Encapsulation of cylindrical cells with polyurethane foam

The encapsulation of cells with polyurethane foam is a crucial strategy in battery design, with the aim of maximising energy storage in limited spaces.

As the number of cells within a battery increases, thermal management becomes a critical challenge.

The heat generated, especially in extreme conditions, can lead to failure events, compromising long-term performance.

Module Assembly Process

To meet this challenge, bicomponent materials such as silicones, silicone foams, epoxy resins, and polyurethane foams are used in the module assembly process.

Encapsulation of the cells with these special materials results in a significant reduction in thermal propagation, mechanical shock, and vibrations under conditions of daily use.

These applications not only help ensure the safety and stability of the battery, but also improve its long-term performance.

Proposed Solutions

The solutions we propose combine a mixer system (PR70, HFR, EFR, EVR) with a dosing valve which, depending on the needs, can have a dynamic mixer (Voltex) or not (MD2 valve).

This system is able to deliver a homogeneous mixture in continuous flow, ensuring uniformity and precision in the distribution of the encapsulation material.

The versatility of the system, which allows the dispensing speed and injection points to be adjusted, makes it highly adaptable to different configurations and designs.
