They create in the EU battery that stores renewable energy on a large scale

A new circulation battery that doubles the maximum voltage of conventional tanks, will help store large amounts of renewable energy through sources wind and solar, according to scientists at Stanford University.

Up to now, the types of liquids that can produce electric current are limited by the amount of energy that they can provide because they required very high temperatures or used products very toxic or expensive chemicals. The researchers therefore decided to try sodium and potassium which, when they are mixed together, form a liquid metal at room temperature.

Student Antonio Baclig pointed out that this metal has at least 10 times the available energy per gram than others for the fluid on the negative side of the battery. Therefore, specialists have found a suitable ceramic membrane made of potassium and aluminum oxide to keep the negative and positive materials separate by allowing the current to flow.

With this they doubled the maximum voltage of conventional flux batteries and the prototype remained stable for thousands of hours, which means that it can store more energy for its size, which reduces its cost of production.

They pointed out that the membrane prevents sodium from migrating to the positive, which is essential, being more effective at temperatures above 200 degrees Celsius. They experimented with a thinner, increasing the power output of the device and demonstrating that refining its design is a promising avenue.
