Charge injection creates oxidized and reduced forms of the organic semiconductor molecules near the anode and cathode, respectively, and the different optical properties of these species have been ...

Lithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their ...

Now, a new study shows The Dincă Group at Princeton has developed a high-energy sodium-ion cathode that shows promise to potentially outperform many lithium-ion counterparts. Their cathode ...

which occurs when batteries lose their ability to hold a charge over time. This degradation is primarily caused by chemical ...

This essentially clogs up the cathode, resulting in the lithium ions being unable to conduct a charge efficiently. They figured this out by replacing hydrogen atoms in a battery with deuterium ...

Recently, a research team achieved real-time tracking of electronic/magnetic structure evolution in Li-rich Mn-based ...

Instead, the cathode material is applied in a dry powder ... still use liquid electrolytes to shuttle electrons between charge and discharge cycles. But studies suggest it’s a step towards ...
