NETZSCH supports companies developing new battery materials as well as helping streamline process efficiency and quality control.

The Li ion battery market is expanding at 12% Compound Annual Growth Rate (CAGR) and will be >1200 Gigawatt-hours at a value greater than 75 Billion USD by 2025.

These statistics are driven by electric vehicles (to combat city pollution), energy storage (in combination with renewable energy to reduce greenhouse gases) and portable communication devices.

The majority of automotive companies are now investing in batteries and rushing to patent key next generation battery technology and battery management systems.

To present a clear perspective, one Gigawatt-hour of battery energy is enough to manufacture 10 million Tesla Model S cars. However, battery technology is still adapting.

The most recent Tesla Model S electric car claims to possess a range of 402 miles with just a single charge, and 15 minutes charging time can supply a range of 136 miles. Future battery technologies like solid-state or lithium-sulfur batteries have the potential to extend this range to well over 1000 miles with accelerated charging times.

NETZSCH Supports Your Breakthroughs and Scientific Leaps

Whether you are a battery component manufacturer seeking out enhanced process efficiency and improved quality control, or a researcher attempting to establish the performance parameters of state-of-the-art battery materials, NETZSCH’s solutions will deliver advanced levels of insight and control for the production of superior-quality batteries.

NETZSCH Analyzing & Testing leverages 50 years of application experience, with wide-ranging innovative product lines and comprehensive service offerings. Thus, ensuring that the company’s solutions will not only meet each and every requirement but also exceed all expectations.

Controlling Battery Thermal Characteristics: Separator, Electrode and Electrode Coating

Like human body temperature, the operating temperature of a battery should be consistently monitored, protected and held at an optimal level. Appropriate battery thermal management guarantees an extended lifespan by ensuring the cells are maintained within a limited temperature range during charging, operation and storage.

Knowing how much heat can be dissipated by the cells demands a basic understanding of the heat transfer properties of the cell design. To evaluate these thermophysical properties, NETZSCH provides Laser/Light Flash Analysis systems (LFA) as well as Differential Scanning Calorimeters (DSC).

Each time a material is subjected to changes in temperature, it exhibits a variation in its dimension.

To anticipate the deformation and stresses in the separator in battery cells, it is vital to measure the behavior of expansion and shrinkage. This can be achieved through Thermomechanical Analysis (TMA), expressed by the coefficient of thermal expansion (CTE).

Processing Parameters: How to Apply Battery Slurry onto the Electrode

Blade coating or slot die coating are conventional ways of processing a battery slurry. During these processes, the slurry is subjected to mid-level shear rates for a brief period, accompanied by gravitational stresses acting in response to the slurry after the coating process.

This influences the leveling behavior at low shear rates and film uniformity. Rheology offers access to the flow properties of battery slurries.

Learn More About the Rheology of Battery Slurries in NETZSCH’s Webinar Event

In collaboration with Malvern Panalytical, NETZSCH’s analytical capacities are used in broad areas of the battery manufacturing process.

In a collaborative webinar event, both companies’ battery experts introduced pioneering analytical techniques to enhance the performance of your battery. The theories surrounding the established methods and instruments used for quality control and process efficiency were also explained.

Both sets of experts offer practical tips during live demonstrations in relation to the preparation of samples, performing measurements and evaluating the results with the respective software solutions.

NETZSCH’s Partnership with Malvern Panalytical

While NETZSCH Analyzing & Testing specializes in the thermal and rheological characteristics of battery components, Malvern Panalytical supplies elemental, morphological and structural analysis. 

With this partnership, customers can take advantage of a comprehensive range of solutions that supplement each other and rapidly determine the successful battery candidates. To discover more about these combined solutions, download the battery brochure.
