As a result, a strategy to reduce the proportion of LEs in the battery (a hybrid-solid–liquid battery or quasi-solid-state battery, quasi-SSB) is proposed, so that the electrochemical and safety performances can be balanced. [ 25] Quasi-SSBs and ASSBs can be collectively referred to as SSBs.
One of the approaches to address above mentioned challenges is the use of quasi-solid-state electrolyte (QSSE) in Li–S batteries, that is, adding minimum amount of the liquid electrolytes (organic solvents or ionic liquid) into the solid electrolytes (polymer or inorganic material) as seen in Fig. 1 a.
