Engineers use MoS2 nano "sandwich" to improve rechargeable batteries

Singer and his team discovered that molybdenum dishulfide flakes store two times as much lithium as previous research. Singer added that the battery’s high lithium potential does not hold for very long. The flakes will eventually run out of lithium after 5 charges. Singer has previously stated this behaviour is similar to that of a lithium-sulfur lithium-sulfur lithium battery. There is a well-known fact that sulfur makes intermediate polysulfides, which are then dissolved in the electrolyte. This results in volume fading. It is believed that the lower molybdenum dioxide sheet capacitance may also result from the electrolyte’s reduction of sulfur. For the purpose of reducing the dissolution of the sulfur-based product in the electrolyte the researchers wrapped the molybdenum dishulfide sheet within a silicon carbonitride layer. Or, in the SiCN-ceramic layer. Singh explained that ceramics are high-temperature, glass-like materials. These are produced by heating liquid silicone-based polymers. Singer said that the silica carbonitride-coated molybdenum dioxide sheet has a stable cycle in lithium ions. Singer was not sure if it was a standard copper foil battery or an elastic flexible paper battery. Singer, his team and others also examined the cells with an electron microscope. They found that silicon carbitride has the ability to prevent the chemical and mechanical breakdown of organic liquid electrolytes. Singer now hopes to be able better understand the molybdenum dioxide battery for everyday use. Electronic devices such as smartphones can be charged up to hundreds of times. Researchers will continue testing battery molybdenum sulfide cells during charging cycles to gain more insight and improve the rechargeability of batteries.
