There is virtually no limit to the items that can be produced with 3D-printing technology these days, and now researchers at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have used it to create a better magnet that happens to help protect the environment. The new 3D-printed magnet outperforms traditional magnets as well, making it even more desirable. Because the 3D-printing process involves zero waste, manufacturing the magnets helps conserve rare earth minerals, meaning more of them can stay in the ground. https://www.youtube.com/watch?v=-GJ2R9V93Eo The game-changing innovation created at ORNL  is an isotropic, near-net-shape, neodymium-iron-boron (NdFeB) permanent bonded magnet . Researchers working on the project report that the 3D-printed magnet has “comparable or better magnetic, mechanical, and microstructural properties” versus magnets with a similar composition that were created through conventional methods. The performance boost is just one of the benefits of this new technology, though.

In order to produce the magnets, composite pellets are melted, compounded, and extruded layer-by-layer into desired forms using the Big Area Additive Manufacturing (BAAM) machine, a special 3D-printer housed at the DOE’s Manufacturing Demonstration Facility at ORNL. Using 3D-printing to manufacture the magnets is a zero waste process, while conventional sintered magnet manufacturing can result in material waste up to 50 percent. The results of the innovation were recently published in the journal Scientific Reports. Via Phys.org Images via ORNL

All-Solid Lithium Sulfur Battery Stores Four Times as Much Energy as Lithium Ion Batteries

Comments Off on All-Solid Lithium Sulfur Battery Stores Four Times as Much Energy as Lithium Ion Batteries

Researchers at the DoE’s Oak Ridge National Laboratory (ORNL) have developed a lithium sulfur battery that is not only cheaper and safer than lithium ion batteries , but can store four times as much energy as its lithium ion counterparts. Used in small electronics and electric vehicles, lithium ion batteries are a standard for energy storage, but lithium sulfur batteries—which are already used in some solar aircraft —have the potential to succeed as an alternative with much higher energy density, and ORNL’s all-solid Li-S batteries are testing as safer and more durable than current Li-ion’s.
