All-solid-state batteries(ASSBs) have attracted considerableattention due to the expectation that they can overcome major problemssuch as thermal instability and limited energy density of the presentlithium-ion batteries based on liquid electrolyte. Solid electrolytes can generallybe divided into two types, which are sulfide-based SEs and non-sulfide-basedSEs (oxide-based and phosphate-based) depending on their characteristic andcrystal structure. In this talk, we provide the performance improvementstrategy of the composite cathodes applied to each type of SEs. In the firstpart, regarding the sulfide SEs, we will present the results of comparativeanalysis on chemical and electrochemical stability between the compositecathodes to which different types of SEs are applied. In the second part,regarding the non-sulfide SEs, we will present the correlation between particlesize of SE and the electrochemical properties of the composite cathode. |
