Electrodes for Li‐Ion Batteries

2015
The electrochemical energy storage is a means to conserve electrical energy in chemical form. This form of storage benefits from the fact that these two energies share the same vector, the electron. This advantage allows us to limit the losses related to the conversion of energy from one form to another.

Li-ion batteries: Phase transition

Chinese Physics B, 2016
Progress in the research on phase transitions during Li+ extraction/insertion processes in typical battery materials is summarized as examples to illustrate the significance of understanding phase transition phenomena in Li-ion batteries. Physical phenomena such as phase transitions (and resultant phase diagrams) are often observed in Li-ion battery ...

Li-Ion Battery Charging Efficiency

ECS Transactions, 2016
The main objective of this article is determination of the charging and discharging efficiency of the Li-ion battery depending on the value of the charging and discharging current. An automated workplace allows us to measure the capacity of cells, temperature and other parameters required for assessing the performance of batteries.

Combining a proton exchange membrane fuel cell (PEMFC) stack with a Li-ion battery to supply the power needs of a hybrid electric vehicle

Renewable Energy, 2019
A fuel cell hybrid electric vehicle (FCHEV) is more advantageous compared to a gasoline-powered internal combustion engine based vehicle or a traditional hybrid electric vehicle (HEV) because of using only one electric motor instead of an internal ...
