Debonding coating
Let’s talk about your projectSpray debonding coating solution with a bell
Debonding coating rotary bell sprayer delivering ultra high transfer efficiency
Description
Reparability or Recyclability ? For both reasons, the access to the battery cells to remove defective ones becomes a must.
Material suppliers are proposing debonding coatings to remove them without damaging the cells and their environnement. The latest heating solution seems promising, even if the challenge to heat locally remains to set properly. Under the Thermal Conductive Adhesive (TCA), the debonding layer is sprayed either on cooling plate at supplier factory, or on the plates fixed inside the pack before dispensing the TCA.
For the debonding layer, we have the efficient and fast robotic sprayers to reach eveness thickness, and access to bottom of battery packs : airspray gun, rotary bell sprayer or even the printing technology for zero overspray!
Contact us, and let's study your project to organize validation process to the industrial robust solution for your batteries.
Main benefits
Perfect uniform coating
Access to cooling plate inside the battery pack
Range of robotic spraying technology

Debonding coating FAQ
Let's get in touch-
Why a debonding layer in a battery pack?
The cost of battery pack represents over 40% of the EV car. During life of an EV car, some cells are damaged and not performing as it used to. The BMS is able to identify which cells are defective and isolate them, but charge capacity is reduced.
Reparability of the pack requires to open and remove the defective cells, which are glued inside.
By activating a debonding layer under the adhesive, the cells can be removed easily. -
What are the activating technologies possible for debonding layers ?
There are six way to activate a debonding layer : heat, electrical, UV light, ultra sound, chemical, magnetic. Each have drawback, especially in a very expensive and sensitive battery pack!
-
Which debonding technology is the most promising?
Heating to 80°C seems the most promising technology, maybe less expensive that electrical activation of the debonding layer which is much precise that heat diffusion.
