Stabilizing Li-Rich Layered Cathode Materials Using a LiCoMnO₄ Spinel Nanolayer for Li-Ion Batteries

Nanomaterials, 2022
Lithium–rich cathodes have excess lithium in the transition metal layer and exhibit an extremely high specific capacity and good energy density. However, they still have some disadvantages. Here, we propose LiCoMnO4, a new nanolayer coating material with

Measurement of the rate capability of Resistive Plate Chambers [PDF]

Journal of Instrumentation, 2009
This paper reports on detailed measurements of the performance of Resistive Plate Chambers in a proton beam with variable intensity. Short term effects, such as dead time, are studied using consecutive events. On larger time scales, for various beam intensities the chamber.s efficiency is studied as a function of time within a spill of particles.
