Circu Li-ion
Circu Li-ion is a battery upcycling company headquartered in Luxembourg. It’s our ambition to accelerate the green revolution by maximising the value of each battery to enable a truly sustainable economic electrification. Battery demand is growing—and so is the need for sustainable solutions along the value chain. In 2021, we have embarked on our journey to enable a circular lifecycle for batteries in three steps: the dismantling of batteries into material pure subcomponents, individual cell diagnostic and reassembly into useful 2nd life applications - automated and at scale. We provide our technology to leading players in the space of micromobility, q-commerce & delivery, hardware manufacturing and recycling. Our Machine-as-a-Service solution offers the possibility to capture the true value of still functioning resources through upcycling instead of recycling, which currently destroys 100% of the batter pack - saving money and the planet (- 48% battery CO2 emissions compared to a traditional battery life cycle).
