Scientists add asphalt to lithium batteries that charge up to 20 times faster

You could say these researchers took a faster road.

New water-based lithium-ion battery will never explode in your face

Someone send Samsung the memo.

Promising Zn-Mn battery can store a lot of energy, far cheaper than Lithium-ion

Researchers from Pacific Northwest National Laboratory have found a way to reliably produce batteries that are very cheap, but can store a lot of energy.

What an overheated Lithium-ion battery looks like, inside and out

Lithium-ion batteries have pervaded most mobile technologies, including phones, notebooks or electric vehicles. Scientists involved in lithium-ion batteries are mainly interested in increasing the energy density so they can last longer and accelerating the charging time, but also avoiding failures. You can watch on YouTube a myriad of such fails, like batteries exploding and such. Thankfully, these events are particularly rare, yet they signal there’s still much room for improvement. University College London researchers were interested in studying how lithium-ion batteries perform under a certain kind of stress resulting from overheating, and recorded the first thermal failure using thermal imaging and non-invasive high speed imaging techniques to observe the internal structure. This way, they recorded both what happens outside and inside the battery when it overheats.

One single scrap car battery could be turned into solar cells that power 30 homes

Lead-acid car batteries used to be the norm, but luckily we’re seeing a massive shift towards more efficient and environmentally friendly alternatives like lithium-ion. Still, there are fleets of hundreds of millions of cars that still employ these archaic and toxic batteries. Typically, manufacturers try to have car owners bring their old lead-acid batteries, which are then converted into more
