lithium 3400mah 3.7v 18650 battery

　　A US research team invented a manganese-hydrogen lithium 3400mah 3.7v 18650 batterythat can be recharged more than 10,000 times

　　With the continuous expansion of the scale of renewable energy development and utilization and the rapid rise of the smart grid industry, the importance of energy storage technology has become increasingly prominent. The reporter learned on the 7th that a research team led by Professor Cui Yi of Stanford University in the United States introduced a manganese-hydrogen lithium 3400mah 3.7v 18650 batterythat can be recharged more than 10,000 times and can achieve stable performance for more than 10 years. The results were published in Nature Energy.

　　According to the first author of the result, Dr. Chen Wei from the School of Materials Science and Engineering at Stanford University, the manganese hydrogen lithium 3400mah 3.7v 18650 batterythey invented uses high surface area carbon as the positive electrode current collector and water-soluble manganese sulfate salt as the electrolyte. Hydrogen controlled by a catalyst serves as the negative electrode. This lithium 3400mah 3.7v 18650 batteryis different from any previous water-based lithium 3400mah 3.7v 18650 batteryin terms of design, charging and discharging principles, testing methods and performance.

　　The results show that the manganese-hydrogen lithium 3400mah 3.7v 18650 batteryhas very excellent electrochemical properties, such as a stable discharge voltage of 1.3 volts, a high-rate discharge current of 100mA/cm2, a stable cycle of more than 10,000 times, and a high mass energy density of 139Wh/kg and Volumetric energy density 210Wh/L. Moreover, the lithium 3400mah 3.7v 18650 batterycan be easily scaled up for large-scale energy storage.

　　Large-scale energy storage is the core technology for realizing the popularization and application of renewable energy. Existing large-scale energy storage technologies (such as pumped water energy storage, compressed air energy storage) and various energy storage batteries (such as lithium-ion batteries, sodium-sulfur batteries, flow batteries) all have different problems and are far from meeting the needs of large-scale applications. Large-scale energy storage requires cheap, safe, high energy density and high stability. Cui Yi said: The invention of manganese hydrogen batteries will have an important impact on the pattern of large-scale energy storage and further alleviate the serious carbon emissions and air pollution caused by traditional fossil energy.
