Sentences with phrase «performance electrode materials»

Not exact matches

In fact, there have been many efforts to improve lithium - ion battery or supercapacitor performance using alternative electrode materials such as carbon nanotubes and other manganese oxides.

Used as a counter electrode in a dye - sensitized solar cell, the material enabled the cell to convert power with up to 6.8 percent efficiency and more than doubled the performance of an identical cell that instead used an expensive platinum wire counter electrode.

Standard rechargeable batteries are only marginally suited for high performance: «To raise the energy density, you need to increase the voltage or the capacity, and that is where traditional electrode materials and electrolytic fluids reach their limits,» explains the physicist.

But the new analysis shows that the critical interface is actually between two solid materials: the electrode itself, and a carbon coating used to improve its performance.

Electrode - electrolyte interaction, structural stability and material performance will be characterized in various of battery and fuel cell systems.

But Duan said that the performance of the active material in such tiny amounts is canceled out by the bulkier inactive components of an electrode, like the current collectors.

Scientists in the consortium will be studying different materials that could be used for a lithium - metal battery's positive electrode, while working to prevent unwanted chemical reactions that could impair the battery's performance.

A number of nanoscale materials have been explored as potential electrode materials that could promise far higher performance than today's batteries.
