Hollow cathode chemical modelling
, 2008 In this paper the state of hollow cathode life time modelling at the University of Southampton will be reported. Two models have been developed: one for BaO depletion from the hollow cathode insert and another for low work function compounds deposition ...

High Power LiMn2O4 Hollow Microsphere Cathode Materials for Lithium Ion Batteries
International Journal of Electrochemical Science, 2013 Lithium manganese oxide (LiMn2O4) hollow microspheres have been synthesized by using MnCO3 precursor as a self-template. The microstructure of the hollow microspheres is characterized by X-ray diffraction and environmental scanning electron microscopy ...

Note: Coaxial-heater hollow cathode
Review of Scientific Instruments, 2017 The design and tests of a LaB6 hollow cathode with a novel heater are presented. In the new design, the heater wire is completely encapsulated around the cathode tube and a coaxial return electrode, thereby eliminating hot spots on the heater wire due to the free hanging regions. Since the new heater confines the Joule heating to the region of interest,

Advanced Materials, EarlyView.Aqueous ammonium‐ion batteries (AAIBs) face a hydrogen‐bond paradox: the HB network enables fast NH4+ transport but triggers water decomposition. This review dissects this dilemma, evaluates multiple electrolyte engineering strategies, and outlines four future directions for next‐generation AAIB design ABSTRACT Aqueous ammonium‐ion batteries (AAIBs ...

Advanced Materials Interfaces, EarlyView.This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
