ACCURATE CHARGE COUNTING
High precision coulometry requires a very accurate measurement of the charge quantities that are charged and discharged to/from a battery. Differences between the values from charging and discharging reveal the degradation rates.
One of our objectives is an excellent long-term stability of the current measurements to keep the charge balances accurate for all kinds of aging experiments – may they last days, weeks, or even months.
SEPARATION OF SIDE REACTIONS
The long-term stable ampere-hour integration helps our customers to identify and separate anodic and cathodic side reactions inside the batteries. For example, side reactions after lithium plating can be identified and quantified.
The high resolution of our current and voltage measurements enable you to spot even smallest differences in the aging among different battery cells or different operating conditions, which allows rapid qualitative comparisons.
