The MIT team has developed a 'breathing' flow battery that will not only store power for long periods of time, but will cost as little as one-fifth the cost of the existing technology for $ 20 to $ 30 per kWh. For the intermittent renewable energy (solar, wind) power output to avoid the fear of not in time, this rechargeable battery has a great opportunity as a new power storage equipment.
Wind and solar have incredible power generation potential, but they have a common barrier that is intermittent, which means that some days they can power the entire city and some times even one village can not supply electricity In order to store these Energy, we use a variety of battery technologies, and although there are many breakthrough, innovative theories on paper, the real impact is so small that Tesla CEO Elon Musk mercilessly laughed at these 'Innovative.' For Musk, his batteries dominate the market, albeit at a much higher cost.
Recently, a research team at the Massachusetts Institute of Technology (MIT) developed a new battery that works very simply, but is an unexpected discovery that brings hope to the battery world, and for the first time, they decided to use very cheap and abundant sulfur and water blends The solution was the battery anode (negative), but it took some time before finding a cheap oxidized liquid salt solution for the cathode (positive) material, ultimately creating an ultra-low cost rechargeable battery.
The use of a liquid salt solution as cathode repeats the absorption and release of oxygen. When oxygen enters the cell, electrons are released from the anode to the external circuit. When oxygen flows out, the electrons return from the cathode to the anode. This charging and discharging characteristic also allows the researchers to laugh at this 'Will breathe' battery, but unlike the human breath spit out carbon dioxide emissions, this battery breathing breath are all oxygen.
Most notably, the cost of storing new batteries is $ 20- $ 30 / kWh, but storage costs for lithium-ion batteries like cell phones are as much as $ 100 / kWh Researchers MIT Materials Science Professor Yet-Ming Chiang said that if scientists were to pursue the high energy density of batteries at high cost, this would not be the right way in the long run. To save a lot of energy, we must consider abundant and readily available raw materials.
Finally, the total cost of a new battery (including the total cost of the cathode, anode, and electrolyte materials) is just one-thirtieth of the cost of lithium-ion batteries. Although the energy density is slightly lower than today's lithium-ion batteries, 500 times the power system, with absolute cost advantage.At present, the new battery prototype only coffee cup size, the future can be combined into a larger system for storing wind and solar power.Researchers also plan to extend the battery life To 1,500 hours or more.
