The Cellforce Group is committed to an environmentally responsible approach and to the sustainable use of resources. This applies both to the development of the site and to all the company’s business activities. In the long term, the entire region will benefit – through local investment, and through the jobs at a wide range of levels that will be created. Its new headquarters will also mean the Cellforce Group will become a local taxpayer, actively contributing to the prosperity of the region.
Construction and operation of the new Cellforce Group building comply with strict sustainability standards. Efforts include extensive roof greening and the installation of solar panels at suitable points.
The Cellforce Group is planning on an annual water consumption of around 30,000 cubic meters, which is very little for an industrial facility of this kind.
Process water will be recovered as far as possible and recirculated in the system.
The very low water consumption for this type of production site means that Cellforce Group operations will never affect water management for any neighboring businesses.
Our industry and recycling partner BASF will recycle all production and research waste generated and return it to the product cycle. Any cathode active material (CAM) and binder material will therefore undergo green and professional recycling.
The Cellforce Group is also committed to minimizing logistics traffic and encourages its partner companies to optimize their sustainability standards. Traffic optimization is being factored into building plans for the new headquarters to reduce the impact on the local transport network as far as possible.
Battery cell technology
Battery cells are at the heart of future mobility – and above all e-mobility. Nothing works without them. Batteries are already the main source of energy in countless mobility solutions and concepts. The Cellforce Group will take battery cell energy density, performance, and fast-charging capability to a whole new level – and thereby make a major contribution to improving the attractiveness of e-mobility.
The Cellforce Group is re-establishing its battery cell research and development expertise in Germany, for the competition is already way ahead. That is why the Cellforce Group works every day on perfecting this special technology.
But how does a battery cell actually work?
The Cellforce Group develops and produces lithium-ion cells, which can be used in electric vehicles, for example. Other applications are also possible.
A battery cell in an e-vehicle acts first and foremost as a mobile electricity storage device. This storage device converts chemical energy into electrical energy. That is why it is so important to keep developing the cell chemistry of battery cells further, as this is the main factor in a battery cell’s size, weight, and efficiency. The Cellforce Group conducts research and development in this field with the long-term goal of taking cell chemistry to a completely new level.
Unlike conventional batteries such as those you might find in a flashlight, for example, the battery cells in an electric car can fulfil two functions at the same time: They can draw electricity from the grid and later provide that electricity as required – repeatedly, until the battery cell needs to be recharged.
One battery cell consists of a large number of different components. The battery cell is the smallest unit in an electric drivetrain and motor, but it is the most important component as it determines energy availability.
Most e-car batteries operate at voltages of between 400 and 800 V. Much more power is required than what you get with an ordinary 230-volt household socket.
But what makes the Cellforce Group battery cell so special?
Chemical composition and design are the key differentiating factor here. Silicon is the anode material in the chemistry of the new high-performance cells. This makes it possible to significantly increase power density compared to current options, and the battery can be more compact for the same energy content. The new chemistry also reduces the internal resistance of the battery. This allows it to absorb more energy during energy recovery while at the same time offering improved performance for fast charging. Another special feature of the Cellforce battery cell is that it can be used at higher temperatures.
