Soft polymer-based electrolytes are emerging as safer, more flexible alternatives to liquid electrolytes in rechargeable batteries, particularly lithium-ion and lithium-metal systems. They come in ...

Lithium-ion batteries face safety concerns as a result of internal separator issues which often lead to short circuits. Scientists have now developed a method to improve the stability and properties ...

Rechargeable lithium-ion batteries don’t last forever. Over time, they hold onto less charge, eventually transforming from power sources to bricks. One reason: hidden, leaky hydrogen, new research ...

The ongoing electrification of everyday items has resulted in the proliferation of batteries, and spurred continued development for automotive and grid use. Lithium-ion batteries still dominate the ...

Lithium-ion batteries are miraculous. They’re strong enough to run a vehicle, and they can be recharged at any outlet. Their commercial debut, in 1991, and popularization over the next two decades, ...

Wesley Chang is an assistant professor of mechanical engineering and mechanics at Drexel University. Rechargeable batteries are great for storing energy and powering electronics from smartphones to ...

More and more devices now come kitted out with rechargeable lithium-ion batteries — you know, the ones that look like the old-style AA or C cell batteries, but are a slightly different size. The most ...
