Trigger Cells And Isc-D

KULR’s ISC Trigger Cell is a lithium-ion cell with an implanted thermal device. It allows the cell to be triggered into thermal runaway by heating it to a modest temperature. This technology , which is licensed from NASA and NREL, allows users to test thermal runaway behavior or mitigation features in a battery pack with minimal collateral overheating of adjacent cells and other pack components.

Product Description

KULR has exclusively licensed the internal short circuit (ISC) technology, which was co-developed between the National Renewable Energy Laboratory (NREL) and NASA. The ISC device was developed to replace current archaic testing methods such as the nail penetration test. The device is placed in a Lithium-ion cell (18650, 21700, and pouch cells) to intentionally short circuit the cell on demand. Triggering occurs when the cell is heated to between 40 and 60 °C, which causes the cell to short circuit in a controlled environment.

The cell’s structure is preserved prior to triggering and overall cell performance is not impacted by the ISC pad implementation.

The device allows the user to identify and study any safety issues with a cell or battery pack design. It can be used as a valuable research tool for research institutes, battery manufacturers, or OEMs who wish to improve both the performance and safety of their Li-ion battery cells.

The internal short circuit (ISC) trigger cell, utilizing proprietary technology exclusively licensed to KULR by the National Renewable Energy Laboratory (NREL) and NASA, is the ideal testing tool for your batteries and battery packs. Through its use, failure conditions of a cell are mimicked in order to identify and study the failure modes and safety issues that could arise within Li-ion batteries and battery packs.

Historically, nail penetration tests have been used to short circuit Li-ion cells. This is widely considered an archaic testing method that has a number of drawbacks. NREL and NASA noted a need for change in these testing methods and subsequently developed a new, more controlled and reliable testing method for lithium-ion batteries. The cell comes in 18650 and 21700 cell builds.

This is a valuable engineering tool for research institutes, battery manufacturers, and OEMs looking to improve the performance and safety of Li-ion batteries and battery packs.
