Did you know that liquid can also be used as a battery?

Liquids can also be used as batteries, did you know? The government and public utilities need a large-scale energy storage device to solve the instability of wind and solar energy. One possibility is a mobile battery, which uses liquid to store and release energy. However, a problem with this device is its low energy density, which means that the size of the device determines how much energy it can store. Now, the Pacific Northwest National Laboratory in Washridgeland, England has developed a new mobile battery that can store twice the energy of existing mobile batteries. The solid electrode of a traditional battery is replaced by two parts of a liquid electrolyte. The liquid is placed in a separation tank, and when it flows into the battery tank, the chemical reaction between the liquid passes through the porous membrane, allowing it to discharge and charge. By adding liquid, the energy storage of the battery can be easily expanded. The cost per kilowatt hour of mobile batteries is also lower than that of lithium batteries, which are usually used in mobile devices. In this way, mobile batteries may be the best choice for the grid. However, the low energy density of mobile batteries also limits their ability to supply power to parts of the grid, which may be restricted in cities because they require a lot of space. The new mobile battery uses black galvanized sheet liquid and transparent galvanized sheet liquid. According to laboratory standards, a mobile battery can release 12 watt-hours of electricity, which is equivalent to the capacity of two Apple batteries. In contrast, mobile batteries release 167 watt-hours of energy per liter of electrolyte. In contrast, brominated batteries release 70 watt-hours of energy per liter of electrolyte, while vanadium batteries release 15 to 25 hours of energy per liter of electrolyte. energy. (For reference, an electric car needs 350 watt-hours for every 1.6 kilometers in a city.) Theoretically, the researchers say that if more chemicals are dissolved in the new battery, it can release up to 322 watt-hours of electricity. Traditional lithium batteries used in portable electronic products and some small electric vehicles can release 233 watt-hours of electricity. Researchers say their new zinc-plated batteries are safer. Unlike other mobile batteries, the liquid inside the battery is not acidic. Therefore, new mobile batteries should not be equipped with valuable materials to prevent corrosion. In addition, the new battery can be used in extreme weather conditions of minus 20 to 50 degrees Celsius, which makes it a wider operating window than other batteries. Other batteries require heating and cooling systems to help them adapt to the electrical equipment used. One problem with the laboratory battery prototype is that the strengthening of metallic zinc will weaken the battery's discharge capacity. Researchers have shown that this enhanced use can be attenuated by participating in alcohol, and they are still studying whether other additives can control this response. The scientists plan to experiment with larger batteries, which can release 100 watt-hours of electricity. They reported their findings in the online edition of Nature Communications on February 24.
