Observation of the hollow cathode effect from a dielectric cathode

open access: yes, 2010
The hollow cathode effect (HCE) is investigated in the dielectric hollow cathode structure in a Ne–Xe mixture at 4%. The influence of the dielectric is shown experimentally by the relationship between voltage and current peaks.

Fabrication of Composite Cathode for All‐Solid‐State Sodium Batteries

open access: yesAdvanced Energy Materials, EarlyView.
The design of composite cathodes for all‐solid‐state sodium batteries must address three critical challenges—interfacial side reactions, interfacial delamination, and highly tortuous transport pathways. This work outlines structural and interfacial strategies to optimize ion transport and mechanical stability, enabling durable, and high‐performance ...

Hollow cathode apparatus

open access: yes, 1984
A hollow cathode apparatus is described, which can be rapidly and reliably started. An ignitor positioned upstream from the hollow cathode, generates a puff of plasma that flows with the primary gas to be ionized through the cathode.
