AZL: Plastic-based multi-material solutions for cell-to-pack battery enclosures

The future of e-mobility will be determined in particular by safe battery enclosures. As batteries for electric vehicles become more performant, higher volumetric energy density plays a crucial role. If more energy is to be stored in less installation space, new material and design solutions are required. The development of suitable enclosures made of safe and highly robust lightweight materials is also required. This is a case for the Aachen Centre for Integrative Lightweight Production (AZL). A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

A project on cell-to-pack battery enclosures for battery-electric vehicles, which has been eagerly awaited in the industry, will start in October this year there.

The design of battery housings is crucial for safety, capacity, performance, and economics. The Cell-to-Pack project, which is starting now, will focus on developing concepts for structural components and for producing them based on a variety of materials and design approaches. The concepts will be compared in terms of performance, weight and production costs, creating new know-how for OEMs, producers and their suppliers throughout the battery vehicle value chain. Companies are now invited to participate in this new cross-industry project to develop battery enclosure concepts for the promising and trend-setting cell-to-pack technology.

The basis for the project is the lightweight engineering expertise of the AZL experts, which they have already demonstrated in previous projects for multi-material solutions for module-based battery housings. Together with 46 industry partners, including Audi, Asahi Kasei, Covestro, DSM, EconCore, Faurecia, Hutchinson, Johns Manville, Magna, Marelli and Teijin, 20 different multi-material concepts were optimized in terms of weight and cost and compared with a reference component made from aluminum. All production steps were modelled in detail to obtain reliable cost estimates for each variant. Result: depending on the concept, 20% weight or 36% cost savings potential could be identified by using multi-material composites compared to the established aluminum reference.

It is expected that the design concept of battery enclosures will develop in the direction of a more efficient layout. In this case, the cells are no longer combined in modules in additional production steps, but are integrated directly into the battery housing. The elimination of battery modules and the improved, weight-saving use of space will allow for higher packing density, reduced overall height and cost saving. In addition, various levels of structural integration of the battery housing into the body structure are expected. These new designs bring specific challenges, including ensuring protection of the battery cells from external damage and fire protection. In addition, different recyclability and repair requirements may significantly impact future designs. How the different material and structural options for future generations of battery enclosures for the cell-to-pack technology might look like and how they compare in terms of cost and environmental impact will be investigated in the new AZL project. In addition to the material and production concepts from the concept study for module-based battery enclosures, results from a currently ongoing benchmarking of different materials for the impact protection plate and a new method for determining mechanical properties during a fire test will also be incorporated.

The project will start on October 27, 2022 with a kick-off meeting of the consortium, interested companies can still apply for participation until then.

DSM to showcase armor solutions made with Dyneema® at Milipol Paris 2021

DSM, the inventor and manufacturer of Dyneema®, will be exhibiting at one of the leading events for homeland security and safety, Milipol Paris 2021, from October 19-22.

The performance characteristics of Dyneema® make it ideal for a variety of applications, including soft and hard armor ballistics to protect against today’s advanced and emerging threats. In addition, Dyneema® combines next-generation fiber technology and unidirectional engineering to deliver armor solutions with unmatched ballistic stopping power in a lightweight and flexible composite.

By implementing Dyneema®, body armor manufacturers are able to use less material in the development of their ballistic vests, plates and helmets. This leads to weight savings upwards of 30 percent when compared to competitive materials, without impacting ballistic performance. The lightweight construction of armor made with Dyneema® also mitigates injuries associated with the cumulative effects of daily armor use – while improving situational awareness, as well as cognitive and tactical performance.

While decreasing the load on the wearer, Dyneema® is simultaneously able to reduce the impact of material manufacturing on our planet. In line with DSM’s commitment to protect people and the environment they live in, we have developed the first-ever bio-based ultra-high molecular weight polyethylene fiber and unidirectional (UD) material. Bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE.

norda™: Flagship product with DSM’s bio-based Dyneema® fiber

Royal DSM, a global science-based company in Nutrition, Health and Sustainable Living, confirmed the introduction of the first seamless trail running shoe made with bio-based Dyneema® fiber by norda™, a Canadian shoe brand.

Designed for runners by runners, norda™ was founded under the mission to empower athletes to unlock their peak potential through innovation and cutting-edge technology. The brand’s flagship product, norda™001, utilizes bio-based Dyneema® fiber to enhance performance and sustainability in a lightweight construction.

The shoe upper is seamlessly constructed with Dyneema® fabric, which benefits from the intrinsic properties of Dyneema®, the world’s strongest fiber™. Dyneema® fiber is engineered at the molecular level to provide high strength, low weight, waterproof and breathable properties – fusing the technical performance of ultra-light materials with aesthetic design that does not sacrifice strength or durability.

In addition to the increased foot stability and wearer comfort of the upper, Dyneema® fibers are also used to increase abrasion resistance and stretch in the shoe laces – providing four times the level of strength when compared to standard lace materials like nylon and polyester.

“When we set out to create the norda™ 001, our mission was to design an ultra-strong and durable high performance trail running shoe, and do it as sustainably as possible,” states Willamina and Nick Martire, Co-Founders, norda™. “To achieve our goal, we had to look outside of the standard materials used by the footwear industry. We realized the properties of bio-based Dyneema® beat everything available today.”

In line with DSM’s commitment to protect people and the environment they live in, bio-based Dyneema® boasts the same exact performance as conventional Dyneema® with a carbon footprint that is 90 percent lower than generic HMPE. Sourced from renewable, bio-based feedstock, DSM’s latest advancement in fiber technology uses the mass balance approach to further reduce the reliance on fossil fuel based resources, while still contributing to a more circular economy.
