Singer and his team discovered that molybdenum dishulfide flakes store two times as much lithium as previous research. Singer added that they found the battery’s high lithium potential does not hold for very long. The flakes will eventually run out of lithium after 5 charges. Singer said it is almost like a lithium-sulfur lithium battery. That uses sulfur to its electrodes. 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 loss in sulfur in electrolyte. For the purpose of reducing the sulfur-based product dissolution, researchers wrapped the molybdenum dish in silicon carbonitride. Or, in the SiCN-ceramic layer. Singh explained that ceramics are high-temperature, glass-like materials. They can be prepared using liquid silicon-based plasticmers.
Singer stated after the reaction that the silicon carbonitride coated molybdenum dioxide sheet showed a stable cycle in lithium ions. 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 sulfide battery for daily 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.
