About this technology

Overview

Innovators at NASA Johnson Space Center developed a technique to test thermal management systems of lithium-ion (Li-ion) batteries called Small Format fractional Thermal Runaway Calorimetry (S-FTRC) utilizing unique testing hardware. This technique provides enhanced characterization of Li-ion cell thermal runaway energy release. The S-FTRC as hardware, is designed to accommodate a variety of Li-ion cell formats by providing universal interface for interchangeable cell chambers. A new cell chamber format has been designed to enable S-FTRC experiments with Li-ion pouch cells. Unlike cylindrical cells, pouch cells require uniform compression on either side of the cell and the ability for the cell to be unconstrained along the seams to ensure that the cell can vent in any direction when a thermal runaway condition is induced.
