Abstract
本發明係關於一種電池組模組,其包含空間上分開的電池組電池及接觸相鄰電池組電池的障壁材料之陣列。包含聚有機矽氧烷發泡體、阻燃劑、及中空陶瓷粒子之該障壁材料提供耐燃性及可壓縮性及熱絕緣。
Description
本發明係關於用經處理之聚有機矽氧烷發泡體障壁絕緣的電池組模組。
諸如鋰離子電池組(lithium-ion battery, LiB)之可充電電池組常用於包括電動車(electric vehicle, EV)及網格能量儲存系統之多種應用中。儘管LiB具有高能量密度及穩定性之理想特性,但安全性擔憂目前限制了其有用性。首先,LiB電池(cell)之故障可由於製造缺陷、內部短路、過熱、過量充電、或機械衝擊而觸發;其次,由發生故障的電池產生之熱可傳播,藉此導致鄰近電池中之熱失控。由此等熱事件產生之快速壓力堆積增加了著火及爆炸風險。
可藉由將提供熱絕緣及耐燃性的熱障壁置放於LiB模組中之電池之間而緩解熱失控。諸如氣凝膠、陶瓷纖維、及雲母板之常用熱障壁提供此類特性;然而,氣凝膠及陶瓷纖維缺點係機械彈性較差,而雲母板缺點係可壓縮性較差。另一方面,雖然聚矽氧吹塑發泡體提供充分可壓縮性,且因此適合於低能量密度及中等能量密度之電池組,但其缺點係熱絕緣不足以阻止極高能量密度電池組包之熱失控。因此,可充電電池組熱障壁領域中期望產生提供熱絕緣、耐燃性、及令人滿意的可壓縮性之障壁。
本發明藉由提供一種電池組模組解決所屬技術領域中之需求:該電池組模組包含的殼體,其含有空間上分開的電池組電池及接觸相鄰電池組電池的障壁材料之陣列,其中以該障壁材料的重量計,該障壁材料包含35至95重量百分比之聚有機矽氧烷發泡體;1至30重量百分比之阻燃劑;及1至15重量百分比之膨脹型珠岩;其中該障壁材料之密度在0.10至0.90 g/cm
3範圍內。
本發明之電池組模組為諸如鋰離子電池組等應用提供改良的熱及耐燃特性。
本發明係一種電池組模組,其包含殼體,該殼體含有空間上分開的電池組電池及接觸相鄰電池組電池的障壁材料之陣列,其中以該障壁材料的重量計,該障壁材料包含35至95重量百分比之聚有機矽氧烷發泡體;1至30重量百分比之阻燃劑;及1至15重量百分比之膨脹型珠岩;其中該障壁材料之密度在0.10至0.90 g/cm
3範圍內。
可藉由修改US 5,358,975中所描述之方法來製備障壁材料,其為熱絕緣、耐燃性、及可壓縮發泡體聚有機矽氧烷。舉例而言,經至少兩個且較佳至少三個Si-H基團官能化之聚二甲基矽氧烷(a)有利地與以下接觸:一或多種係水、醇、二醇、多元醇的含羥基化合物或含有至少一個矽醇基團之化合物(b)、二乙烯基官能化之聚二甲基矽氧烷(c)、諸如基於鉑之催化劑的矽氫化催化劑(d)、阻燃劑(e)、及膨脹型珠岩(f),以形成具有-Si-CH
2-CH
2-Si-基團及-Si-O-R基團之絕緣、可壓縮性、及耐燃性發泡體材料之交聯網狀結構,其中R係H或醇、二醇、多元醇、或矽醇之結構單元(亦即反應產物)。組分(a)、(b)、及(c)之總量在聚有機矽氧烷發泡體之35或40重量百分比至80或至70重量百分比之範圍內。
可能有利的係使用2部分方法製備障壁材料,其中在第一容器中,將二乙烯基官能化之聚二甲基矽氧烷之第一部分;阻燃劑之第一部分;矽氫化催化劑;一或多種含羥基化合物;及膨脹型珠岩之第一部分摻合,以形成部分A組成物。在第二容器中,將二乙烯基官能化之聚二甲基矽氧烷之剩餘部分;聚合物樹脂摻合物,其係二乙烯基官能化之聚二甲基矽氧烷與交聯有機聚矽氧烷樹脂之混合物;阻燃劑之剩餘部分;經至少三個Si-H基團官能化之聚二甲基矽氧烷;及膨脹型珠岩之剩餘部分摻合,以形成部分B組成物。隨後將部分A及B合併且混合,隨後傾倒於兩個離型膜片之間以形成本發明之發泡體材料。
阻燃劑係在加熱時釋放CO

熱絕緣及可燃性
使用設置於液壓機上之加熱板來測試如實例中所描述而製備之發泡體的熱絕緣及可燃性。將加熱板設定為600℃,其中絕緣體位於表面之頂部上。使用Kapton膠帶將四個熱電偶(K型)固定於鋁散熱片(4" × 4" × 0.47")上。隨後樣本(4" × 4")置放於且使用Kapton膠帶固定於散熱片上。使用Kapton膠帶將額外熱電偶(K型)附接至樣本表面。自熱表面移除絕緣體且將附接至散熱片之樣本快速置放於熱表面上,其中樣本表面面向加熱板表面且Al散熱片面向相對側。壓力快速增加至355 kPa。使用資料記錄器記錄加熱板表面與樣本表面之間的介面溫度及樣本表面與散熱片之間的介面溫度。一旦達至300 s之時間,釋放壓力,且結束測試。在樣本表面< 300℃之溫度視為可接受的。在整個測試中無可觀測的火焰視為可接受之耐燃性。
硬度
硬度使用蕭氏00硬度計量測。將測試樣品置於硬平坦表面上。隨後將蕭氏00硬度計之壓頭按壓至樣品上,確保其平行於表面。在與樣品牢固接觸期間讀取硬度。<80之硬度視為可接受的。
壓縮力
壓縮力使用配備有100 kg測力計、直徑係40 mm之鋁探針的TA.HDplus質構分析儀、及平坦重型鋁基材來量測。使用直徑係1"之模切將聚矽氧發泡體樣本切成圓形,且置放於基材與探針之間。探針最初設定為與樣本厚度相同之高度,且以1 mm/s之速率降低直至壓力達到最大。樣本厚度及壓力記錄為壓縮力曲線。記錄在原始樣本厚度之30%下的壓力。<500 kPa之壓縮力視為可接受的。
發泡體密度
發泡體密度係基於直徑係1吋之兩個發泡體樣本的平均厚度及重量計算。
