Description
技术领域
本发明涉及一种电池结构,尤指一种具有保护隔离结构的锂电池。
背景技术
可携式电子产品在譬如为如医疗、娱乐等产业广泛使用,于此些产业中,可携式电子产品都需具备轻量、可携以及多样化,在这些电子产品中使用的电池,则要求根据可携式电子产品来设计,使其外观匹配于可携式电子产品,譬如为外包装尺寸、形状等;因此,柔性电池的可挠曲特性扮演相当重要的角色。图1为常见的柔性锂电池的横截面图,如图1中所示,柔性锂电池10主要包括上集电层12、下集电层14、以及设置在上集电层12与下集电层14之间的外封装16,上集电层12、下集电层14以及外封装16形成封围空间18;第一活性材料层20、间隔层22与第二活性材料层24设于此封围空间18来形成电化学系统层,第一活性材料20接触于上集电层12、第二活性材料层24接触于下集电层14,此种柔性锂电池10的特性为整体是可以动态弯曲。
此外,在锂电池的结构设计中,阴极的水平面的面积必须小于阳极的水平面的面积,以避免当阴极释放超出阳极可容许的锂离子时,过度的锂析出而形成锂枝晶。这些锂枝晶会穿透间隔层而导致电池短路。目前解决此问题的方法是于制程中控制阴极与负极的水平面的面积,但却没有其他的方法能再重复验证。
为了克服上述问题,本发明提供一种电池结构,以解决前述现有技术的问题。
发明内容
本发明的主要目的是提供一种电池结构,其使用第一塑框以覆盖间隔层的一部分区域,其对应于第一活性材料层与第二活性材料层以维持锂电池的A/C比,并且减少形成锂枝晶的可能性和程度。
为达到上述目的,本发明提供了一种电池结构,电池结构包括第一集电层、第一活性材料层、间隔层、第一塑框、第二活性材料层以及第二集电层,第一活性材料层设置在第一集电层上,间隔层设置于第一活性材料上,并完全覆盖于第一活性材料层的顶面。第一塑框设置于间隔层的侧壁,且第一塑框的顶部具有延伸到间隔件顶面的突出部,第二活性材料层设置在间隔层与突出部上,并透过间隔层和突出部而与第一活性材料隔离;第二集电层设置在第二活性材料层上。
下面藉由具体实施例详加说明,当更容易了解本发明的目的、技术内容、特点及其所达成的功效。

图2是本发明电池结构的局部剖面示意图;
图3是本发明电池结构的局部剖面的另一示意图;
图4是本发明电池结构的剖面示意图;
图5是本发明电池结构的剖面示意图;

图8是本发明电池结构的局部剖面的另一示意图。
具体实施方式
请参阅图2,其为本发明电池结构的部分剖视图。锂电池30包括第一集电层32、第一活性材料层34、间隔层36以及塑框38,第一活性材料层34设置于第一集电层32上,第一活性材料层34的水平面区域小于第一电流收集层32,而使得部分的第一集电层32可外露于第一活性材料层34;间隔层36设置于第一活性材料层34上,并且完全覆盖于第一活性材料层34的顶面。塑框38设置在间隔层36的侧壁上并延伸至间隔层36的顶面以形成突出部381,间隔层36不与第一活性材料层34接触的角落受到塑框38的覆盖。
此外,覆盖于间隔层36侧壁的塑框38的部分会延伸到第一活性材料层34的侧壁,例如,覆盖于间隔层36侧壁的塑框38的部分会向下延伸,而完全覆盖于第一活性材料层34的侧壁,如图3所示。
如图4所示,本发明的电池结构还包含有第二活性材料层40、第二集电层42、以及第二塑框46,第二活性材料层40位于间隔层36和突出部381表面,第二活性材料层40藉由间隔层36和突出部381而与第一活性材料层34隔离。第二集电层42设置于第二活性材料层40上,第二塑框46顶面设置于第二集电层42,且封围于第二活性材料层40周缘,第二塑框46底面连于第一塑框38,更具体地,第二塑框46的底面是直接与第一塑框38的突出部381直接接触。
一般的电池设计中,阳极/阴极比率通常是通过化学配方、电极的涂布区域或涂布密度来加以控制,从而减少形成锂枝晶的可能性和程度。然而,除了上述的解决方案之外,本发明使用突出部381来遮闭第一活性材料层来控制A/C比率,并保持安全性和电气性能。
除了上述所言,第一塑框38的突出部381延伸至间隔层36的顶面边缘,以改善锂电池30结构稳定性,举例来说,于柔性电池中,间隔层36再经过弯曲后,通常会呈现弯曲或变形,并且甚至会引起内部短。然而,不管是聚合物间隔层、具有特殊效果涂层的聚合物间隔层或是陶瓷间隔层,当突出部381延伸至间隔层36顶面的边缘时,即可有效维持间隔层36与第一活性材料层34或是间隔层36与第二活性材料层40之间的接触,并且可防止间隔层36边缘的变形;突出部381可有效提升间隔层36的顶面边缘的结构性强度,特别是应用在陶瓷间隔层。
此外,在上述结构中,第一塑框的突出部分381和间隔层36形成一种新的混合隔离结构,来将第二活性材料层40与第一活性材料层34隔离,进一步来说,第一集电层32或第二集电层42可以是电路板的导电表面。
另外,第一集电层32和/或第二集电层42的外表面更具有保护层50,保护层50可以防止外部环境与第一集电层32以及/或第二集电层42之间的接触,保护层50可于锂电池30弯曲过程中,保护第一集电层32和/或第二集电层42的破裂。
请参考图5,锂电池30包装于铝箔袋44中,铝箔袋44可以防止电解质的泄漏以及阻挡外部环境中的水分和氧气。
请参考图6,其绘示本发明另一电池结构,锂电池30更包含第三塑框48,第二塑框46底部连接至第三塑框48的顶部,第三塑框48的底部连接到第一塑框38的顶部。第一塑框38和第二塑框46具有比第三塑框48的更好的异质表面的黏着力,第三塑框48具有第一塑框38、第二塑框46与第三塑框48中最好的均匀表面黏着力,第三塑框48会将第一塑框38与第二塑框46紧密地接合。
进一步而言,第一塑框38、第二塑框46、第三塑框48与保护层50可以进一步覆盖第一集电层32和第二集电层42的边缘,于锂电池30弯曲过程中,第一集电层32与第二集电层42接触所引起的外部短路的情况,可以透过第一塑框38、第二塑框46、第三塑框48以及保护层50的绝缘特性来加以减少;保护层50可以不同的结构涂覆第一集电层32以及第二集电层42的边缘,主要取决于电池的设计或制程需求。保护层50可以是单层涂布或多层涂布。
请参照图7,其为本发明电池结构体的另一局部示意图。图7与图2的差别在于,间隔层还进一步延伸到第一活性材料层的侧壁上。
请参照图8,其为本发明的电池结构体的另一局部示意图。图8与图3的差别在于,间隔层还进一步延伸到第一活性材料层的侧壁上。
第一塑框38、第二塑框46、第三塑框48和保护层50的材料可选自于譬如聚酰亚胺(polyimide)、环氧树脂(epoxy)、压克力树脂(acrylic resin)以及硅胶等绝缘聚合物,间隔层36的材料选自聚合物材料、陶瓷材料、玻璃陶瓷材料或玻璃纤维。第一活性材料层34、第二材料层40和间隔层36会吸收电解质,电解质是液体电解质、胶态电解质或固态电解质。
综合前述,锂电池的A/C比率可以藉由第一塑框的突起而被有效地控制,以减少形成锂枝晶的可能性和程度。
唯以上所述者,仅为本发明的较佳实施例而已,并非用来限定本发明实施的范围。故即凡依本发明申请范围所述的特征及精神所为的均等变化或修饰,均应包括于本发明的申请专利范围内。
