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 - ...

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 ...

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. ...

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 ...

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 ...

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 ...

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 ...

Combined heat and power on a residential scale, also known as micro-cogeneration, is currently gaining traction as an energy savings practice. The configuration of micro-cogeneration systems is highly variable, as local ...
