摘要:

A method is described whereby the life of an oxide cathode can be substantially increased when subjected to repeated air exposures. This is accomplished by preventing the hydrate formation, and consequently reducing flaking of the cathode coating. Further limitations to cathode life caused by the effects of poisoning are also discussed.
