Abstract

Description
本出願は、2015年9月2日に出願された米国特許出願第62/213,470号の利益およびこれに対する優先権を主張する。この仮出願は参照により本明細書に援用される。
該当なし
7つのテストサンプルが用意された。この7つのテストサンプルの全てが、中国のリヤオヤンにあるDalian Thrive Metallurgy Import & Export Co., LTDから入手可能な、連続したニッケル発泡体基板に用意された。このニッケル発泡体基板は、1インチあたり10の細孔を有する99.5%多孔性であり、厚さ1.6mm、幅200mmである。一般的には、これらのサンプルは長いロール(一般的には1ロールあたり167m)に準備され、所望の長さにカットできる。
基板としてのアルミニウムと銅の発泡体の材料が、今回試験された。その目的は、ニッケル発泡体と対応する、アルミニウムと銅の発泡体の密度と多孔性を複製することである。ニッケル発泡体は、0.92グラム/ccであった。我々が入手したアルミニウムと銅の発泡体のサンプルは、0.14および0.2グラム/ccである。これらは相当に少ないが、銅発泡体によって放電中により高い電圧を示す。これらのテストは継続中である。同等の効果を示すアルミニウムと銅の発泡体を得るための試みが始まっている。
