Abstract

本发明属电化学领域。一种全固态蓄电池，阳极采用锂材料，阴极采用具有尖晶石结构的二氧化锰材料，电解质采用有机锂蒙脱石等。该蓄电池可以深度多次充放电，具有良好的电性能，而且重量轻，体积小，使用方便。

Description

本发明    属电化学领域，是一种蓄电池。
目前通常的蓄电池有铅酸蓄电池和镍镉电池。前者重量大、比能量小;后者电性能较好，但都不是全固态，使用时液体电解质容易流出。给使用造成一定的局限性。
本发明    的目的是提供一种电性能好、重量轻的全固态蓄电池。
本发明 包括阳极、阴极、电解质、外壳几个部分。图1为其结构示意图。其中阳极1采用锂（Li）材料，阴极2采用具有尖晶石结构的二氧化锰（Li〔Mn2〕O4）材料;电解质3采用有机锂蒙脱石或聚环氧乙烯高氯酸锂（PEO8·LiClO4），或其它离子导电物。上述的阳极1由锂压在镍集电网上构成;上述的阴极2由Li〔Mn2〕O4与乙炔黑、聚四氟乙烯混合压在镍集电网上构成，其混合的比例与工艺和常规的蓄电池阴极制作类同;上述电解质3为固态，因而又兼作隔膜，省去了采用液体电解质时所需的隔膜材料。将上述阳极1、阴极2、固态电解质3按常规工艺封接在外壳4内，即得全固态锂尖晶石结构的二氧化锰蓄电池。
本发明 的阴极材料-尖晶石结构的二氧化锰（Li（Mn2）O4）是锂在二氧化锰中的嵌入化合物（简称嵌合物（Intercalation Compound）），是一种良好的贮能材料，其X-线衍射图谱如图3所示，其特征峰列表如下：
本蓄电池充放电的机理如下：放电，锂“嵌入”尖晶石结构的二氧化锰的晶格;充电，锂从晶格中“脱嵌”出来，如是“嵌入”与“脱嵌”往复循环，达到贮能目的。本蓄电池可以深度多次充放，（其充放次数可与镍镉电池相比）而阴极材料结构未发生变化。所以本蓄电池具有良好的电性能，而且重量轻，体积小，使用方便，电解质不会外流。
实施例，按图1所示结构，用常规工艺制作蓄电池，其开路电压为3.4伏，以500μA/cm放电，工作电压为2.7伏，可深度多次充放。图2为其第十次循环的充放电曲线图，其中曲线a为0.5mA/cm放电曲线，b为0.25mA/cm充电曲线;
图1为本蓄电池的结构示意图。
图2为本蓄电池第十次循环的充放曲线图。
图3为本蓄电池阴极材料Li〔Mn2〕O4X-线衍射图谱。
