    Duracell, the battery unit of Warren Buffett’s Berkshire Hathaway Inc., sued the maker of Energizer batteries on Tuesday, accusing it falsely advertising that its Energizer MAX batteries last up to 50% longer than other alkaline batteries. The lawsuit follows Energizer Holdings Inc.’s own lawsuit last Sept. 30 accusing Duracell of falsely advertising that its then-new “Optimum” batteries were more powerful and lasted longer than rival batteries. Duracell filed counterclaims alleging false advertising in that case. It is now accusing Energizer of having “doubled down” by claiming on battery packages, on printed coupons and through in-store advertising that MAX batteries are...

    While smartphones, smart homes and even smart wearables are growing ever more advanced, they're still limited by power. The battery hasn't advanced in decades. But we're on the verge of a power revolution. Big technology and car companies are all too aware of the limitations of lithium-ion batteries. While chips and operating systems are becoming more efficient to save power we're still only looking at a day or two of use on a smartphone before having to recharge. While it may be some time before we get a week's life out of our phones, development is progressing well. We've collected...

    Fluctuating solar and wind power require lots of energy storage, and lithium-ion batteries seem like the obvious choice—but they are far too expensive to play a major role. A pair of 500-foot smokestacks rise from a natural-gas power plant on the harbor of Moss Landing, California, casting an industrial pall over the pretty seaside town. If state regulators sign off, however, it could be the site of the world’s largest lithium-ion battery project by late 2020, helping to balance fluctuating wind and solar energy on the California grid. The 300-megawatt facility is one of four giant lithium-ion storage projects that...

    The self-parking ID.3 shows how big-volume car makers are unleashing a new generation of technologically advanced vehicles that will allow them to wrestle back leadership of their industry from upstarts like Tesla Inc. But in order for the industry’s huge bet on electrification to pay off, car makers will have to sell millions of the vehicles to mass-market consumers, not just an elite group of wealthy, environmentally conscious consumers. Ultimately, it expects to build one million electric cars with this technology by 2025 and a total of 15 million before upgrading the vehicle’s core technology. Bumper to bumper, the ID.3...

    Transitioning to renewable energy across society will require many changes, including more batteries. Energy storage is crucial for making sure that inconsistent renewable sources, like wind or solar, can stay humming even when the weather isn't going their way. But batteries have their own problem in the form of the commonly used lithium. Researchers at the Indian Institute of Technology (IIT) Madras have come up with what could be a possible replacement: a rechargeable iron ion battery that uses mild steel as the anode. “The major limitations of lithium-ion batteries are the unavailability of lithium in conjunction with the safety...

    (Reuters) - The “great majority” of solar cells being produced at Tesla Inc’s factory in upstate New York are being sold overseas instead of being used in the company’s trademark “Solar Roof” as originally intended, according to documents reviewed by Reuters. The exporting underscores the depth of Tesla’s troubles in the U.S. solar business, which the electric car maker entered in 2016 with its controversial $2.6 billion purchase of SolarCity. Tesla has only sporadically purchased solar cells produced by its partner in the factory, Panasonic Corp, according to a Buffalo solar factory employee speaking on condition of anonymity. The rest...

    The Trump administration has targeted an Obama-era regulation credited with helping dramatically reduce toxic mercury pollution from coal-fired power plants, saying the benefits to human health and the environment may not be worth the cost of the regulation. The 2011 Obama administration rule, called the Mercury and Air Toxics Standards, led to what electric utilities say was an $18 billion clean-up of mercury and other toxins from the smokestacks of coal-fired power plants. Overall, environmental groups say, federal and state efforts have cut mercury emissions from coal-fired power plants by 85 percent in roughly the last decade. Mercury causes brain...
