Lithium-ion batteries are used in different areas – from mobile phones and laptops to cardiac pacemakers and electric vehicles. Currently, scientists are trying to increase battery power while reducing its size. The team of researchers from Russia and China in collaboration with an industrial partner managed to increase the battery’s energy capacity by 15%. The…
New Technology For Producing Porous Aluminum
A new technology of producing an unsinkable aluminum alloy was developed at Peter the Great St. Petersburg Polytechnic University (SPbPU). Porosity is produced by the addition of foaming gas into liquid aluminum during re-melting. The porous materials can increase stiffness and sound and heat insulating proprieties, according to the SPbPU’s Media-center. “A high porosity level…
New Application of the Selective Laser Melting Method
Scientists of Peter the Great St. Petersburg Polytechnic University (SPbPU) and Delft University of Technology developed a technology for obtaining new metal structures by selective laser melting method (additive technology of manufacturing three-dimensional objects from metal powders). Key findings of the research have been described in an article “Functionally graded Inconel 718 processed by additive…
