SEALING WITH SIKA. Good sealing is integral for optimum performance and safety in the battery environment, whether for mobility applications or stationary energy storage. Finding the balance between securing the battery housing along with systems to allow for easy access are an important contributor to the circularity required in battery
This new requirement for battery systems is owed to the increasing energy density both on cell and system level. The chemically stored energy is more and more "compressed". In case of a severe cell malfunction (the so-called "thermal runaway"), it becomes more and more difficult to protect the neighboring cells from the released heat. For this reason,
The principle of operation and construction of Li-polymer batteries are identical to those of Li-ion batteries. These batteries operate on the principle of deintercalation and intercalation of lithium ions from positive electrode materials to negative electrode materials. Fig. 1. Trendsetters for mass use of Li-battery technology: Siemens S4
The battery management systems for lithium ion batteries require condition monitoring signals— such as temperature and voltage—to pass through the sealed battery container. That''s where our CircuitSeal™ technology comes in. CircuitSeal uses epoxies and proprietary manufacturing techniques to hermetically seal and

NiMH batteries are similar to lead-acid batteries but are more efficient and have a higher energy density. Li-ion batteries are the most advanced type of car battery and are known for their high energy density and long lifespan. What Is Sulfation and How It Affects Batteries. Sulfation is a common problem that affects all types of car batteries

Sealing is an effective dispensing method for protecting components from external influences by creating a barrier.
A process was developed by bdtronic in which the highly abrasive gap filler is injected at low pressure into the housing of a battery module so as not to damage the sensitive pouch cells. The gap between the battery and the housing base is filled completely and without air bubbles. Housing bonding and sealing
The battery modules generate energy in the form of heat during operation. This is dissipated by applying thermally conductive materials between the battery module and the aluminium heat sink to prevent overheating. Thermally conductive liquid gap fillers are designed for automatic dispensing in high-volume production.
Effective heat dissipation with gap filler application or injection The battery modules generate energy in the form of heat during operation. This is dissipated by applying thermally conductive materials between the battery module and the aluminium heat sink to prevent overheating.
Since battery cells cannot be potted under vacuum, it is important to have a dispensing process that is optimally developed for the component and the potting material used. Ideally, this is determined in advance in lab trials at the Technology Center before it is applied to the series production machine.
To achieve the best possible adhesion with long-term stability, the battery cells are pretreated with plasma to activate and clean the surface before the adhesive is applied. Treating plastic and metal surfaces with plasma improves their ability to bond to an adhesive in several ways.
