Novel Gel Electrolyte for Efficient Rechargeable Battery UNIVERSITY OF WATERLOO


Rechargeable lithium-ion batteries have recently become infamous for causing explosions, and are known to have issues relating to efficiency. With lithium ion-based batteries so prevalent in today’s technology, the need for a safer, more efficient battery is clear. 
Rechargeable lithium-ion batteries have recently become infamous for causing explosions, and are known to have issues relating to efficiency. With lithium ion-based batteries so prevalent in today’s technology, the need for a safer, more efficient battery is clear. This Nanotechnology Engineering team has designed a novel aqueous gel electrolyte that includes silica nanoparticles and polyvinyl alcohol (PVA) to reduce corrosion and induce thixotropy, the property of a solution becoming liquid-like when shaken or stirred and solid-like when left alone. This new design will improve upon the safety and efficiency of the lithium-ion battery.

Cold Increases Service Life The Influence of the Operating Temperature on the Service Life and Reliability of Switching Power Supplies By Dipl.-Ing. (FH) Stefan Bergstein, Product Manager of EMTRON electronic GmbH-Bodo´s Power Systems




Cold Increases Service Life The Influence of the Operating Temperature on the Service Life and Reliability of Switching Power Supplies By Dipl.-Ing. (FH) Stefan Bergstein, Product Manager of EMTRON electronic GmbH-Bodo´s Power Systems

 The question of whether to use a transformer power supply or a switch-mode power supply is no longer dicussed today. In addition to superior technical properties, switched-mode power supplies impress with low costs, low weight and little space requirement. Certain requirements such as PFC (Power Factor Correction > 0.9 and sinusoidal mains current) can only be met with switched-mode power supplies. The question remains, what are the greatest influences on the service life and reliability of a switched-mode power supply?

Leading-Edge Power Modules for the New Era in Traction Converters By Vishal Jadhav, Wilhelm Rusche and Andre Lenze; Infineon Bodo´s Power Systems




Leading-Edge Power Modules for the New Era in Traction Converters Today, 55 percent of the world’s population live in urban areas, a proportion that is expected to increase to 68 percent by 2050 [1]. With this ever-increasing urban population, in combination with an increasing number of commuters on public transport, and a growing awareness of energy-efficiency and emission-free transportation systems, traction application is back in the limelight. A megatrend like urbanization provides a tailwind to improve, enhance and innovate today’s traction converters and components within its ecosystem. Power semiconductors, which are core components of traction converters enhancing their reliability, efficiency and longevity, are of utmost importance.
