NDJ-5S Digital Display Viscometer For Battery Slurry

Overview

The NDJ-5S Digital Display Viscometer for Battery Slurry is a benchtop rotational viscometer designed for routine viscosity measurement of electrode slurries, pastes and related process fluids used in battery research and manufacturing. It works by rotating a spindle in the sample at a defined speed and measuring the torque generated by viscous resistance. The instrument then converts this response into a viscosity reading displayed directly on the screen, making it suitable for fast formulation checks and process consistency monitoring in battery laboratories.

Typical Applications

This digital viscometer is well suited to lithium-ion and sodium-ion battery slurry development, including cathode and anode formulations, conductive additive dispersions, binder-containing suspensions, coating slurry optimisation and batch-to-batch quality control. It is especially useful during slurry preparation before coating, where viscosity strongly influences mixing behaviour, coatability, levelling and electrode uniformity.

Why Choose This System from ScienceGears

For researchers and engineers, this model offers a practical balance of simplicity, speed and relevant viscosity range for battery slurry work. In practice, it is best suited to routine QC, formulation comparison and process troubleshooting rather than advanced rheological modelling. ScienceGears supports Australian and New Zealand customers with application-focused guidance and can help integrate this instrument with related battery R&D tools such as mixers, coaters, battery cyclers, electrochemical cells and potentiostats for a more complete lab workflow.
