Scientists of Harvard University have significantly improved the previous version of their battery battery, which can store energy from renewable
Sources during the day. It differs in that it is made of available and cheap materials and safer.
Lithium-ion batteries are great for smartphones and electric vehicles. But for storing energy obtained from wind generators and solar panels, they are not suitable due to fluctuations in the network due to the reasons associated with the change of day and night and a change in the wind force until complete calm. With the advent of liquid batteries, this problem was solved.
Streaming batteries store energy in a “liquid” form. Damaged electrolytes are in external containers. To get an electric charge, it is necessary to pump liquids through a special membrane. The power of the battery can be adjusted by changing the capacity of the tanks or the area of the membrane. If necessary, the stream can be stopped without fear of the loss of charge and sudden temperature differences.
Professor Michael Aziz and his colleagues, taking into account previous experience, developed an environmentally friendly battery based on safe non -toxic and heat -resistant carbon compounds, iron and potassium. The service life of the battery is at least 1900 cycles, which is much more than that of lithium-ion batteries.
Currently, scientists are working on increasing energy density, since 19 W is clearly not enough for the battery. In their opinion, it will take about 3 years to solve this problem.
