BATTERY DYNAMICS - High Precision Coulometry Battery Testing

THE METHOD

High Precision Coulometry

BATTERY DYNAMICS develops innovative battery testers. We are using the method of high precision coulometry, which generates faster results and provides deeper insights into the degradation of the batteries during cycling. We develop this method further and our software helps to get the maximum outcome of every battery aging study.

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.

LONG-TERM STABILITY

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.

RAPID COMPARISONS

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.
