The laboratory is equipped in three 8-channel MACCOR® battery cyclers build up on portable carts with APC Smart-UPS power supplies that allow cycler transport around the ring without disturbing running battery cells. The carts also contain basic supplies such as alligator cables, banana cables, Velcro, cable ties, allen wrenches and Fluke Multimeter. Coin cells holders and AMPIX cells and holders are available by additional request. While all of our MACCOR® cyclers can be used for routine galvanostatic, PITT, GITT measurements, each cycler has unique configuration and capability. You can check common and unique specifications bellow.

Portable 8-channel MACCOR® battery cyclers (model 4300)
Standard system that provides the highest level of accuracy and time resolution. The simplified short guide for our users answering most common questions can be found here
- Each test channel is controlled independently of the other channels in the system.
- Step types include: Charge (Source Current), Discharge (Sink Current), Rest (Wait), Voltage Scan, Pulse – 10 ms standard.
- Steps can be user-programmed to operate in modes of constant (fixed) current, power, voltage, or resistance. Each test step can have up to 16 different end conditions.
- Tests can branch to any step in the test based on the step end criteria met.
- Step end conditions include but are not limited to: measured values (voltage, current, time, etc.), integrated values (energy, capacity, half-cycle data), and calculated values (ΔV/δt, ΔT/δt, first and second derivatives).
- Four levels of loop nesting are available in each test.
- Test procedures can be called as a subroutine in another test yielding virtually limitless step lengths.
- Similarly rated test channels can be combined in parallel in groups of 2, 4, or 8 to yield higher-current-rated channels when needed.

Single Channel CHInstruments® 660e Potentiostat
General-purpose electrochemical measurement instrument with a very wide dynamic range of experimental time scales. The potentiostat/galvanostat uses a 4-electrode configuration, allowing liquid/liquid interface measurements and eliminating the effect of contact resistance of connectors and relays for high-current measurements.
The data acquisition system allows an external input signal (such as spectroscopic) to be recorded simultaneously during an electrochemical measurement. The instrument supports a wide variety of electrochemical techniques and is available with integrated simulation and fitting software functions for both impedance and cyclic voltammetry, providing powerful tools for mechanistic studies and trace analysis.
