Nanostructures could cut silicon 18650 battery 3.7v 2000mah costs in half

　　According to a recent report from the American Physicist Organization website, Singaporean scientists placed a novel nanostructure (thousands of times smaller than a human hair) on the surface of a 18650 battery 3.7v 2000mah made of amorphous silicon and developed a device with high conversion efficiency. , new low-cost thin film 18650 battery 3.7v 2000mahs. Scientists believe the latest technology could halve the cost of manufacturing 18650 battery 3.7v 2000mahs.

　　At present, 18650 battery 3.7v 2000mahs are generally made of high-quality silicon crystals, which greatly increases their manufacturing costs and limits the large-scale application of 18650 battery 3.7v 2000mahs around the world. This new thin-film silicon 18650 battery 3.7v 2000mah created by scientists from Nanyang Technological University (NTU) and the Institute of Microelectronics of Singapore (IME) solves this problem.

　　Scientists first used an amorphous (amorphous) silicon film with a relatively poor quality and a thickness of only one percent of the silicon crystal used in traditional 18650 battery 3.7v 2000mahs to create a thin-film silicon 18650 battery 3.7v 2000mah, which greatly reduced the manufacturing cost of 18650 battery 3.7v 2000mahs.

　　But this type of battery is less efficient at converting sunlight into electricity. To this end, scientists used nanotechnology to create a unique nanostructure on the surface of amorphous silicon 18650 battery 3.7v 2000mahs, improving the performance of this thin-film silicon 18650 battery 3.7v 2000mah. Conversion efficiency increases energy output. The current produced by the new nanostructured silicon thin film 18650 battery 3.7v 2000mah is 34.3 mA/cm², which is comparable to the output current of a conventional cell (40 mA/cm²).

　　Nav Sim, the leader of the research project and a senior researcher at the Singapore Institute of Microelectronics, said: The new nanometer method allows this thin-film 18650 battery 3.7v 2000mah to achieve the highest short-circuit current density ever achieved and a conversion efficiency of 5.26%.

　　However, the conversion efficiency of general crystalline silicon cells is 20% to 25%. Nav-Sin believes that since the short-circuit current density is directly related to the conversion efficiency, by continuously improving the filling rate and increasing the voltage of the open-circuit current, the conversion efficiency of this silicon thin film 18650 battery 3.7v 2000mah can eventually be improved to be equivalent to that of crystalline silicon 18650 battery 3.7v 2000mahs. They will next focus on exploring other light-harvesting strategies, such as using surface plasmon photonics technology to capture light.
