ADDEV Materials


In addition to converting techniques, Addev Materials provides additional services. These services include both innovation and engineering aspects as well as production and logistics.

One of Addev Materials’ specialties is the development of multi-materials combining complex properties. This allows it to meet all kinds of specifications for customers from all industries. Below are three examples

No material is perfect. However, by combining assembly, surface treatment and coating techniques, it is possible to combine the properties of several materials by forming multilayers. Thanks to these three families of processes there are almost no limits to the creation of custom-made materials.

The properties of film materials can vary according to their nature or chemistry. These properties are sometimes incompatible with an application and the selection of the right material is often a matter of compromise. However, combinations can be made thanks to functionalization.

Integrating electrical insulators into a battery can take time. ADDEV Materials has the expertise to reduce this implementation time and has developed a series of made-to-measure solutions for manufacturers of electrical vehicle batteries.

Electric vehicle battery design is influenced by space constraints. As well as providing electrical insulation, these materials therefore need to be as compact as possible to facilitate their integration. Here’s an overview of the insulation materials most frequently used in the design of electric vehicle batteries.

The cells and modules that compose an electric vehicle battery pack should be protected from electrical discharges. This protection is most often guaranteed by insulation materials in the form of films, foams or liquids. So what are the key criteria when selecting an electrical insulator? Here are some insights into what to look for.

Electric vehicles need vast quantities of energy in order to function. This energy is stored in high-voltage batteries that must have perfect electrical insulation, hence the need for suitable materials to be used.

Insulating adhesives, foams, films or thermal pads are just a few examples of products that can be used to manage thermal constraints in electric vehicle batteries. As a material converter, ADDEV Materials is able to provide tailored solutions for cutting and functionalizing base materials.

Whether in use or stopped, a battery should be protected against external variations in temperature. While batteries don’t like heat, they are even less tolerant of the cold. Worse still, sub-zero temperatures can render them unusable if no action is taken to prevent this. Find out how to protect an electric vehicle battery from the external environment

The core temperature of the cells of a Li-ion type electric battery in use should not exceed 80 to 90°C. However, these moderate values do not come about by chance: they are the result of thermal management of batteries, reconciling heat dissipation with power control. Specifically, what methods are used to dissipate this heat?

In electric vehicles, thermal management makes it possible to not only improve battery power and longevity, but also to reduce the size of electric engines. Temperature is thus the main parameter that needs to be controlled in a battery, hence the need to use suitable electrical and thermal insulation materials. Here is a summary of the main issues related to thermal management.

When they leave the manufacturer, electrical insulators are available in roll or sheet form. ADDEV Materials places its expertise at the service of its clients by offering the functionalization and cutting of these insulators, to correspond to the most demanding of client specifications.

Aside from guaranteeing a dielectric function, an insulation material should be able to withstand the temperatures of the usage conditions for the equipment to be protected. This capability is characterized by the thermal class and should be defined in the specifications.

No insulation material has an unlimited lifespan and dielectric properties can degrade over time. While the deterioration factors of these insulators may vary, the consequences are always the same: a breakdown in the equipment it was supposed to protect. It is therefore vital to always choose the material best suited to the specifications.

Present in all industrial sectors, electrical insulators are vital components for the protection of equipment and people. Insulators can be found in hundreds of combinations of forms, substances and assemblies, whose applications can vary dramatically. Here is a quick overview of these materials.
