    An unexpected discovery has led to a rechargeable battery that's as inexpensive as conventional car batteries, but has a much higher energy density. The new battery could become a cost-effective, environmentally friendly alternative for storing renewable energy and supporting the power grid.
    A team based at the Department of Energy's Pacific Northwest National Laboratory identified this energy storage gem after realizing rechargeable zinc-manganese batteries work in a different way than they had assumed.
    In other words, they applied simple fix by adding manganese ions to the electrolyte in a new test battery and put the revised battery through another round of tests. The test battery was able to reach a storage capacity of 285 milliAmpere-hours per gram of manganese oxide over 5,000 cycles, while retaining 92 percent of its initial storage capacity.

    Elon Musk will love this. I wonder if he knows about it yet? Lighter, longer-lasting batteries for his battery-factory in Nevada for his battery-electric cars.
