Ultra High Precision Coulometry

Ultra High Precision Coulometry relies on:

  1. accurate high precision current measurement
  2. precision voltage measurement
  3. accurate and stable time base

Having these three core capabilities allows for precise measurements of cell capacity, cycling losses and hence changes in the cell performance over the first few cycles.
