Description
530433 五、發明説明（1 ) 本發明係關於一種電池（例如鋰離子電池）之製造方 法，其爲將眾多的陽極及陰極板堆疊在一起。 多年來已熟知以鋰金屬陽極及可內插或嵌入鋰離子 之材料的陰極來製造電池。許多廣泛不同的內插材料 (諸如氧化鋰鈷及氧化鋰錳）已熟知可做爲陰極材料，及 此材料可與固體電解質材料混合以形成複合陰極。此 電池可使用諸如飽含做爲電解質之鋰鹽溶液的濾紙_ 聚丙烯做爲分離器，其中該鋰鹽溶液劑爲諸如碳酸丙二 酯之有機液體。此外，可使用以聚合物爲基底的固體_ 解質，例如鋰鹽與聚（環氧乙烷）之復合物。於二級或可 再充電的鋰電池實例中，鋰金屬陽極之使用因其會產生 樹模石生長的問題而未令人滿意；但若使用內插材料 (諸如石墨）做爲陽極則可製得令人滿意的電池。此電 池可稱爲”鋰離子”電池或”轉換”電池，其中鋰離子在充 電及放電期間會在二個內插材料之間交換。 例如，已由哥日次（Gozdz)等人（美國5296318)建議使 用以聚偏二氟乙烯及相關的共聚物爲基底之聚合物電 解質，其可利用將75至92個百分比的偏二氟乙烯及8 至2 5個百分比的六氟丙烯共聚物，與鋰鹽及相容的溶 齊U (諸如碳酸次乙酯/碳酸丙二酯混合物）混合，再從含低 沸點溶齊！J (諸如四氫呋喃）之溶液澆鑄（cast)。 G B 2 3 〇 9 7 0 3 B ( A E A技術）描述類似的電解質組成物，其中 該聚合物爲聚偏二氟乙烯（PVdF)同聚合物，而PVdF的 特徵爲其具有非常低的熔體流動指數。亦可以下列方 530433 五、發明説明（2 ) 法製造此固體聚合物電解質，首先將聚合物材料製成多 孔薄膜，然後將該薄膜浸入含鋰鹽的有機溶液中使得電 解質溶液聚合物薄膜結合，如描述於E P 0 7 3 0 3 1 6 A ( E 1 f A t o c h e m )。 根據本發明，已提供一種電化學電池的組合方法，其 包括每個具各自的嵌入材料之眾多陽極板及眾多陰極 板，且該方法包括形成交替地堆疊不連續且分離的陰極 板及不連續且分離的陽極皮之堆疊，其中每片板子各自 地包括接至金屬電流收集器的離子嵌入材料層；及在接 續的電極板之間插入形成Z字形的連續分離器/電解質層。 電化學電池可爲鋰離子電池，各自地包含鋰離子嵌入 材料的陽極板及陰極板，例如陽極板中的石墨及陰極板 中的氧化鋰鈷。 分離器/電解質層可爲多孔的惰性分離器，例如聚乙 烯或聚丙烯，及於此實例中電解質溶液必需隨後地加入 組合中以形成電池。例如於鋰離子電池中，此電解質溶 液包括溶解在有機溶劑（諸如碳酸次乙酯）的鋰鹽。此 分離器不會與電解質溶液作用。此外，分離器/電解質 層可包括以P V d F爲基底的多孔聚合物（同聚合物、共 聚物或接枝聚合物）薄片；隨後地加入電解質溶液，該聚 合物薄片會與電解質溶液作用以形成固體或膠質電解 質。再者，另一種分離器/電解質層可包括以PVdF爲基 底的聚合物之聚合物電解質、鋰鹽及相容的有機溶劑 (類似於由哥日次等人在美國5 29 6 318中或AEA技藝 -4- 530433 五、發明説明（3 ) (GB2309703)中所描述）。其中，分離器/電解質層多孔薄 片（較佳地爲多微孔性），其孔洞寬較佳地在0.1及10微 米之間，更佳地在〇. 5及2微米之間。 此多微孔薄膜可從溶劑/非溶劑混合物或助溶劑之澆 鑄獲得，使得全部製程於缺水或缺濕度下進行，以減少 水存在最後的薄膜中之風險（水對鋰電池的特性有 害）。非溶劑不應該僅會溶解在溶劑中，而是應該可與 溶劑以實質上全部的比例溶混。非溶劑之沸點較佳地 比溶劑高，較佳地高於約2 0 °C。例如溶劑可爲二甲基甲 醯胺或二甲基乙醯胺，於此實例中合適的非溶劑有^辛 醇（其可溶解在那些溶劑中及其沸點約1 94t：)。其它非 溶劑有卜庚醇、2 -辛醇、4 -辛醇或3 -壬醇。 於製造多微孔薄膜時，在乾燥期間蒸發速率必需不能 太快，若快速乾燥則會趨向於產生大孔洞，亦會導致形 成不透性薄層而防止下面液體的蒸發。當使用助溶劑 時，乾燥製程應該於溫度低於助溶劑溶解的溫度下進 行。因此聚合物會沉澱及咸信會產生二個相：富含聚合 物相及缺少聚合物相。當助溶劑蒸發時富含聚合物相 之比例會逐漸地增加，但是缺少聚合物相之殘餘的小滴 會形成孔洞。 本發明現將進一步及更特別地僅以實例及參考伴隨 的圖形來描述，而該圖形顯示出本發明之電池的製造 (不按比例）。 冬孔薄膜之製造 530433 五、發明説明（4 ) 將特徵爲具有低的熔體流動指數値（於1 〇公斤及 230 °C下約0.7克/10分鐘）之同聚合物PVdF(Solvay等 級1 0 1 5 )溶解在4 5 °C的二甲基甲醯胺（D M F )中同時攬拌； 將1 5克之Ρ V d F溶解在8 5克的D M F中。然後逐滴加 入小量（9克）的1-辛醇至聚合物溶液，及在此加入期間 小心地混合以保証該混合物爲均相。1 -辛醇的量必需 不能太大否則溶液會膠質化。然後將所產生的三元混 合物使用滾筒上的括刀澆鑄到鋁箔基材上，以形成起始 厚度爲〇 · 2 5毫米的薄層，然後將其通過7公尺長的乾 燥通道，該通道具有二個連續的乾燥區域其各別地爲溫 度65 °C及100 °C。以〇.5公尺/分鐘的速度移動通過乾 燥通道。在乾燥區域將該薄膜曝露至流速爲1 4公尺/ 秒的乾燥空氣中5以蒸發移除任何溶劑及非溶劑。此乾 燥空氣可利用將空氣通過除濕器而獲得。 在薄膜通過乾燥道期間（1 4分鐘），溶劑及非二者逐漸 地蒸發（雖然溫度都低於它們二者的沸點），溶劑趨向於 更快地蒸發。因此可獲得厚度約20-2 5微米的白色聚 合物薄膜，以掃描式電子顯微鏡分析則顯示出其具多微 孔性。洞的直徑尺寸範圍爲〇 . 5 -2 · 0微米，典型地約1 微米。 隨後地將該多微孔薄膜於真空中乾燥以保証移除全 部微量的溶劑及非溶劑。 電極之製造 陰極可從尖晶石L i M n 2 〇 4、小比例的導電碳及做爲 530433 五、發明説明（5 ) 黏著劑之同聚合物p v d F 1 〇 1 5 (如上述所提）的混合物來 製造，而該混合物可從用做P V d F溶劑之N -甲基吡略烷 _ (NMP)溶液中澆鑄而製得。該混合物利用刮刀澆鑄 到鋁箔上，然後通過具溫度爲8 及1 2 (TC的區域之乾 燥器，以保証蒸發全部的NMP(沸點約2 0 3 °C )。重覆此 製程以製造箔表面每邊都黏附混合物之雙邊陰極。利 用隨後的真空乾燥以保証進一步地移除NMP。可利用 輪壓機或低壓滾輪進一步加強混合物對箔的附著力。 陽極之製造可利用將粒子尺寸1 〇微米、已於2 8 0 0 °C下加熱處理過之中間碳微珠（M C Μ B 1 0 2 8 )，與小量石 墨及做爲黏著劑之同聚合物PVdF1015混合而製得。 將此混合物從Ν Μ P溶液中使用類似於在陰極所描述的 方式澆鑄到銅箔上、乾燥及輪壓。 切割數片矩形的陽極薄片及陰極薄片，該些薄片將突 出金屬箔條。於一個特定的實例中陽極可爲3 1毫米X 48毫米5及陰極爲29毫米χ46毫米，每個電極在其一個 末端皆具有9毫米寬未塗佈的矩形接頭。 翅合電Ί 現在看至第1圖，其爲在電池製造期間的終端正視圖’ 然後矩形平板電池可從5 0毫米寬的多孔薄膜長條 1 0、九片雙邊陰極薄片1 2 ( 2 9毫米χ 4 6毫米）及十片陽 極薄片1 4 ( 3 1毫米X 4 8毫米）組合而成；其中該陽極薄 片有八片爲雙邊的、陽極薄片1 4a僅在其上表面具有 陽極混合物及陽薄片1 4 b僅在其下表面具有陽極混合 -7-
