Better Coin Cells. Better Data. Better Battery Decisions.
Send us your one-sided coated electrode material. We prepare it, build standardized CR2032 lithium half-cells, perform controlled electrochemical testing, and return clear, reproducible performance data.
Controlled construction
Standardized hardware and assembly keep the electrode material as the primary experimental variable.
First-cycle efficiency
Demonstrated in graphite anode half-cell development testing.
Reliable material decisions require reliable test cells.
Small differences in electrode preparation, lithium condition, hardware, alignment, pressure, and assembly technique can create meaningful variation in half-cell data.
ON Cell Technologies reduces these uncontrolled variables through an optimized, standardized construction process so researchers can focus on the behavior of the material being tested.

From coated electrode sheet to usable data.
Each project begins with three or more replicate cells to evaluate material performance and cell-to-cell reproducibility.
Prepare
Inspect, punch to 15 mm, individually weigh, and dry one-sided coated electrodes.
Assemble
Build standardized CR2032 lithium half-cells using controlled components and hardware.
Test
Rest, monitor, cycle, and evaluate cells using the agreed electrochemical protocol.
Deliver
Receive individual-cell results, replicate comparisons, processed graphs, and raw cycler files.
Data you can evaluate with confidence.
Representative QCG-X and FSN1 graphite tests demonstrate high first-cycle efficiency, strong reversible capacity, and closely overlapping cycling profiles.
Performance depends on the electrode material, sample quality, and agreed test conditions.
A focused service for coated electrode materials.
ON Cell Technologies accepts one-sided coated electrode sheets for lithium half-cell evaluation.
Graphite & anode materials
Half-cell testing for coated anodes, including graphite-based materials and suitable alternative anode chemistries.
Cathode materials
Suitable one-sided coated cathodes can be evaluated using project-specific voltage windows and cycling conditions.
Custom electrode protocols
Additional replicates, benchmark comparisons, custom cycling rates, voltage windows, and extended cycling are available by quote.
A process built through hundreds of construction trials.
ON Cell Technologies was founded by Oliver Nimon, a mechanical engineering student at the University of Tennessee. Focused research into lithium half-cell construction evaluated hundreds of combinations of hardware configurations, materials, and assembly techniques.
This work led to the optimized process that forms the technical foundation of ON Cell Technologies. Initial testing is conducted in collaboration with Coulometrics in Chattanooga, Tennessee.
