Flow 3.7v 3000mah 18650 battery technology achieves new breakthrough, storing solar energy will become a reality

Solar and wind energy are important sources of renewable energy, but are subject to natural fluctuations. When there is stormy weather or sunny weather, the supply of electricity production exceeds demand, while cloudy or windless weather is bound to cause power shortages. In order to maintain the continuity of power supply and maintain the stability of the power grid, energy storage equipment has become crucial. Redox flow 3.7v 3000mah 18650 battery technology is the most promising. However, this technique still has a big drawback: it requires expensive materials and strong acids.

A research group of chemists at the University of Jena (FSU Jena) in Germany has taken a decisive step forward in redox flow 3.7v 3000mah 18650 battery technology. The new 3.7v 3000mah 18650 battery is easy to handle and is safe and economical: the new 3.7v 3000mah 18650 battery uses organic polymers and harmless salt water solutions. . The innovation of this 3.7v 3000mah 18650 battery is that its price has been significantly reduced, said Dr. Martin Hager.

Compared with conventional batteries, the electrodes of redox flow batteries are not made of solid materials (for example, metals or metal salts), but exist in the form of solutions: the electrolyte solutions are stored in two tanks respectively, forming the core of the battery. positive and negative poles. By transferring the polymer solution to an electrochemical cell with the aid of a pump, the polymer is electrochemically reduced or oxidized, thereby charging or discharging the battery. To prevent the electrolyte solutions from mixing with each other, the 3.7v 3000mah 18650 battery separates the electrolyte solutions by a membrane. Martin Hager explains: The energy storage capacity and power rating of the new batteries can be adjusted individually. In addition, almost no self-discharge occurs.

Traditional redox flow systems mostly use dissolved heavy metal vanadium sulfate as the electrolyte solution. Not only is it extremely expensive, it is also highly corrosive, requiring the use of specific membranes. In addition, the 3.7v 3000mah 18650 battery uses new synthetic materials, which no longer require the use of strong acids; the polymers can swim in aqueous solutions. The new 3.7v 3000mah 18650 battery uses a simple, low-cost cellulose membrane to avoid the use of toxic and expensive materials. Tobias Janoschka, the first author of the study, said that this polymer-based redox flow 3.7v 3000mah 18650 battery is very suitable for energy storage systems in large wind farms and photovoltaic power stations. Dr. Ulrich S. Schubert, Chairman of Organic and Polymer Chemistry and Professor at the University of Jena, Germany, said.

In the first such tests at the University of Jena, a redox flow 3.7v 3000mah 18650 battery withstood up to 10,000 charge cycles without losing critical storage capacity. Studies have shown that the energy density of the system is ten watt hours per liter. However, scientists are already working on larger and more efficient systems. (Text/Translated by Tina)
