Experts from the Massachusetts Institute of Technology (MIT) have stated that they were able to overcome two major problems of storing energy, increasing efficiency and lowering costs . We are talking about a decision suitable for the so-called flow batteries, the design of which implies the presence of two tanks with chemical agents. The tanks are separated by a membrane that does not allow liquids to mix, but allows them to exchange ions. The membrane is the most expensive element of the battery and in this case - the least reliable, since during operation, it inevitably corrode.
U.S. scientists proposed development allows a completely excluded from the membrane structure, the effect of applying the so-called laminar flow, which does not allow liquids to mix with each other. As reagents were applied liquid bromine and hydrobromic acid - the choice is not accidental, since these substances are cheap and widely available. Created a prototype battery has a density of 0.75 watts per cubic centimeter, which is three times more than in similar systems, and an order of magnitude higher than today's lithium-ion batteries.
