Tesla has patented a new “tabless” battery cell design that it says improves on existing designs. It's way more important than it sounds, says Elon Musk. "There’s nothing wrong with tab technology, but streamlining battery designs to remove them could save a lot of time, materials, and money...

While the big Android smartphone players like Samsung, Huawei, LG and others tend to dominate the headlines and the markets, occasionally, smaller companies or corporations from other markets will come out with crazy designs. Caterpillar, for example, has a lineup of rugged, steel bodied steel...

Apple's missed revenue targets have sent investors scrambling for explanations, and a few pointed fingers at Apple's 2017/2018 CPU throttling scandal. Apple started a relatively affordable program to replace batteries in older iPhones for $29, and some analysts thought the program could put a...

Advancements in lithium Ion battery tech are largely responsible for explosive growth in other areas of technology, such as smartphones, electric cars, and autonomous robots. But those applications are often hampered by a unfortunate propery of lithium ion batteries: they tend to explode. IEEE...

Aluminum air batteries are an enticing alternative to lithium ion ones, offering one of the "highest chemical energy-density storage materials we know of," according to researchers at MIT. But those metal air batteries have a major problem: they can lose 80 percent of their charge in a month...

Traditional lithium ion batteries are produced in fixed shapes, which limits their applications and often forces designers to build devices around a battery. However, a 3D printed battery could not only fit in any form factor, but be used as a more prominent structural element in devices...

Colorado startup Solid Power claims to have made a breakthrough in solid state lithium ion battery technology. Unlike a conventional lithium ion battery, which uses a "volatile, flammable, and corrosive liquid electrolyte," solid state batteries use a solid electrolyte. Solid Power claims their...

Former Tesla employee, Martin Tripp, is being sued by the company for stealing company secrets and he is striking back by tweeting pictures of flawed batteries. He claims these batteries have been installed in Model 3's and provided the VIN numbers of vehicles that supposedly have these...

How am I posting this message? Why is my laptop working? Is there a necessary fix? I already tried rebooting, and IT CAME BACK UP.

Channel NewsAsia is reporting that a flight from Guangzhou to Shanghai was delayed 3 hours yesterday after a power bank caught fire in an overhead compartment. China South Airlines stated that passengers were boarding flight CZ3539 when smoke and fire was seen coming from a passenger's bag in...

According to Bloomberg (WARNING auto play video), Apple is in talks with mining companies to buy cobalt directly from them rather than letting their battery suppliers who would normally do this. Apparently, Apple is wanting to ensure they have a good supply of cobalt for the next five years or...

HP has issued a recall for laptop batteries because they may overheat or cause a fire. These batteries are within 15 different model laptops. Some of these laptops have internal batteries that aren't user removable and they will provide a free service to have this replaced by a service tech at...

A few days ago we reported that Apple apologized for the iPhone slow down issue and would replace batteries for $29 this year. A lot of people were wondering if the batteries had to show up bad on a diagnostic, but a French tech blog, iGeneration, is reporting that an internal Apple memo states...

Elon Musk makes many statements, and promises, about his ventures all the time. Over at Bloomberg, they are opining that his promises for batteries in his new roadster and semi products are slightly unbelievable. I tend to side with their opinion. However, only time will tell and I suspect...

Thanks to researchers at Stanford we are getting closer to finally figuring out why Li-ion batteries are blowing up. They published this paper on Thursday. Basically growths called dendrites pierce through the separator, a membrane placed in between the cathode and anode causing a short...

Mothers in Michigan and Alabama have shared similar stories of their bluetooth-enabled fidget spinners that double as speakers catching fire while charging. The Consumer Product Safety Commission says that they are investigating the incidents. "Bluetooth-enabled fidget spinner" made me cringe...
