Cheap Battery Made from Abundant Materials

The three primary constituents of the battery are aluminum (left), sulfur (center), and rock salt crystals (right). All are domestically available Earth-abundant materials not requiring a global supply chain.

  Lithium is expensive, hard to extract in the quantities that will be required to meet demand for EV batteries and renewable energy storage, and often dangerous. Formulating a battery that doesn’t need lithium, even for some applications, would help ensure the lithium supply we have now lasts longer

Easy Integration of Supercapacitor Power Back-up

Frederik Dostal, Subject Matter Expert, Power Management, Analog Devices

   One of the major trends over the last two decades is to replace mechanical systems with electronic systems wherever possible. Deploying an electronic system usually has the advantage of offering faster and more accurate responses, while being more reliable due to having no physical wear and te

Piezoelectric Effect Could Power Miniature Nanoscale Sensors

A charge redistribution model shows how charge flows across the phase interfaces in a 2D piezoelectric material of molybdenum (blue) and tellurium (yellow). The red areas are electro-deficient, the green is electron rich.

­ The piezoelectric effect is quite an unusual phenomenon that could become very important to the electronics industry in the next few years. The effect is achieved in applicable materials by applying mechanical stress to provide an electrical charge. The electric field is created because the mechanical stress

Nanocrystals Enable Smaller Off-the-Shelf Three-Phase Filter

Kemet's new range of three-phase filters suppress the noise in electronic equipment with superior attention characteristics

­   Three-phase filters are a necessary component in many applications, particularly in the industrial and medical areas, to ensure circuits operate without interference, reducing errors. Currently, they tend to be bulky, grey boxes which may need quite a bit of engineering work to perform their tas

 ACE Batteries Drive LFP Technology Closer to Li-ion for EVs

How the prismatic cells fit directly into the battery pack

When modern EVs were introduced, the main reason for their initial slow sales was the range. However, battery technology has progressed and now some of the latest vehicles can get almost 600 miles on a full charge. As always in engineering, when one problem is solved another crops up, or in the case of electric veh
