FOAM ENCAPSULATION OF CYLINDRICAL BATTERY CELLS

Designing a high performance battery module that remains safe under all failure conditions requires careful attention to thermal management. In addition to good thermal management practices, battery engineers are using interstitial encapsulation methods to provide even better protection.
To overcome this challenge in the module assembly process, two component materials such as silicone, silicone foam, epoxy, epoxy foam, and polyurethane foam are mixed and dispensed into the module to fill the spatial cavities between each cell. Encapsulating the cells with these specialty materials can prevent thermal runaway and thermal propagation, and reduce mechanical shock and vibration under normal use conditions. These enhancements ensure better safety, increased mechanical stability, and improved long-term battery performance.

La nostra soluzione è costituita dal sistema di gestione dell’erogazione PR70 e la valvola con mixer dinamico Voltex. Questo sistema eroga una miscela omogenea a flusso continuo garantendo uniformità e quantità di prodotto. La possibilità di gestire: velocità di erogazione e punti di iniezione, rendono questo sistema adattabile ad ogni design.

THERMAL MANAGEMENT BENEFITS FOR EV BATTERY

Electric vehicle batteries are continually evolving to last longer, provide better operational performance, and guarantee optimal safety. The battery requires reliable thermal management to meet these ever-increasing demands.
Each battery contains a Battery Management System (BMS) and a cooling circuit. While the BMS and cooling circuit control and manage the temperature inside the battery, the presence of thermal conductive pastes or gap fillers efficiently dissipates heat away from the battery to maintain the ideal operating temperature.
During the battery pack assembly, large volumes of Thermal interface materials (TIMs), also known as gap fillers, are dispensed between the cooling circuit and the battery modules/cells. TIMs contain highly abrasive fillers with thermally conductive characteristics, allowing heat to be dissipated away from the battery cells/module towards the cooling circuit.

SLURRY DISPENSE FOR ELECTRODE COATING

Growing demand for EV Battery manufacturing requires advanced solutions in the production of cylindrical Li-ion batteries – and slot die slurry dispense application is no different; it requires intelligent and high-performance equipment.
It is necessary to have accurate and repeatable pressure and flow through the dispense equipment to achieve the desired density, viscosity, and maximum homogeneity without breakup of particles. Over shearing the material during processing can impact finished electrodes and lead to future concerns such as cracking from processing or environmental conditions, ultimately causing degradation in the performance of the battery.
