battery explosion

Here’s what a smartphone battery looks like inside just before it explodes

December 7th, 2016

We’ve all heard plenty about exploding batteries this year, so it’s kind of funny that scientists are just now digging into what actually causes rechargeable power sources to go nuclear. A new paper published in the Journal of The Electromechanical Society details how researchers used an X-ray to track the changes happening inside a battery as …

How to stop your smartphone battery from exploding

September 29th, 2016

2016 may be remembered as the year self-driving cars started to become a thing, or as a low point for American democracy. But it will also be remembered as the time that expensive electronics started doubling as handwarmers. Apple and Samsung devices (and washing machines!) have started going boom with slightly worrying regularity, all because of …

Battery Technology Advancements

Revolutionary new battery runs on gravity

July 8th, 2016

It’s the same old story: batteries are holding us back. Technology is advancing so quickly across so many industries, but the next-generation batteries needed to power all of these advancements more efficiently are nowhere to be found. Researchers are hard at work on improving existing battery tech though, and they’re also developing exciting new kinds of batteries …

Lithium-Oxygen Battery Research

Breakthrough battery prototype can store five times the energy of current Li-ion batteries

January 25th, 2016

It’s the question that smartphone users have been asking for years: When will we get vastly better battery power in our devices? Thanks to some breakthrough research, significantly better battery technology may arrive sooner than expected. IFLScience points us to new research published in the Nature science journal that describes a prototype for a so-called “lithium-oxygen” battery that is …

Lithium Ion Battery Stanford Researchers

Breakthrough research could solve a major problem with lithium-ion batteries

January 12th, 2016

Lithium-ion batteries are fantastic but they’re also unstable and can be explosive when they overheat. Researchers at Stanford University have been working on how to fix this problem and have developed a new kind of lithium-ion battery that automatically shuts down once it reaches a certain temperature and won’t switch back on until it has …

Smartphone Battery Life

New breakthrough could lead to huge battery improvements

July 9th, 2014

A research team at the University of Alberta may have made a breakthrough that ultimately leads to dramatic improvements in the batteries that power everything from laptops and smartphones to medical devices and tools. According to lead researcher Xinwei Cui, the lithium-ion battery technology his team is currently developing charges faster, lasts longer and outputs more power …

A cotton T-shirt may one day charge your cell phone

July 4th, 2012

Two engineers at the University of South Carolina conducted research that showed a modified store-bought T-shirt can act like a supercapacitor and store an electrical charge. “We wear fabric every day,” said Xiaodong Li, a professor of mechanical engineering at the school. “One day our cotton T-shirts could have more functions; for example, a flexible …

Apple to improve battery life by increasing cell density

February 17th, 2011

An Apple patent uncovered on Thursday describes new technology Apple is experimenting with in an effort to increase the battery life in its device lines. The patent filing, entitled Increasing Energy Density in Rechargeable Lithium Battery Cells, describes a unique multi-pronged approach to the problem of poor battery life in consumer electronics. Apple is investigating the use of a …

Garmin recalling 1.25 million nüvi navigation devices

August 25th, 2010

Just a quick PSA: Garmin has just announced that they are voluntarily recalling 1.25 million nüvi navigation units due to the possibility of faulty batteries. A press release explains that some devices, with a specific printed circuit board design, could contain defective third-party batteries that, “in rare circumstances, increase the possibility of overheating, which may lead to a …
