ベースのゲルである。シリカは、沈殿、ヒューム、コロイドおよび/または化学修飾されたものを含む任意のシリカであり得る。別の実施形態において、ゲル化剤は、ケイ酸塩および/または非ケイ酸塩鉱物または化合物または高吸収ポリマーであり得る。
以下の表は、ゲル化剤を用いた不織布とゲル化剤を用いない不織布との間の比較を示す。用いた不織布は、40wt%の溶解性繊維(セルロース)および60wt%の非溶解性繊維(ポリエステル)を有するGlatfelterのDYNAGRID328NGペーストペーパー(基本重量28gsm)とした。
不織布を2週間後にセル中に配置。5枚のシートを試験し、平均抵抗を報告した。
上した電池セパレータ、コンポーネント、電池、および/または関連する製造方法および/または使用方法と、鉛酸電池中において用いられるゲル含浸不織布を用いた電池セパレータと、ゲル含浸不織布と、および/またはこのようなセパレータまたは不織布を含む電池の必要性に対処するか、これらをを提供するか、またはこれらに向けられる。
