摘要:
A homogeneous mass of particulate manganese dioxide which has been heat-treated to reduce its moisture content and treated with an organic solvent which substantially fills the pores of the manganese dioxide thereby reducing its affinity for absorbing moisture when exposed to a moisture environment for a fixed time period. The invention also relates to a process for producing the manganese dioxide.
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:
Coherent manganese dioxide electrodes comprising particulate manganese dioxide and particulate electrically conductive material substantially uniformly dispersed in a conductive binder wherein said binder comprises colloidal electrically conductive material having a surface area as defined by the B.E.T. method using N.sub.2 absorption at 78.degree.K of less than about 100m.sup.2 /g, and an electrolyte-wettable polymeric binder.
摘要:
A timed-release acid dissoluble organic polymer pellet for use as an additive in an acid electrolyte of a lead-acid battery to prolong the life of the battery and a process of using the organic polymer pellet in a lead-acid battery.
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:
