Appl. No.:

6/290607

Inventors:

Joseph R. Driscoll - Sunnyvale CA

Assignee:

Altus Corporation - San Jose CA

International Classification:

H01M 436

US Classification:

429101

Abstract:

An electrochemical cell having improved efficiency and life is provided wherein substantially the total volume of the liquid cathode is contained within the pores of a solid, porous, nonconsummable current collector and separator, said current collector having a first constituent consisting of an electrically conducting material which is less electropositive than the anode, and a second constituent consisting of an electrically nonconductive material, said first and second constituents being combined such that the resistivity of said current collector varies inversely with the distance from said anode.
