Haze and other major pollutants such as sulfur-containing waste gas will seriously endanger human health. The reporter recently learned from Tianjin University that Professor Yang Quanhong, a researcher of the National Outstanding Youth Science Foundation of the university, made hydrogen sulfide and sulfur dioxide gas “green†quickly for the first time. Nano-sulfur particles with good dispersibility in water serve as electrode materials and functional separators, making lithium-sulfur batteries with excellent application prospects in electric vehicles perform well. This idea of ​​turning waste into treasure realized the combination of air pollution control and the development of new energy devices. The research results paper was published in the latest issue of the international energy field "Nano Energy".
A lithium-sulfur battery with an ultra-high energy density is one of the important directions for the development of electric vehicles in the future, and sulfur, as its positive active material, is responsible for the storage of energy. In order to break through the limitations of traditional treatment methods, the efficient conversion of sulfur from exhaust gas into active materials that can be used in lithium-sulfur batteries is an innovation that combines the treatment of pollutants and the development of new energy technologies.
Yang Quanhong said in an interview with a reporter from the Science and Technology Daily that since 2013, the research team has tried to transform air pollutants into key players in new energy devices. At present, experiments have proved that hydrogen sulfide and sulfur dioxide gas can play a role in lithium-sulfur batteries.†The effect of energy bars. Inspired by basic chemical reactions, the researchers used water as the reaction medium to achieve redox and sulfur dioxide gas oxidation, and the product was only sulfur nanoparticles and water. The resulting nanosulfur has good water dispersibility.
Prof. Lu Jun, a well-known battery expert at Argonne National Laboratory in the United States, told reporters that this groundbreaking work concept is very clever, killing two birds with one stone, and the resulting nano-sulfur particles have played a positive role in promoting the performance and industrialization of lithium-sulfur batteries.

1.2 The LED contains chips of two or three colors.
1.3 Colored or colorless, light-emitting diodes of the above colors can also be divided into four types: colored transparent, colorless transparent, colored scattering and colorless scattering. Scattered light emitting diode and LED can be used as indicator light.
Colloid appearance: colorless transparency, colored transparency, colored scattering, colorless scattering, etc;
Straight LED Lamp Beads are divided according to the specifications:
2.1 Shape: round lamp, square lamp, rectangular, surface light emitting tube, side tube, surface mounting microtube, etc.
2.2 Round lamps are divided into φ 2mm. φ 4.4mm. φ 5mm. φ 8mm. φ 10mm and φ 20mm, etc.
2.3 Generally φ 3mm LED is recorded as T-1; hold φ 5mm is recorded as T-1 (3/4); hold φ 4.4mm is recorded as T-1 (1/4).
High directivity: generally, it is a pointed epoxy package, or a package with a metal reflection cavity, without scattering agent. The half-value angle is 5 ° - 20 ° or less, with high directivity, which can be used as local lighting source or combined with light detector to form an automatic detection system;
