All-solid-state rechargeable thin film lithium batteries with LixMn2O4 and LixMn2O4–0.5ZrO2 cathodes

Nano-sized copper tungstate thin films as positive electrodes for rechargeable Li batteries

“…In fact, radio frequency (R.F.) sputtering is a promising PVD technique to fabricate nano-dimensional thin-film electrode materials [17,18], which perhaps exhibit better electrochemical performance and unexpected reactive path as compared with traditional bulk powder materials.…”

Sputtered Al-doped lithium manganese oxide films for the cathode of lithium ion battery: The post-deposition annealing temperature effect

“…As a result, many attempts have been made to improve structural stability and cycleability of thin LiMn 2 O 4 film by optimization of deposition parameters or doping. Recently, Li and Fu reported that addition of ZrO 2 to LiMn 2 O 4 film could overcome the disadvantage of two distinct voltages in 3 V and 4 V regions [26]. Ogumi and co-workers reported that lithium-ion excess Li 1 In this work, lithium-excess Al-doped lithium manganese oxide films were prepared by R.F.…”

“…LiMn 2 O 4 in thin film form, prepared by either PVD or solutionderiving methods [19][20][21][22][23][24][25][26][27][28][29], is widely considered as a promising cathode material for all-solid-state thin film battery, which can be used as an integrated and self-sustained power source for MEMS devices, micro-sensors, smart cards and nonvolatile memory chips. The electrochemical properties of thin LiMn 2 O 4 film were found to vary significantly with preparation conditions.…”

Synthesis and electrochemical properties of Li[Ni x Co y Mn1−x−y ]O2(x, y = 2/8, 3/8) cathode materials for lithium ion batteries

“…However, the toxicity and high cost of cobalt represent some of the problems of this material. Thus, extensive research has been carried out to find alternative positive electrode materials such as LiFePO 4 [1][2] and LiMn 2 O 4 [3][4].…”
