Researchers continue to look for battery improvements, including increased capacity and voltage as tech innovation is driven by increased demand for better, smaller, safer batteries. From next-gen smartphones to longer-range electric cars…

The decline of standard battery performance at low temperatures and the environmental impact of mining the metals to create them is driving the search for sustainable energy storage. Recently, researchers at Uppsala University have…

With lithium-ion batteries powering almost all remote devices, their manufacturers have had to develop safety measures to limit peak voltage. These include devices that monitor charge-state and current flow, record the latest, full-charge…

While very few lithium metal batteries have actually overheated to the point of catching fire, given the number of devices in which they’re used these days, their safety features could be improved. Now, nanoengineers at the University of…

Picture a Lithium-ion battery that is safe, has high power and can last for a million miles. It's real, developed by a team in Penn State’s Battery and Energy Storage Technology (BEST) Center, and could be the answer to powering future…

The search for a commercially viable self charging battery continues. In 2017, McGill University researchers announced they were working on a self-charging battery that could harvest and store energy using light. Now, researchers at the…

There are so many possible variables in battery performance that testing of new technologies at every stage of the battery development process can take months or even years. And battery performance can make or break the electric vehicle…

Smartphone components generate sound waves at extremely high frequencies ranging from 100 million to 10 billion hertz. In phones, these devices are used mainly to filter the wireless cellular signal and identify and filter voice calls and…

Research led by UCL has revealed new insights into the workings of a lithium battery by virtually "unrolling" its coil of electrode layers using an algorithm designed for papyrus scrolls. In a recent study, researchers combined X-ray and…

While nothing is perfect, even a one-in-200,000 breakdown of lithium-ion batteries can trigger huge recalls like the 2006 incident of six million Sony lithium-ion packs. Now, scientists are closer to understanding exactly what happens…
