For research applications, it is necessary to erase the coating “black mass” from one side of the electrode to measure the other side without effects from the back side. This is commonly done with a scalpel. We developed a system with CARL, ISEA, Research Center Jülich to erase the coating of the electrodes without damaging or heating up the metal foil.

The laser electrode stripping will be performed inside the glove box to avoid chemical reactions of the electrode or electrolyte (post-mortem analysis) with oxygen or moisture.

A laser safety enclosure ensures that no harmful laser light can escape. Therefore, no laser safety goggles are necessary. The system is laser class 1. We also deliver laser safety certificates and CE declaration.

A glove box provides ventilation and HEPA filter systems filter the particles out of the argon and guide the clean argon back to the glove box. The argon does not need to be disposed of.

At an add-on, we also deliver laser sources that can cut the electrodes, de-oxidize the metal or structure the coating.

• 1064 nm decoating of battery electrodes from active material without damaging the copper or aluminum foil
• 532 nm cutting of aluminum and copper, de oxidizing and activation of metal foils
• 355 nm precise cutting of metal foils, opening of battery packs without mechanical stress

Every circle indicates an available laser with a fixed pulse duration.

Every line indicates a laser with a variable pulse duration with a range of pulse duration.

The pulse durations are selectable via computer and can be part of a receipt.
