项目摘要

The preparation procedure of manganese oxide films have been investigated from 2005 through 2006. Before starting this research, it was found that manganese oxide (Mn_3O_4) films for lithium secondary batteries have been prepared using a reactive evaporation method. The metallic Mn in the crucible suffers oxidation since it is evaporated in the oxygen atmosphere. So the deposition rate is deteriorated with increasing deposition run.This research shows a technique which keeps off the Mn evaporant from oxygen atmosphere during the reactive evaporation process. Three types of separators have been developed through our studies: a Mo separator, a stainless steel cell (SUS cell), and a quartz ampoule. They have been installed in the bottom of the Mn crucible. The Mn_3O_4 films could be prepared with high reproducibility with these devices.During the evaluation of Mn_3O_4 films, it was found that manganese oxide films which involve Li have to be prepared. Preparation of LiMn_2O_4 thin films using a sputtering method was started on 2006. It was found that LiMn_2O_4 thin films could be prepared even at the substrate temperature of room temperature (R.T.) by this method. This material is superior to other materials in the cost performance as well as non-toxic. The crystal properties could be improved after a rapid thermal annealing (RTA) process. The preparation procedure has been sophisticated through this study. The study is now under way.

从2005年到2006年，我们研究了锰氧化物薄膜的制备过程。在开始这项研究之前，人们发现锂二次电池用锰氧化物（Mn_3O_4）薄膜是用反应蒸发法制备的。坩埚中的金属Mn由于在氧气氛中蒸发而遭受氧化。本研究提出了一种在反应蒸发过程中将锰蒸发液与氧气隔离的技术。通过我们的研究开发了三种类型的分离器：Mo分离器，不锈钢电池（SUS电池）和石英电池。它们已经安装在锰坩埚的底部。在对Mn_3O_4薄膜的评价过程中发现，必须制备含有Li的氧化锰薄膜。LiMn_2O_4薄膜的溅射法制备始于2006年。结果表明，在室温（R.T.）通过这种方法。该材料具有上级的性能价格比，无毒。经过快速热退火（RTA）处理后，晶体性能得到改善。通过本研究，制备程序已经复杂化。这项研究目前正在进行之中。
