Lithium Battery Testing Solutions
From first formation to final grading — integrated testing workflows for lithium-ion cell factories producing NMC, LFP, LCO and next-generation chemistries.
Cell Quality Starts at Formation
Lithium battery testing is the backbone of cell quality. VoltTest builds integrated solutions that connect formation, grading, QC and safety testing into one traceable workflow — so every cell that leaves your factory carries verifiable quality data.
- ✓ Formation with precise CC/CV profiles and ≥90% energy recovery
- ✓ Grading by capacity, IR and self-discharge with automatic sorting
- ✓ Cycle life and rate capability testing for chemistry validation
- ✓ Safety certification testing per GB 31241, IEC 62133, UN 38.3
The Lithium Cell Test Workflow
Formation
First charge cycles with programmed CC/CV steps build the SEI layer and activate the cell.
Aging & Rest
Controlled rest and aging measurement detects self-discharge and micro-short defects.
Grading
Capacity, voltage and internal resistance sorting assigns cells to tight quality bins.
Safety & Ship
Sampled safety tests and final QC release cells for pack assembly or shipment.
