Web Story | 2025-07-07
The global energy transition has brought with it increased demand for batteries to hold electrical energy from renewable sources.
In 2024, driven in part by a 25% rise in electric vehicle (EV) sales worldwide, but also by the need to store energy generated from renewables, annual battery demand surpassed a new milestone of 1 terawatt-hour (TWh).¹
Conventional batteries – those used in mobile phones or EVs, for example – rely on minerals and elements including lithium, cobalt and nickel, the extraction of which has raised environmental concerns².
But German storage manufacturer CMBlu has taken a different approach to storage of energy produced by renewable sources such as wind and solar. It has developed ‘organic’ batteries which do not rely on rare earths, lithium or rapidly flammable substances for their composition.
In simple terms, its technology imitates carbon-based molecules from the human citric acid cycle. From that basis, CMBlu has developed high-performance energy storage molecules that are entirely organic.
Having established the scientific basis for its approach, CMBlu is now engaged in scaling up its manufacturing capacity to bring economies of scale and reduce the cost of its products.
Production of CMBlu’s SolidFlow batteries, at its new production center in Alzenau, near Frankfurt, is being supported by ABB, thanks to the integration of our robots into its manufacturing process.
A total of six IRB 5710, 5720 and 6700 ABB robots are used in the CMBlu Energy production line.
They are integral to the sophisticated production process, from the provision of the frame elements, to adding the electrode and membrane components for the welding systems, to the leak test and then handling the finished battery stack.
The production line has a modular design, meaning that it can be scaled up, down or adapted to meet new requirements, based on CMBlu’s order book.
ABB’s OmniCore robot controls have also been integrated into CMBlu’s production line. Their highly efficient power electronics and braking energy recovery inside the robot enable energy savings of up to 20 percent.
RobotStudio® simulation and programming software allows visualization of the production line, enabling opportunities for optimization.
