Customcells® develops application-specific cell prototypes

In addition to the conventional shapes, the shape of our lithium batteries gives you great freedom of choice. For example, ring-shaped, angular, curved or polygonal lithium batteries are no problem for CUSTOMCELLS®. For example, a tubular compartment with pentagonal cells can be used more efficiently. We produce lithium batteries and energy storage solutions for you according to your shape requirements.

We configure the cathode, anode and separator films specifically for you to produce lithium batteries that meet your requirements in terms of geometry, capacity, cycle resistance, safety features, environmental resistance such as pressure or temperature resistance and power/energy density. The electrodes used are made of the latest generation of materials developed by CUSTOMCELLS® itself and manufactured on its own  coating systems.

We can offer you optimal solutions for low and high temperature applications. We implement and adapt modern electrolyte systems so that the energy storage solution meets your application requirements. Customer-specific requirements in terms of energy and power density, safety criteria, voltages and ecology can be met by the right choice of storage materials. Thanks to the CUSTOMCELLS® modular system, we have access to state-of-the-art active materials.

We select the right technology for your requirements. Depending on the application, we use laminating or stacking technology, ceramic, nonwoven or polymer separators and the specific electrochemical configuration to achieve maximum performance benefits. Shock and vibration resistance: Due to the special cell construction technology, CUSTOMCELLS® lithium batteries are characterized by high shock and vibration resistance and can also be manufactured with flexural strength in individual cases.

Active materials, electrolytes, additives, cell design and configuration enable us to largely optimize intrinsic safety at the cell level. This means that CUSTOMCELLS® is able to manufacture lithium batteries that pass penetration and short-circuit tests where standard solutions fail. We offer you safety-optimized energy storage solutions for your applications. The batteries manufactured by CUSTOMCELLS® are adapted to the environmental requirements of the respective application so that they are highly resistant to cold and heat. We use special processes to ensure maximum compressive strength (overpressure and underpressure) and shock resistance. Other special properties - such as magnetic field suppression - are possible in battery module construction.

Due to the surface loading, stacking and geometric configuration of the individual cell elements, the cell capacity between 0.01 and ~100 Ah per cell can be configured very freely. Energy and power density are optimally matched to your application. CUSTOMCELLS® provides the right solution: Whether long-term energy supply or high-performance energy storage with large discharge currents.

CUSTOMCELLS® energy storage devices offer optimum integration: We determine the position, shape, position, material, cross-section and connection technology of the electrical conductors of the battery or the connections of the battery module according to your product requirements. This enables us to ensure an optimum, loss-free and durable connection of the conductors and encapsulation of the cells, even under extreme operating conditions.

Specifications for cycle life and calendar aging are major challenges for lithium batteries, especially in terms of economy. When it comes to balancing energy density and stability, CUSTOMCELLS® has decades of experience in battery construction and benefits from a successful modular system that meets special requirements and produces extremely stable battery systems. According to your specifications for the energy storage solution, an exceptionally high number of cycles can be achieved by selecting the cell chemistry as well as the charging and discharging parameters. Under optimal conditions, compact prototype cells have already achieved more than 5,000 full cycles.

Customer requests for application-specific energy storage solutions from CUSTOMCELLS® have paved the way for special requirements. Our patented processes and flexible manufacturing enable us to build vacuum-tight cells, cells for high-pressure applications (tested up to a hydrostatic pressure of 500 bar) and non-magnetic cells.
