摘要：

The effect of the particle sizes of LiNi1/3Co1/3Mn1/3O2 and Li2S-P2S5 solid electrolytes (SEs) on the electrode morphology was investigated. Smaller-sized SE particles were advantageous in fabricating dense and homogeneous electrode layers with an effective lithium-ion conduction pathway and a large electrode-electrolyte interfacial contact area because of the unique mechanical properties of sulfide-based SEs. The homogeneous distribution of the SE is also effective in the suppression of cracking and fracturing of LiNi1/3Co1/3Mn1/3O2 because of the favorable mechanical properties of the sulfide-based SEs. The capacity of the all-solid-state cells under high rate operation was thus remarkably improved. (C) 2015 Elsevier B.V. All rights reserved.
