Materials for batteries: Tailor-made solutions for safe and efficient electromobility

The rapid development of electromobility not only brings ecological advantages, but also new challenges for the batteries used. The thermal stability and safety of lithium-ion batteries in particular play a crucial role. With its product range for electromobility, Dr. Dietrich Müller GmbH offers tailor-made solutions that optimally protect batteries in cars, trucks and even in aerospace and aerospace and maximize their performance.

Heat under control: Heatshields for extreme temperatures

One of the biggest risks for lithium-ion batteries is heat generation. In the worst case, this can lead to thermal runaway, where the battery heats up uncontrollably and catches fire. To prevent this, Dr. Dietrich Müller GmbH uses high-performance heat shields. These are made of special materials that can withstand temperatures of over 1000 °C for at least 15 minutes.

The advantages of Dr. Dietrich Müller’s Heatshields go far beyond pure heat protection:

• Proven safer: The Heatshields have been extensively tested and are proven to provide protection against thermal propagation, preventing a heat problem in one cell from spreading to neighboring cells and causing a domino effect.
• Long-lasting functionality: The materials used retain their shape and functionality even when exposed to high heat. This extends the service life of the entire battery system.

Precise spacing: Cell Spacer for optimal performance

Within a battery, the individual cells are not simply arranged next to each other, but are separated from each other by spacers, so-called cell spacers. These fulfill several important tasks:

• Optimal heat dissipation: The Cell Spacers from Dr. Dietrich Müller are characterized by high thermal resistance and ultra-low thermal conductivity. This effectively dissipates the heat generated in the individual cells and achieves an even temperature distribution within the battery.
• Improved cell capacity: The adjustable compression behavior of the cell spacers allows the pressure on the individual cells to be optimally adjusted. This leads to maximum cell capacity over the entire service life of the battery.
• Delaying heat propagation: In the event of a heat problem, the cell spacers act as a barrier and delay or prevent thermal spread between the cells. This limits damage in an emergency and increases safety.

Targeted pressure relief: Burst membranes for safe cell degradation

Another safety feature in Dr. Dietrich Müller's product range is burst membranes. These membranes serve as predetermined breaking points in the battery. If the pressure in a cell increases too much due to heat development or other factors, the burst membrane breaks open in a controlled manner. This reduces the pressure suddenly and prevents the risk of an explosion.

The Burst Membranes from Dr. Dietrich Müller offer the following advantages:

• Precise pressure relief: The membranes are designed to burst at a defined pressure value. This prevents the cell from bursting uncontrollably and protects neighboring cells from damage.
• High temperature resistance: Even when exposed to heat, the burst membranes retain their functionality and guarantee reliable pressure relief.
• Lightweight construction: The materials used are particularly light, which minimizes the overall weight of the battery.

High-voltage insulation: Busbar insulation for reliable current conduction

The power distribution in a battery takes place via so-called busbars. In order to prevent short circuits and electrical leaks, these must be reliably insulated. Dr. Dietrich Müller offers busbar insulations for this purpose, which were specially developed for the requirements of electromobility.

The busbar insulations are characterized by the following properties:

• High voltage resistant: The insulating materials are designed for use in high-voltage systems and guarantee safe current conduction even at high voltages.
• High CTI values: The CTI value (Comparative Tracking Index) indicates the tracking resistance of a material. The Busbar Insulations from Dr. Dietrich Müller have particularly high CTI values ​​and thus offer optimal protection against tracking currents that can lead to insulation failure.
• Electrical insulation under all conditions: The insulating materials function reliably not only in normal operation, but also in the event of a thermal

Protection and stability: Module covers for optimal housing applications

The module housing forms the end of a battery. In order to protect the sensitive battery cells from external influences and at the same time ensure optimal heat dissipation, Dr. Dietrich Müller GmbH offers special module covers. These covers are made from multifunctional and multi-layered materials that offer the following advantages:

• Proven protection: The module covers have been extensively tested for their protective effect against shocks, vibrations and environmental influences. This means the battery system is optimally protected against mechanical damage and corrosion.
• Proven thermal and mechanical stability: The materials used are characterized by high thermal and mechanical stability. This ensures even heat distribution and protects the battery cells from deformation.
• Multifunctional design: In addition to their protective function, the module covers can also perform additional tasks, such as the integration of cooling channels or the accommodation of sensors.
