Overview

The Reference 30k Booster for the Reference 3020 Potentiostat is an external hardware option which increases the current limit of the Reference 3020/3020AE to ± 30 Amps.  It features a class-leading bandwidth of 300 kHz, allowing for high-frequency EIS measurements and rapid pulsing experiments.  The Reference 3020 Potentiostat plus the Reference 30k Booster is an ideal system for the evaluation of new technologies for batteries, fuel cells, supercapacitors, electrolyzers, and critical mineral recovery studies. The compliance limits of the Reference 30k  pass through zero volts for supercapacitor work and hydrogen crossover studies. This system can accurately measure impedance values below 100 μΩ. 

The Reference 30k is not only limited to high current applications but has been uniquely designed to allow pass-through measurements. This means that you can use the 3 A, 300 mA, and 30 mA ranges of the Reference 3020/3020AE while still connected to the booster. Our systems are designed to pick the most appropriate range, giving you the highest resolution possible. 

Electrochemical Impedance Spectroscopy

The Reference 30K Booster is fully capable of performing electrochemical impedance spectroscopy.  The shorted lead curve is a measure of the limits of the instrument.  

Rapid Pulsing

The booster's impressive 300 kHz bandwidth also allows it to do rapid pulsing experiments for techniques for cell characterization.  As mentioned above, the system's response (including electrochemical cell) is dependent upon the instrument's internal resistances as well as the resistance of your cell.  Below is an example of a 200 μs 12 A pulse on a 200 mΩ cell.

// Overview

The Reference 30k™ Booster is ideal for higher current applications such as large format batteries, fuel cells, electrolyzers/electrolysis and critical mineral recovery studies. Ground isolation allows for operation in parallel with a power supply or electronic load or grounded cells.  The Reference 30K Booster attaches to a Reference 3020 Potentiostat or Reference 3020 Auxiliary Electrometer to bring the current limit up to ± 30 Amps with voltage/compliance limits of +20 and -2.5 V.  This high current device features impressive bandwidth allowing EIS measurements up to 300 kHz.

Safety

At these currents, safety is a must and we have incorporated several features to prevent damage to both the instrument and the user.  The system is protected against self-inflicted damage to the circuits, contains an emergency shut-off button, has a protective ground terminal and provides an insulating barricade to prevent accidental shorting across the terminals.
