Polypyrrole hollow nanospheres: stable cathode materials for sodium-ion batteries.
Hollow polypyrrole (PPy) nanospheres with high sodium storage capacity as cathode materials for Na-ion batteries were reported. PPy hollow nanospheres demonstrated high current rate capacity and good cyclability. It was revealed by electrochemical testing and DFT calculation that the as-prepared PPy hollow nanospheres participate in reversible doping/de-doping reactions.
متن کاملDevelopment of an Ion Emitter with Hollow Cold Cathode
Ion physics forms the basis for numerous modern technologies and research directions such as microelectronics, material research, analytics or high-energy physics. The reason for the broad range applications of ion physics lies in the ions characteristics: -The ions possess a mass, which makes a direct energy transfer possible to the solid atoms (flexible energy transmission); -The velocity of ...
متن کاملSource Properties of a Hollow Cathode Arc Plasma
Experiments have been carried out on the properties of a hollow cathode as an ion-source. The measured electron density, ion and neutral temperatures and drift velocities have been compared with predictions from the conservation laws for matter, momentum and energy. Very large exit drift velocities of ions and neutrals are observed. The magnitude and direction, against the electric field, can b...
متن کاملHollow Cathode Discharges for Gas Lasers
With the exception of the 632.8 nm neon line all the important visible and ultraviolet cw gas laser lines belong to the spectra of ionized atoms. To achieve proper laser oscillation the excitation of the upper levels of these lines is of primary importance. High energy electrons are needed for this process. As such electrons are in high concentration in the hollow cathode discharge, it was obvi...
متن کاملLithium-Fed Hollow Cathode Theory
A theory for the single-channel hollow cathode (SCHC) that includes the relevant physical processes and predicts the operating parameters is presented. A SCHC consists of a cylindrical channel approximately ten diameters in length through which a working gas (taken as lithium vapor here) flows and exits as a plasma. A high current (1-100 A) is conducted into the channel by the plasma and to the...
