Dynexus Technology, a leader in battery sensing solutions and
data-driven battery intelligence, is pleased to announce
independent validation of its iRIS® sensor for early detection of
thermal runaway in Lithium-ion batteries. “We are both excited and
pleased with the performance of the iRIS in the published Sandia
National Laboratory study,” said Jon Christophersen, Dynexus
Technology’s CTO.
According to the paper published in February, “In scenarios of
excessive temperature leading to failure of single cells, the use
of rapid EIS showed a distinct advantage over gas sensors for early
detection. Specifically, rapid EIS was able to identify a
malfunctioning cell with a significantly larger warning time (>3
times longer), thereby allowing for earlier response times to
potentially intervene and mitigate further damage.” “The gas
sensors and rapid EIS provided a failure marker at significantly
different temperatures, 152 degrees C and 99 degrees C,
respectively. Ideally, the failure marker should be identified at
temperatures below 100 degrees C.” (Loraine Torres-Castro et al

Initially developed at the Idaho National Laboratories, in
collaboration with Montana Tech, Dynexus Technology’s iRIS® can
actively monitor a battery, or a string of batteries, to determine
their State of Charge, State of Health, and most importantly in
this context, their State of Stability. The award winning inline
Rapid Impedance Spectroscopy (iRIS®) sensors generate near
real-time, rich, frequency-based battery data that provide
information about the state of a battery's physico-chemistry.
In its conclusion, the paper states, “An ideal BMS would
incorporate rapid EIS, in combination with traditionally collected
data points (i.e., voltage and temperature), to achieve detection
of failure markers prior to venting.” (Loraine Torres-Castro et al

“Ultimately, iRIS-class devices will be incorporated into Active
Energy Management Systems™, the next-generation solution beyond
today’s battery management systems (BMS) with active energy
management capabilities in both land-based and airborne
battery-electric platforms,” said Ty Carlson, Chief Strategy
Officer at Dynexus.
With growing concerns regarding lithium-ion battery fires,
active monitoring of the state of stability of battery systems is
critical to avoid loss of life and property. “Dynexus is
commercializing the only active energy management system with this
capability,” said David Sorum, CEO of Dynexus Technology.
