High current electron beam generation in a vacuum transient hollow cathode discharge
(1993)
Experimental observations are presented of prebreakdown electron beam generation in a transient hollow cathode discharge (THCD) in a vacuum. The discharge driver consists of a 400-kV maximum voltage, 25-nF Marx operated ...
Electrochemical performance of Mo doped high voltage spinel cathode material for lithium-ion battery
(Elsevier, 2018-02)
This article deals with the properties of high-voltage cathode material LiNi0.5Mn1.5O4 synthesized by a solid-state reaction method and the influence of doping this material by molybdenum. The samples – LiMox+ yNi0.5 - ...
Study of the influence of the scandium doping to the properties of high voltage LiNi0.5Mn1.5O4 cathode
(Electrochemical Society, 2015-10)
One of the problems which were always associated with accumulators in general is their low voltage. For powering a more demanding application, there is always the need to stack more cells together to obtain a higher voltage. ...
Comparative Study of the Properties of High Voltage Spinel Cathode Material Depending on the Method of Synthesis
(Electrochemical Society, 2014-10)
The most widely used cathode materials for lithium-ion accumulators nowadays are based on LiCoO2, LiFePO4 or LiMnO4. These materials are supposed to be replaced by battery systems with new generation of cathode materials ...
LiMn1.8Ni0.2O4 nanorods obtained from a novel route using α-MnOOH precursor as cathode material for lithium-ion batteries
(Elsevier Science, 2018-07)
Nanorod structures of LiMn1.8Ni0.2O4 applicable as active cathode material for Li-ion batteries were synthesized from α-MnOOH and α-MnO2 initial phases. The LiMn1.8Ni0.2O4 spinel nanorods obtained from α-MnOOH using a ...
Metallic cathode surface modification by using low pressure pulsed vacuum arc discharge
(Universidad Nacional de Colombia Sede Medellín, 2012)
Electrical discharges in a pulsed vacuum arc system at low pressure were produced using a peak current of 100A with pulses of 30 ms. Discharges were carried out applying a voltage of 104 V between the electrodes. Materials ...
Electron beam measurements in a pulsed capillary discharge
(IEEE, 1998)
In this work we present experimental observations of the XUV and electron beam emission properties of an ultrafast pulsed capillary discharge, which combines the features of a transient hollow cathode discharge with the ...
Electrochemical performance of Na0.6[Li0.2Ni0.2Mn0.6]O2 cathodes with high-working average voltage for Na-ion batteries
(Royal Society of Chemistry, 2017-12)
Na0.6[Li0.2Ni0.2Mn0.6]O2 is synthesized by a self-combustion reaction (SCR) and studied for the first time as a cathode material for Na-ion batteries. The Na0.6[Li0.2Ni0.2Mn0.6]O2 cathode presents remarkable high rate ...
Using a TV Set to Show Electron Diffraction
(2013-07-05)
We show the feasibility of constructing a simple set-up to demonstrate the diffraction of electrons starting from a standard TV set. Two concentric rings around a central maxima appears on the screen of the modified TV set ...
Studies on pulsed hollow cathode capillary discharges
(IET, 1996)
We present preliminary results on radiation characteristics of pulsed hollow cathode capillary discharges. The device combines the on axis electron beam assisted ionization capabilities of the transient hollow cathode ...
