Siemens is using automation technology to support the development of efficient production processes for large-scale batteries.
A research production plant is currently being built at the Center for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW), Germany. As of 2015, industrial companies working at the center will begin developing close-to-production processes and new materials for lithium-ion batteries.
Their objective is to increase the quality of the batteries and lower the costs. Siemens is equipping the plant with a SCADA (Supervisory Control and Data Acquisition) system to handle production data. Among other benefits, this will help to evaluate production tests quickly.
Lithium-ion batteries are a key technology for the storage of electricity from renewable sources and for the expansion of electromobility. Today, there are only modest production capacities for these batteries in Europe.
In general terms, the production of lithium-ion cells comprises three steps: the production of the electrodes, then the fitting of the cell, followed by the activation, testing, and packaging of the finished cell. Making the electrodes is a complex process all by itself: carbon powder is mixed into a paste for the anode, and the cathode material is made of lithium metal oxides.
The pastes are applied to a metal film, either continuously or in patterns. The coating is only a few tenths of a millimeter thick, and it must be accurate to within one to two thousandths of a millimeter. These films move through the system at up to 50 meters per minute. The finished electrode films are cut, rolled up, and fitted in the casing. After that, the cells are filled with electrolyte and sealed.
Siemens has considerable experience in drive-system and automation technologies for high-precision production processes. Researchers at the global Siemens R&D department Corporate Technology and experts of the Industry Sector have analyzed all the processes used in battery production and put together a portfolio of solutions. It covers everything from drive systems and controls for individual production machines to communications technology and the plant management center. It also includes SCADA systems that supply all production data in real time.
This is particularly useful for a research production line, because the results - such as quality data for various production or material variants - are available right away. Siemens will use its production-planning software Tecnomatix to generate a virtual model of the plant and thus optimize its efficiency even before it is built.
Energy-storage devices are an important next-generation technology for Germany - both for the automotive industry and for the continued expansion of renewable energies. The new plant is directed at precisely these markets. It is expected to produce 300 industrial-standard prismatic lithium cells per day, each with a capacity of more than 20 ampere-hours. Siemens and the ZSW have signed a partnership agreement for the construction of the research production plant.

OLED microdisplays in data glasses for improved human-machine interaction
22.09.2016 | Fraunhofer-Institut für Organische Elektronik, Elektronenstrahl- und Plasmatechnik FEP
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
