The charge-discharge performances for lithium ion batteries using the PLD thin-film cathodes of LiNi0.8Co0.2O2, LiFePO4 and LiMn2O4 were investigated. LiMn2O4 and LiFePO4, which have a 3-D frame work crystal structure, showed smooth charging and discharging. On the contrary, LiNi0.8Co0.2O2, which consists of a 2-D layered crystal structure, exhibited a poor discharge capacity. The differences in electro-chemical behaviors might be related to characteristics of PLD thin-film such as high crystallinity or high degree of preferred orientation. Furthermore, the surface roughness and film thickness of LiMn2O4 thin-film were varied by using SPT and PLO method, and their structures were clarified by XRD and SEM. The SPT method gave the film with rough and large surface area, while the PLD method provided a flat and high crystalline film. Their rate performances of charge and discharge were independent of the deposition method but depended on the film thickness. Optimum performance was obtained with the PLO film deposited for 30 min, which showed almost the same shape of the discharge curve between 36 C and 720 C. (C) 2008 Elsevier B.V. All rights reserved.
