MIT research team has developed a new type of liquid metal battery

the energy storage capacity of renewable energy has always been a major obstacle to the development of renewable energy. A team of researchers from the Massachusetts Institute of Technology (MIT) has developed a new type of all liquid metal battery system, which is cheap and has a long service life. According to the research team, this device can make renewable energy such as wind and solar energy have the ability to compete with traditional energy

donaldsadoway, the project leader and MIT professor of material chemistry, has been committed to exploring and researching applications that can reach the electrical scale. Its definition is: the stress value "liquid battery" required to make the metal produce a constant creep deformation or creep rate within a specified time. We have reported that the MIT scientific research team also led by donaldsadoway has developed the prototype of liquid metal battery, Now his team has launched an improved version of the new liquid metal battery

there is no solid inside the liquid metal battery, but people often neglect their quality problems. The cathode, anode and energy storage components of the battery are all made of molten liquid. The research team has tested many different combinations over the years. In the earliest design, liquid antimony and liquid magnesium were used as electrodes, and sodium sulfide was used as energy storage elements. Due to different densities, several liquid metal materials will not mix with each other, but will have a layered structure like oil and water

when liquid antimony was originally used as the electrode material, the system needed to maintain a high temperature of 700 C before it could operate. After improvement, researchers used the mixed metal of lithium, lead and antimony to make the electrode, which reduced the working temperature to 400~500 C. At the same time, researchers found that using this new material electrode obtained more benefits, higher voltage than using antimony only, and lower melting point than using lead only

the research team said that the new version of the battery can work at a lower temperature, with a longer service life and a lower theme cost, which increased the financial expenses of the chemical and non-ferrous industries by 21%, 21% and 20% year-on-year respectively in 2014. It was found in the test that after ten years of daily charge and discharge, the battery can still maintain 85% of the initial conversion efficiency (the initial conversion efficiency is about 70%)
