FASTER RESULTS

Our battery testers typically speed up battery aging experiments by a factor of 5-10, helping to reduce testing capacities and cost.

NEW INSIGHTS

Our software helps you to identify aging side reactions at the positive and negative electrode without cell openings.

MAXIMUM PRECISION

High-class measurement electronics maintain outstanding precision also throughout longer testing periods.

Solutions for Better Battery Aging Studies

Our mission is to speed up the work of battery system engineers and battery material researchers.
BATTERY DYNAMICS testers provide more accurate results than standard battery testers and help to reduce the time and cost for the search of new battery materials and the development of new battery systems with lifetime-optimized operating strategies.

FAST CHARGING

Accelerate the development of new fast charging protocols for electric vehicles: Our high precision coulometry battery testers help you to determine the maximum charging rate for various operating conditions to avoid lithium plating and side reactions at the negative electrode, which deteriorate battery life.

NEXT GENERATION BATTERY MATERIALS

Batteries with higher energy densities require new battery materials, which provide higher capacities and higher battery voltages.
High precision coulometry allows you to test many electrode material and electrolyte varations within a short period of time to identify innovative solutions for next-generation batteries.

PARAMETERS FOR BATTERY MODELS

Battery models and numerical simulation speed up the development of new battery systems.
The BATTERY DYNAMICS testers help you to facilitate and speed up the parameterization process of battery aging models.
Lifetime projections with higher reliability can already be performed at an early stage of the developoment process.

LOW-TEMPERATURE OPERATION

Temperatures below 0°C reduce the performance and cycle life of lithium-ion batteries considerably.
With our high precision coulometry testers, you can identify the degradation mechanisms that stress your battery cells and develop optimized thermal management strategies that prevent premature failures.

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.

Our Portfolio

BATTERY DYNAMICS provides testers for battery testing labs, which are optimized for different sizes of battery cells.

Our deep understanding of lithium-ion battery degradation and our hands-on experience in battery testing help you to reduce your testing efforts, minimize uncertainties in lifetime estimations, and shorten your time to market.
