摘要:
An electrochemical cell such as a lead acid cell, wherein fine carbon particles with or without an organic material is disposed in the electrolyte of the cell, deposited on the surface of the electrically active material of the cell and/or dispersed within the electrically active material of the cell.
摘要:
A manganese dioxide-containing cathode comprising heat-treated manganese dioxide, a binder and a conductive agent and wherein the walls of the pores of the cathode are coated with a vapor deposited organic solvent thereby reducing its affinity for absorbing moisture when exposed to a moisture environment for a fixed time period. The invention also relates to a method for producing the organic solvent treated manganese dioxide-containing cathode.
摘要:
A process for prolonging the life of a lead-acid battery by adding an organic polymer and ultra fine lignin to its electrolyte and then discharging the battery at a high current rate and the battery so produced.
摘要:
The disclosure of this application is directed to silver catalyzed manganese dioxide which is useful as a hydrogen gas absorber. The silver catalyzed manganese dioxide of this invention can be formed into a shaped article of desired configuration, inserted into an electrochemical cell such as a battery, which is subsequently sealed, to absorb hydrogen gas evolved within the cell. Absorption of hydrogen gas by the silver catalyzed manganese dioxide prevents excessive build-up of gas pressure within the sealed cell thus minimizing the possibility of rupture and complete failure of the cell.
摘要:
A metal oxide alkaline cell, such as a silver oxide-zinc cell, having a negative electrode, an alkaline electrolyte, a positive electrode comprising for example divalent silver oxide housed in a positve terminal container, a separator disposed between the negative electrode and the positive electrode, and wherein a thin porous, electronically conductive layer, such as a gold layer, is disposed between the positive electrode and the separator and is extended to contact the positive terminal container.
