    Ten gigabattery scale battery factory projects in China, Europe and USA brian wang | August 8, 2017 |    A report published by Bloomberg Intelligence in June said factories planned by Chinese companies could have the battery capacity to produce more than 120 GWh by 2021 – enough to supply 1.5 million Tesla Model S vehicles. This will be over three times initial the battery cell capacity of the Tesla Gigafactory at 35 GWh.As of 2014, the projected capacity of Gigafactory for 2020 was to have been 35 gigawatt-hours per year of cells as well as 50 gigawatt-hours per year (5.7 MW) of battery...

    Miniature lithium-ion device could power medical devices or miniature robots. A new lithium-ion battery is one of the smallest ever made and the first battery to be created with a three-dimensional printer. Measuring less than a millimetre on each side, it fits comfortably on the head of pin and could potentially power tiny medical devices or miniature robots. 3D printers make objects from the ground up by depositing successive layers of material on top of each other. Most 3D printers manipulate plastic, which is useful for prototyping or crafting toys and knickknacks. Making a working battery required a custom machine...

    A graphene inspired electrode material that could help batteries hold more power has been developed by Chinese scientists. The large surface area of these cobalt oxide nanosheets is key to their electrochemical performance.Batteries are a cornerstone of modern life with most smartphones and laptops using rechargeable lithium ion batteries. As technology advances, the search is on for batteries that can pack more energy into the same space. Graphitic electrodes are commonly used in lithium ion batteries but suffer from low theoretical capacity. A viable alternative is to use metal oxides which have significantly higher theoretical capacities but in practice are...

    The crisis that has enveloped Boeing over the grounded Dreamliner, at a cost of billions of dollars in losses in addition to what has already been invested in it -- voluntarily by its owner/investors and coercively from taxpayers exemplifies perhaps more than any other redistributionist corporatism scheme why government intervention is more headache than help. Pass the industrial-strength Excedrin. Of immediate concern to the Chicago-based jet-manufacturer is the lithium-ion battery that powers so many of the 787s critical functions. Two instances of thermal runaway on Dreamliners owned by Japan-based airlines caused that country, and the U.S. Federal Aviation Administration,to...

    Just as the Department of Energy gave A123 Systems a vote of confidence by extending a deadline until 2014 to spend down its $249 million stimulus grant, the deeply troubled electric vehicle supplier experienced another setback. One of their batteries caused an explosion. The blast occurred yesterday morning in Warren, Mich. at General Motors Alternative Energy Center a research facility while performing on an A123 battery intensive tests designed to make it fail, the Detroit News reported. GM confirmed to Crains Detroit Business that chemical gases released by the battery caused the explosion. One employee was sent...
  • Transparent lithium ion batteries make electricity generating windows possible

    Energy-harvesting windows are a step closer with the development of a transparent lithium ion battery, created by US researchers at Stanford University. The electrodes are confined to a grid 35m wide, making them too narrow to be perceived by the naked eye.The electrodes pose the biggest challenge to transparent lithium ion batteries, as both anode and cathode materials are typically opaque. Yi Cui's team solved this problem by making them very thin. They set the electrode materials into a grid of trenches in clear polydimethylsiloxane (PDMS). By stacking and aligning the grids with additional layers of electrodes, it is possible...

    Enlarge ImageHybrid power. Carbon nanofibers (left) are coated with silicon (right) using a process known as chemical vapor deposition, making for light electrodes that store more energy. Credit: Li-Feng Cul et al., Nano Letters (2009) With $27 billion a year in sales, lithium-ion batteries already dominate the market for rechargeables. But there's always pressure to do better. Now researchers report that they've come up with a way to use nanotechnology to either significantly increase the energy storage capacity of lithium-ion batteries or reduce their weight while maintaining their current energy content. The new work could lead to everything from...
