With the e.quikk technology for connecting the individual battery cells to form a battery system, we are able to manufacture sustainable energy storage systems. Each individual battery cell can be assembled and disassembled without any damage because no welding is required in the so-called "packaging" of the battery packs. Due to this innovation, each individual cell can be recycled or used in a 2nd life application and the components of the battery can be reused. Typical (1st Life) applications are microgrids, charging infrastructure, grid smoothing and peak shaving.
