A joint venture between Johnson Controls and Saft Advanced Power Solutions is developing lithium-ion batteries for hybrids and electric vehicles. General Motors tapped the technology for potential use in its Saturn Vue Green Line plug-in hybrid SUV. Lithium-ion technology offers advantages in packaging, energy storage and energy-delivery performance compared to the NiMH batteries used in hybrids today. The U.S. Advanced Battery Consortium is supporting the project, predicting the extended range that comes with longer battery life will enhance the attraction of hybrids.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
