- New Rheo-Impedance Spectroscopy (Rheo-IS) accessory enables
battery scientists to better assess electrode slurry composition
quality under real-world and process-relevant conditions.
- The Rheo-IS accessory for TA Instruments Discovery™ Hybrid
Rheometers employs a unique, patent-pending design that is
friction-free, allowing access to the full range of rheological and
electrical measurements.
- Delivers an easy-to-use, complete integration of measurement
controls and data analysis in a single software platform.
ORLANDO, Fla., March 13, 2024 /PRNewswire/ -- International
Battery Seminar -- Waters Corporation (NYSE:WAT) announced a
new accessory for its TA Instruments Discovery Hybrid Rheometers
(HR) designed to enable simultaneous electrical impedance and
rheological measurements, a critical capability for scientists
working on new battery formulations.
"Battery innovators that are focused on optimizing performance
and scale-up require sensitive tools to characterize electrode
slurry composition and ensure quality," said Jianqing Bennett, Senior Vice President of the
TA Instruments™ Division at Waters Corporation. "With the Rheo-IS
accessory, we now offer uncompromised rheometric sensitivity with a
full range of impedance measurements for slurry formulation
analysis in one versatile, easy-to-use platform – the Discovery
Hybrid Rheometer."
When used with Discovery HR, the Rheo-IS accessory enables
battery scientists to evaluate the conductive structure within
electrode slurries using impedance spectroscopy measurements under
real-world and process-relevant conditions. This includes
characterizing changes in particle distribution that mimic the
effects of mixing, storage, and coating processes. This can
accelerate electrode material development and lead to more
efficient battery production.
"TA Instruments Rheo-IS accessory provides our research program
with the ability to gain a new scientific understanding of
electrically and ionically conductive soft materials," said
Jeff Richards, assistant professor
of chemical and biological engineering at Northwestern University. "The integrated workflow
for automating complex rheological and electrical protocols and the
tight hardware and software integration makes measurements routine
and results in higher throughput and improved data quality."
Current rheology solutions rely on performance-limiting
mechanical contacts to deliver impedance measurements, which
compromise sensitivity and restrict accessible data and insights.
The Rheo-IS accessory avoids these limitations with its unique
patent-pending technology – a design that enables the Discovery
HR's full range of torque sensitivity for precision rheological
measurements, coupled with impedance measurements up to 8 MHz
frequency.
The Rheo-IS accessory offers an easy-to-use experience, with
installation completed in less than 5 minutes and complete
integration of measurement controls and data analysis in TA
Instruments TRIOS™ software. This addition expands the Discovery
HR's versatility for battery materials, offering rheological
measurements of slurry flow behavior, powder rheology to support
dry electrode coatings, and now simultaneous electrical impedance
measurements of slurries, all readily available on a single
platform. The Rheo-IS accessory is now orderable worldwide from
Waters TA Instruments.
