Tetrahydrothiophene is a sulfur-containing saturated heterocyclic compound obtained by catalytic hydrogenation of thiophene. After thiophene is reduced to tetrahydrothiophene, it no longer has a conjugated system and aromaticity. Therefore, tetrahydrothiophene shows the properties of general thioethers. Easily oxidized to sulfoxides and sulfones. Tetrahydrothiophene can be used as a raw material for the production of pharmaceuticals, pesticides and photochemicals.
Lithium-ion batteries (Li-ion batteries) are widely used in portable electronic devices, electric vehicles, and renewable energy storage systems due to their high energy density and long cycle life. These batteries are composed of several key materials such as cathode materials, anode materials, electrolyte, separator and current collector, which enable them to operate. Other minor components in Li-ion batteries include binders, additives, and fillers, which improve electrode stability, electrolyte performance, and battery safety. Ongoing research and development focus on improving the energy density, safety, and cost-effectiveness of Li-ion batteries through advancements in materials, including the exploration of new cathode and anode materials, solid-state electrolytes, high-voltage electrolyte additives, and advanced manufacturing techniques.
