摘要：

Thin films of LiM(2)O(4) spinel were fabricated by r.f. magnetron sputtering. The fresh films were amorphous but could be crystallized into a spinel structure by rapid thermal annealing in an oxygen ambient. The electrochemical performance of LiMn,O, thin-film cathode was tested in LiMn2O4 thin-film (2000 Angstrom)/1 M LiClO4 in propylene carbonate(+) dimethoxyethane/Li metal arrangements. LiMn2O4 spinel films prepared at 750 degrees C had a favorable structure and grains for lithium-ion intercalation. Room temperature cycling of these films showed good intercalation kinetics and very promising cycling behavior.
