This paper disscussed some making technology of hyperoxide cathode
The properties ofcathode such as electron emisson
anti-blast ability
life time were tested.The resultsindicated that hyperoxide cathode have better qualities than oxide cathode in followingaspects:The volocity of activation is quick;There is no CO
2
gas was released duringdecomposition reaction;Good emission;Anti-blast ability;Long life-time etc
