▎ 摘　　要

NOVELTY - A lithium-sulfur electrochemical cell (100) comprises a cathode (110) including porous regions each defined by two or more core-shell structures adjacent to and in contact with each other, an anode (120) positioned opposite to the cathode, and an electrolyte (130) comprising a ternary solvent package and 2-mercaptobenzothiazole, which is interspersed throughout the cathode, and which is in contact with the anode. USE - Lithium-sulfur electrochemical cell e.g. lithium-ion battery or lithium-sulfur battery is used for electronic device. Uses include but are not limited to mobile phone, laptop, consumer electronics, electric vehicle, factory, and building. ADVANTAGE - The lithium-sulfur electrochemical cell has high energy density, and improved performance, energy capacity, cycle characteristics, rate capability, long-term stability, safety and lifespan characteristics.
