermal runaway, a phenomenon in which the lithium-ion cell enters an uncontrollable, self-heating state caused by extremely high temperatures, shaking or puncturing during transit. Thermal runaway can result in the ejection of toxic gas, shrapnel and/or particulates, as well as smoke and fire. If this occurs, the protective PACT^® Thermo Shield^TM wrap immediately cools the internal environment of the package, while limiting oxygen around the payload.
