    Tesla employees say the company is manufacturing a high ratio of flawed parts and vehicles that need rework and repairs. The electrical vehicle maker has had to ship some flawed parts to remanufacturing facilities to avoid scrapping them, rather than fixing them in-line, according to sources; Tesla denies this. CEO Elon Musk is under pressure to ramp up production of the Model 3 sedan, Tesla's first mass-market electric vehicle. _____________________________________________________________________________________________________________________ Luxury automaker Tesla is manufacturing a surprisingly high ratio of flawed parts and vehicles, according to several current and former employees, leading to more rework and repairs than can be...

    Commentary: In a video posted online, a customer reportedly wants to check if a new battery is authentic -- using his teeth. Cue explosion.Some things might seem obvious. But even these things are worth mentioning occasionally. Please, therefore, allow me to say these words: Don't bite your phone battery. I base this apparently absurd entreaty on a video that's making its way around the web. It appears to show someone in a Chinese electronics store. As the Taiwan News reports, the customer was looking for a replacement battery for his phone last Friday. The news outlet insists that the action...

    Former Aston Martin designer to challenge Tesla with claims of dramatic breakthrough Henrik Fisker at CES in Las Vegas, says the solid-state batteries have the potential to be much cheaper to make than lithium-ion batteries. ____________________________________________________________________________________________________________________________________ In an announcement designed, surely, to take some of the wind from Tesla’s sails, Henrik Fisker is claiming to have made a dramatic breakthrough in battery technology. Fisker, who left a job as chief of design at Aston Martin to set up his own eponymous car company, says that he’s filed patents on a new design of so-called “solid state” batteries, which can theoretically...

    Brookhaven National Laboratory scientists have observed an unexpected phenomenon in lithium-ion batteries – the most common type of battery used to power cell phones and electric cars. As a model battery generated electric current, the scientists witnessed the concentration of lithium inside individual nanoparticles reverse at a certain point, instead of constantly increasing. This discovery, published in the journal Science Advances, is a major step toward improving the battery life of consumer electronics. Esther Takeuchi, a SUNY distinguished professor at Stony Brook University and a chief scientist in the Energy Sciences Directorate at Brookhaven Lab said, “If you have a...

    The company has big plans to make electric cars cool. t’s an exciting time for solid state batteries. BMW announced last month that it’s teamed up with Colorado-based battery developer Solid Power, which could see the automaker ditch the liquid electrolyte lithium-ion cells of yesteryear in favor of a solid alternative that’s safer, higher-energy, and simpler. “I don’t wanna sit here and claim that all the technical challenges are solved,” Doug Campbell, the CEO of Solid Power, tells Inverse. “It’s a vote of confidence in that some of the fundamental historical concerns for solid state, I think this is a...

Empa researchers have succeeded in doubling the electrochemical stability of water with a special saline solution. This takes us one step closer to using the technology commercially.

    Six years ago, Jiaxing Huang discovered crumpled graphene balls -- novel ultrafine particles that resemble crumpled paper balls. Credit: Jiaxing Huang ___________________________________________________________________________________________________________________________________________________________ Lithium metal-based batteries have the potential to turn the battery industry upside down. With the theoretically ultra-high capacity of lithium metal used by itself, this new type of battery could power everything from personal devices to cars. "In current batteries, lithium is usually atomically distributed in another material such as graphite or silicon in the anode," explains Northwestern University's Jiaxing Huang. "But using an additional material 'dilutes' the battery's performance. Lithium is already a metal, so why not...

    This illustration shows the formation of complex ion clusters during the cycling of a lithium-sulfur battery cell. The clusters consist of cationic polymer binders, battery electrolyte, and anionic sulfur-active materials. Credit: Berkeley Lab _______________________________________________________________________________________________________________________________________ Lithium-sulfur batteries are promising candidates for replacing common lithium-ion batteries in electric vehicles since they are cheaper, weigh less, and can store nearly double the energy for the same mass. However, lithium-sulfur batteries become unstable over time, and their electrodes deteriorate, limiting widespread adoption. Now, a team of researchers led by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have reported...

    Most phone owners come to realize that an old battery is a weak battery, one that gradually loses capacity. But it turns out that an old battery can also be a performance-killing battery, as evidenced by Apple's recent revelation: Owing to an intentional software feature, some iPhones will run slower if they have older, failing batteries. Fortunately, there's a simple fix: Get a new battery. Previously, Apple charged $79 for such a swap, but effectively immediately, you can get a replacement battery from Apple for just $29. That's for any iPhone 6 (£27.00 at uSwitch) or later.

    A team of engineers led by 94-year-old John Goodenough, professor in the Cockrell School of Engineering at The University of Texas at Austin and co-inventor of the lithium-ion battery, has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage. Goodenough’s latest breakthrough, completed with Cockrell School senior research fellow Maria Helena Braga, is a low-cost all-solid-state battery that is noncombustible and has a long cycle life (battery life) with a high volumetric energy density and fast rates of charge and discharge. The engineers describe...

    A disturbing Reddit thread claims that in 2008 the ex-business partner of James Alefantis, DC chef and restauranteur Carole Greenwood, caught Alefantis in the act of sexually battering her then 17 year-old son. Subsequent internet postings identified the location of the alleged crime scene as being Comet Ping Pong Pizza, a DC ping pong-themed pizzaria featuring live music acts. Citing a "family emergency", Greenwood abruptly terminated her business dealings with Alefantis and disappeared, finally surfacing as Executive Chef at Bethesda's Food & Wine Co. An anonymous poster to the thread, presumably Alefantis, objects to the dark story: "Why wouldn't I...

    Video at link. Yesterday we saw USC left tackle Chuma Edoga get himself ejected from a game against Utah State after getting a little bit too physical with a ref during the heat of the moment, but this video from the junior college ranks is even worse. Mt. San Antonio offensive lineman Bernard Schirmer took unsportsmanlike conduct to the next level when he allegedly punched a ref while being restrained, knocking the ref to the ground and later being taken away in handcuffs by local authorities. He was charged with suspicion of battery.
