aTwo possible paths of Li+ transport in PEO-passive fillers composite. b Three possible paths of Li+ transport in PEO-active fillers composite. c Passive fillers’ effect of distorting the regularity of PEO, which lead to the inhibition of recrystallization. d Lewis acid–base interaction on PEO-ceramic interfaces, including Al-X−, Al-O, O-Li+, Li+-X−. e Long continuous express path of Li+ provided by ceramic nanowires compared with discontinuous transport path of Li+ provided by ceramic nanoparticles
