Description

一种石墨烯电极的超级电容器
技术领域
本实用新型属于电容器技术领域，具体涉及一种石墨烯电极的超级电容器。
背景技术
Li离子、NiMH等新型电池可以提供一个可靠的能量储存方案，并且已经在很多领域中广泛使用。众所周知，化学电池是通过电化学反应，产生法拉第电荷转移来储存电荷的，使用寿命较短，并且受温度影响较大，这也同样是采用铅酸电池（蓄电池）的设计者所面临的困难。同时，大电流会直接影响这些电池的寿命，因此，对于要求长寿命、高可靠性的某些应用，这些基于化学反应的电池就显出种种不足。
超级电容器中影响其容量的决定因素是电极材料。现有的超级电容器中电极材料主要有：活性炭系列和过渡金属氧化物系列。活性炭系列的材料导电性较差，作为电容器的电极等效串联电阻大。而且该活性炭系列的比表面积实际利用率不超过30%，电解质离子难以进入。过渡金属氧化物用作电极材料在提高超级电容器的容量方面具有良好的效果，但其成本太高，无法推广使用。
实用新型内容
本实用新型所要解决的技术问题在于针对上述现有技术中的不足，提供一种石墨烯电极的超级电容器。该超级电容器具有能量密度大和比充电电池功率密度高的优点,而且可快速充放电，使用寿命长,有很宽的电压和工作温度范围，是一种新型、高效、实用的能量存储装置。
为解决上述技术问题，本实用新型采用的技术方案是：一种石墨烯电极的超级电容器，包括外壳，其特征在于，所述外壳内设置有两个与外壳侧壁平行的石墨烯电极，两个所述石墨烯电极之间填充有电解质，两个所述石墨烯电极之间设置有隔膜，所述石墨烯电极的端部设置有引线，所述引线穿出外壳与设置于外壳上方的引脚相连接。
上述的一种石墨烯电极的超级电容器，所述隔膜与石墨烯电极平行设置。
上述的一种石墨烯电极的超级电容器，所述隔膜位于两个石墨烯电极的中间位置。
本实用新型与现有技术相比具有以下优点：
1、本实用新型的超级电容器具有能量密度大和比充电电池功率密度高的优点,而且可快速充放电，使用寿命长,有很宽的电压和工作温度范围。
2、本实用新型的超级电容器是一种新型、高效、实用的能量存储装置。
下面通过附图和实施例，对本实用新型的技术方案做进一步的详细描述。
附图说明
图1为本实用新型的超级电容器的结构示意图。
附图标记说明:
1—外壳；      2—石墨烯电极；      3—电解质；
4—隔膜；      5—引线；            6—引脚。
具体实施方式
如图1所示，本实用新型石墨烯电极的超级电容器，包括外壳1，所述外壳1内设置有两个与外壳1侧壁平行的石墨烯电极2，两个所述石墨烯电极2之间填充有电解质3，两个所述石墨烯电极2之间设置有隔膜4，所述石墨烯电极2的端部设置有引线5，所述引线5穿出外壳1与设置于外壳1上方的引脚6相连接。
本实施例中，所述隔膜4与石墨烯电极2平行设置。
本实施例中，所述隔膜4位于两个石墨烯电极2的中间位置。
本实用新型的超级电容器的工作过程为：通过引脚6连接外部电源的正、负极，通过引线5使得相对的两个石墨烯电极2上分别聚集正、负电子，电解质3中的正、负离子由于电场作用分别聚集到与石墨烯电极2正负极板相对的界面上，从而形成双集电层，可以进行快速充电，储电量多而且寿命长。
以上所述，仅是本实用新型的较佳实施例，并非对本实用新型作任何限制，凡是根据本实用新型技术实质对以上实施例所作的任何简单修改、变更以及等效结构变化，均仍属于本实用新型技术方案的保护范围内。
