Study on the regulation mechanism of a coral-like Li 7 La 3 Zr 2 O 12 inorganic filler on the properties of poly(ethylene oxide)-based composite solid electrolytes

Multi-physical field simulation and Raman results show that Li + ions mainly migrate in the interior of LLZO. A Li + -migration channel is also formed at the PEO/LLZO interface due to the large interfacial contact area.
