Can “oiling” the electrodes of automotive fuel cells prevent their degradation? Unlike their larger, utility-scale counterparts that run continuously, automotive fuel cells are frequently turned off and on, allowing electrodes to corrode during the off state due to unwanted chemical reactions. The introduction of a specialized catalyst is shown to contain the problem. A research team […]
The word battery simply means a group of similar components. In military vocabulary, a “battery” refers to a cluster of guns. In electricity, a “battery” is a set of voltaic cells designed to provide greater voltage and/or current than is possible with one cell alone. The symbol for a cell is very simple, consisting of one long […]
Battery testing system in Dr. Yu’s Lab for developing advanced electrode materials. Credit: The University of Texas at Austin For years, researchers have aimed to learn more about a group of metal oxides that show promise as key materials for the next generation of lithium-ion batteries because of their mysterious ability to store significantly […]
Coulombic Efficiency: Research Gate We seldom stress about buying a new phone every few years. We want the new technology. Hence with phones, lithium-ion battery aging is hardly an issue. It is, however, a major factor with an electric vehicle. Those lithium batteries can cost as much as a small fossil-fueled car pumping out pollution. Concept Electric Car: NREL: […]
Nickel metal hydride battery (Commonly abbreviated to “Nimh battery”) has dominated the market today. This is because the battery chemistry is advanced in performance, safety, the cycle of life, and other parameters. In addition to that, manufacturers are working to improve the cell. The cell is designed to be used on electronic products that consider run time. […]
Power failures do occur at times in our places of residents, businesses, and workplaces. This power failure can last for an extended period. And as we know, without electricity, all our work or pleasure will stop. Therefore, there is the need to have backup systems so that our work is protected from damage or data […]
Nickel metal hydride (NiMH) batteries are an improvement from nickel-cadmium (NiCd) batteries, especially as they replace cadmium (Cd) with a metal that can absorb hydrogen.
NiMH can provide higher capacity than NiCd batteries, have less obvious memory effect, and be more environmentally friendly without the toxic cadmium.
For most renewable energy systems, as like solar street light, the most important battery characteristics are the battery lifetime, the depth of discharge and the maintenance requirements of the battery. Some solar street lights produced with Lead/VRLA/AGM batteries by default. However, the total cost of ownership (TCO) of these types of batteries is much higher than […]
