lithium 3400mah 3.7v 18650 battery

　　The United States develops nanostructured lithium 3400mah 3.7v 18650 batterywith high performance and low cost

　　The nanostructure on the platinum-nickel-molybdenum surface is 81 times more efficient than the platinum-carbon composite catalyst currently on the market. Moreover, after being used for a period of time, this three-metal compound can still maintain a catalytic efficiency of 95%, which is significantly better than the catalytic efficiency of 66% or less of a platinum-nickel catalyst.

　　Researchers at UCLA's Henry Samueli School of Engineering and Applied Science lead a team of researchers who have developed nanostructures made using three metal compounds that increase fuel cell efficiency and efficiency while reducing production costs. Durability. Their solution solves a thorny problem that has stagnated the technology.

　　Yu Huang, an associate professor of materials science and engineering at UCLA and the principal investigator of this study, published the research results in the June 12 issue of Science.

　　As a clean energy technology, proton exchange membrane lithium 3400mah 3.7v 18650 batteryhave a wide range of applications, including use in zero-emission vehicles. lithium 3400mah 3.7v 18650 batterywork by triggering a chemical reaction between hydrogen fuel and oxygen in the air to produce electricity, and the byproduct they produce is water instead of the pollutants and greenhouse gases emitted by traditional cars.

　　The chemical reactions that occur in proton exchange membrane lithium 3400mah 3.7v 18650 batteryare catalyzed by metals. One of these chemical reactions is a redox reaction, which often uses platinum as a catalyst. But the high cost of platinum has been a major impediment to widespread adoption of fuel cells. Scientists have investigated alternative catalysts including using platinum-nickel compounds, but so far have not come up with a viable solution.

　　Researchers used a surface engineering technique called surface doping to create a fuel cell that is more efficient, longer-lasting and cheaper to produce. They added a third element called molybdenum to the surface of platinum-nickel nanostructures in the battery. three metals. This change makes the alloy surface more stable and prevents the loss of nickel and platinum over time.

　　The study found that the nanostructure on the platinum-nickel-molybdenum surface was 81 times more efficient than platinum-carbon composite catalysts currently on the market. Moreover, after being used for a period of time, this three-metal compound can still maintain a catalytic efficiency of 95%, which is significantly better than the catalytic efficiency of 66% or less of a platinum-nickel catalyst.

　　We found that the addition of a third transition metal significantly improved efficiency and durability and reduced cost, said Huang, who is also a member of the California Nanotechnology Institute. In addition, it shows that doping technology can also be applied to a range of catalysts, while opening up a new path for catalyst engineering to find efficient catalysts for environmental protection, energy production and chemical products.
