A battery's positive end (cathode) and negative end (anode) are two vital components that largely define how well it can ...

Researchers at the University of Oxford have developed a powerful new method to visualize an essential lithium-ion battery electrode component that had been extremely difficult to trace before. The ...

Up to now, it has only been possible to deduce indirectly why high-temperature batteries lose efficiency and durability while ...

You might have heard the common claim that electric cars aren’t really green – that their lithium-ion batteries rely on “blood” minerals such as cobalt, mined in terrible conditions. The critique had ...

An important figure of merit for all precision constant current sources is their active impedance. Which is to say, just how “constant” is their output held against changes in applied voltage?

Batteries have become deeply embedded in modern life. From laptops, mobile phones, wearable devices such as smartwatches and wireless earphones, to power tools, electric vehicles (EVs), and ...

We love coming across low mileage, unreasonably well-kept examples of otherwise forgettable cars, but this burgundy-on-burgundy 1988 Buick Riviera T-Type with just 22,000 miles on its digital odometer ...

This photo shows two men examining shredded material from Li-ion battery recycling. In a battery-recycling pilot plant near Vancouver, British Columbia, American Manganese engineers examine shredded ...

FROM the results of investigations on nylon capillary columns 1, it became apparent that there were two possible applications for the capillary system. The columns could be used to produce very high ...
