As part of the production of Li-ion batteries, the CEA wishes to acquire equipment for laser cutting of metallic materials.

As part of the production of Li-ion batteries, the CEA wishes to acquire equipment for laser cutting of metallic materials. Indeed, the CEA designs and manufactures custom batteries according to customer specifications. A battery is made up of unit cells (also called accumulator). Each cell placed in a series or parallel configuration makes up a module. Each module placed in a series or parallel configuration makes up a battery pack. In order to achieve a modular electrical and mechanical architecture using lithium-ion or other accumulators, it is relevant to be able to link them together by an interconnection method allowing easy assembly. These electrical interconnections, also called foils, are then soldered onto the cells. An electronic card is generally arranged on one of the sides of the battery and will be connected to the cells by these same foils.

The equipment that the CEA wishes to acquire must therefore be capable of cutting all the configurations described in the technical specifications, in particular for cutting materials such as aluminum, steels (stainless steel, hilumin, etc.), nickel, CLAD and copper. The contract may include the following options:

- option 1 - optional: laser welding functionality;

- option 1a - optional: equipment security system.
