基于尖晶石正极材料的柔性锂离子电池的制备和测试

Preparation and testing of flexible lithium ion batteries based on spinel cathode materials

发展了一种新颖、简单且普适性很强的制备柔性无支撑的电极薄膜方法,并成功地组装和测试了LiMn2O4/Li4Ti5O12,LiNi0.5Mn1.5O4/Li4Ti5O12以及LiNi0.5Mn1.5O4/石墨3种全电池.以这种方法制备的锂离子电池具有能量密度高的特点,在某些特定的领域具有潜在的应用前景.此外,这种技术还有可能应用于锂离子电池的原位光谱分析.

A novel, simple and universal technique to fabricate flexible and freestanding electrode films was introduced. Three types of lithium ion batteries LiMn2O4/Li4Ti5O12, LiNi0.5 Mn1.5 O4/Li4TisO12 and LiNi0 5Mn1.5 O4/graphite were assembled and tested. Lithium ion batteries fabricated using this method have high energy density and potential applications in some special areas. In addition, this technique mayalso be applied to in-situ spectroscopic research of lithium ion batteries.
