By modifying the structures of molecules used in the positive and negative electrolyte solutions, and making them water soluble, the Harvard team was able to engineer a battery that loses only one percent of its capacity per 1000 cycles.
Harvard scientists have developed a new flow battery which stores energy in liquid, works 10 years without energy loss and is much safer than lithium-ion batteries.
After a few years of heavy use, most lithium-ion batteries suddenly loose a lot of storage capacity. You surely recognize this from your smartphone, but that’s also a problem for energy storage which should last a very long time to store solar energy. Scientists at Harvard University have found a possible solution.
The new technology promises a battery definitely lasting ten years without losing much capacity. The solution is applied to a so-called flow-battery. The flow battery stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.
