    Default Scientists now know why rechargeable batteries go bad, and may know how to fix them

    Sweet, sweet science is on its way to finding a cure for how lithium-ion batteries (like the one in your phone) lose their ability to hold a charge over time. Researchers at Lawrence Berkeley, Brookhaven, and Stanford have found a pattern to the erosion that happens at both anode and cathode ends of the battery, when previously it was assumed the erosion was uniform. The salt that forms at the anode side and the metallic erosion on the cathode side both latch onto microscopic imperfections, kind of like how a water droplets latch onto a piece of dirt to begin forming rain or a snowflake.
