• Learn lithium sulfur battery research status and progress

  Compared with the traditional lithium ion battery, the theoretical energy density of lithium sulfur battery​ can reach 2680Wh/kg at the average voltage of 2.15V, which is about 6 times of the energy density of the current lithium ion battery. Therefore, it is considered as one of the most potential systems to replace the traditional lithium ion battery.

• Learn cesium metal features and application fields

  The word "cesium" may sound strange to you. In fact, cesium is a metallic element that can be used in everyday life, such as television sets -- it is used in photocells -- because of its valuable and excellent photoelectric properties, namely, the release of electrons when exposed to light. The cesium metal is sprayed on the silver sheet to make a variety of photocells.

• Molybdenum disulfide light absorption study via plasma nanostructures

  When molybdenum disulfide met light about two years ago, MIT scientists began investigating the potential of molybdenum disulfide (MoS2) as a photovoltaic material. The result was a bit of a mess. They concluded that the conversion efficiency of the material was very low, but another encouraging finding was that by squeezing three pieces of molybdenum disulfide down to a nanometer thick, the material could absorb 10% of direct sunlight.
