Copper Dissolution in Overdischarged Lithium-ion Cells: X-ray Photoelectron Spectroscopy and X-ray Absorption Fine Structure Analysis

, 2020
In some applications, such as military or back-up energy applications, lithium-ion batteries can undergo storage for multiple years without use. If the batteries are not properly maintained, the pack voltage can decrease over time due to cell self ...

Structural and electronic investigation of ZnO nanostructures synthesized under different environments

Heliyon, 2018
An explicit study of comparison on the basis of structure and electronic properties of ZnO nanostructures was discussed. ZnO synthesized by sol-gel and hydrothermal method without using any surfactant leads to the formation of two different morphologies.
