[第一實施例][First Embodiment]
配合圖1至圖5所示,本發明第一實施例提供一種捲繞型電解電容器封裝結構Z,其包括:一捲繞型電容器1、一封裝結構2、一第一導電接腳3以及一第二導電接腳4。As shown in FIGS. 1 to 5, the first embodiment of the present invention provides a winding type electrolytic capacitor packaging structure Z, which includes: a
首先,如圖1所示,捲繞型電容器1包括一捲繞式正極箔片11、一捲繞式抗腐蝕負極箔片12以及兩個捲繞式絕緣隔離紙13。更進一步來說,兩個捲繞式絕緣隔離紙13的其中之一設置在捲繞式正極箔片11與捲繞式抗腐蝕負極箔片12兩者之間,並且捲繞式正極箔片11與捲繞式抗腐蝕負極箔片12兩者其中之一設置在兩個捲繞式絕緣隔離紙13之間。舉例來說,如圖1所示,捲繞式正極箔片11是設置在兩個捲繞式絕緣隔離紙13之間。另外,捲繞式絕緣隔離紙13可為一種通過含浸方式以附著有電解液溶液的隔離紙或者紙製箔片。然而,本發明不以上述所舉出的例子為限。First, as shown in FIG. 1, the
再者,配合圖1與圖2所示,捲繞型電容器1會被容置在封裝結構2內。舉例來說,封裝結構2包括一殼體結構20(例如鋁殼或者其它金屬殼體),然而本發明不以此舉例為限。此外,第一導電接腳3包括被容置在封裝結構2的內部的一第一內埋部31以及裸露在封裝結構2的外部的一第一裸露部32,並且第一導電接腳3電性接觸捲繞式正極箔片11與捲繞式抗腐蝕負極箔片12兩者之中的其中一個。另外,第二導電接腳4包括被容置在封裝結構2的內部的一第二內埋部41以及裸露在封裝結構2的外部的一第二裸露部42,並且第二導電接腳4電性接觸捲繞式正極箔片11與捲繞式抗腐蝕負極箔片12兩者之中的另外一個。Furthermore, as shown in FIG. 1 and FIG. 2, the
此外,配合圖3至圖5所示,捲繞式抗腐蝕負極箔片12包括一導電基底120、兩個含鋅材料層121以及兩個導電化合物層122。兩個含鋅材料層121分別設置在導電基底120的兩相反表面上,以分別接觸導電基底120的兩相反表面。兩個導電化合物層122分別設置在兩個含鋅材料層121上,以分別接觸兩個含鋅材料層121。舉例來說,捲繞式抗腐蝕負極箔片12的厚度小於或者等於50µm,並且形成在捲繞式抗腐蝕負極箔片12上的導電化合物層122的厚度可介於10 nm至2000 nm之間(另一較佳的厚度範圍為10 nm至500 nm之間)。另外,導電基底120的兩個表面都可以是由機械加工(例如滾壓、壓印等方式)所形成的粗糙化表面12000,並且粗糙化表面12000的粗糙度可以小於或者等於50 µm。藉此,由於透過粗糙化表面12000的形成而增加導電基底120的表面積,使得含鋅材料層121附著在導電基底120的附著強度也能被提升,所以含鋅材料層121不容易脫離導電基底120,以有效提升捲繞式抗腐蝕負極箔片12的可靠度(也就是提升含鋅材料層121附著在導電基底120上的附著度)。然而,本發明不以上述所舉出的例子為限。In addition, as shown in FIGS. 3 to 5, the wound anticorrosive
另外,如圖4或者圖5所示,導電基底120可為Al材料,並且導電基底120沒有氧化層且沒有腐蝕層。也就是說,當導電基底120尚未被氧化前,兩個含鋅材料層121可以預先分別設置在導電基底120的兩個粗糙化表面12000上。舉例來說,含鋅材料層121可為一純鋅材料層或者一鋅合金材料層。另外,經過一“結構強度測試機”進行結構強度測試後(或者經過一結構剛度測試機進行結構剛度測試後),含鋅材料層121的結構強度(或者結構剛度)會大於導電化合物層122的結構強度(或者結構剛度),並且導電化合物層122的結構強度(或者結構剛度)會大於導電基底120的結構強度(或者結構剛度)。此外,經過一“導電率測試機”進行導電率測試後,導電基底120的導電率(導電性)會大於含鋅材料層121的導電率,並且含鋅材料層121的導電率會大於導電化合物層122的導電率。再者,經過一“黏著力測試機(例如百格測試器(cross-cut adhesion tester))”進行黏著力測試後,含鋅材料層121與導電基底120兩者之間的黏著力(附著度)以及含鋅材料層121與導電化合物層122兩者之間的黏著力都會大於“製作導電基底120所使用的導電材料”與“製作導電化合物層122所使用的導電材料”兩種材料之間的黏著力(也就是說,當導電基底120與導電化合物層122相互連接時,導電基底120與導電化合物層122之間的黏著力)。藉此,捲繞式抗腐蝕負極箔片12的整體結構強度(或者整體結構剛度)可以透過含鋅材料層121的使用而得到提升。值得注意的是,捲繞式抗腐蝕負極箔片12可選用一經過退火的負極箔片或者一未經退火的負極箔片。然而,本發明不以上述所舉出的例子為限。In addition, as shown in FIG. 4 or FIG. 5, the
舉例來說,導電化合物層122可為厚度介於10 nm至2000 nm之間的一電解液溶液阻隔層,以用於防止導電基底120(或者含鋅材料層121)被電解液溶液所接觸而受到腐蝕,所以導電基底120(或者含鋅材料層121)的厚度可以透過導電化合物層122的保護而不會改變。也就是說,由於導電基底120(或者含鋅材料層121)可以透過導電化合物層122的保護而不會受到電解液溶液的腐蝕而降低原有的厚度,所以本發明所使用的導電化合物層122的厚度即使只有10 nm,導電基底120還是可以透過導電化合物層122的保護而不會被電解液溶液所腐蝕而降低原有的厚度,以使得捲繞式抗腐蝕負極箔片12依然能夠保持能夠滿足後續加工條件的結構強度。然而,本發明不以上述所舉出的例子為限。For example, the
舉例來說,導電化合物層122可為一氮化物層、一碳化物層、一碳氮化物層、一氮氧化物層以及一碳氧化物層之中的至少一者。然而,本發明不以上述所舉出的例子為限。For example, the
更進一步來說,當導電化合物層122為氮化物層時,氮化物層至少由氮化物(nitride)所製成,並且氮化物可選自於由氮化矽(Si3N4)、氮化鈦(TiN)、氮化鋁(AlN)、氮化鈦鋁((Ti,Al)N)、氮化鉻(CrN)、氮化鉬(MoN)、氮化鎢(WN)以及氮化鉭(TaN)所組成的群組。然而,本發明不以上述所舉出的例子為限。Furthermore, when the
更進一步來說,當導電化合物層122為碳化物層時,碳化物層至少由碳化物(carbide)所製成,且碳化物可選自於由碳化鈦(TiC)、碳化鋁(AlC)、碳化鉻(CrC)、碳化鉬(MoC)、碳化鎢(WC)以及碳化鉭(TaC)所組成的群組。然而,本發明不以上述所舉出的例子為限。Furthermore, when the

值得注意的是,不管是“導電基底120沒有氧化層且沒有腐蝕層(第一實施例)”或者是“導電基底120有氧化層1200而無腐蝕層(第二實施例)”,捲繞式抗腐蝕負極箔片12的整體結構強度(或者整體結構剛度)可以透過含鋅材料層121的使用而得到提升。另外,導電化合物層122可以用於防止導電基底120(或者含鋅材料層121)被電解液溶液所接觸而受到腐蝕,所以導電基底120(或者含鋅材料層121)的厚度可以透過導電化合物層122的保護而不會改變(也就是說,導電基底120(或者含鋅材料層121)可以透過導電化合物層122的保護而不會被電解液溶液所腐蝕而降低原有的厚度),以使得捲繞式抗腐蝕負極箔片12依然能夠保持能夠滿足後續加工條件的結構強度。It is worth noting that whether it is "the
