In battery cells, current collectors—which typically are made of copper—are essential for the transport of electrons. Although copper has excellent conductivity, it is expensive and heavy.

When batteries operate, ions move between two electrodes — the anode and the cathode — through the electrolyte. At the end of each electrode is a metal current collector, which conducts ...

The new braided current collector was just as stable as the continuous wire, but made it possible to increase the energy density by interacting with the graphite. As the team explain: “The ...

KIMS is a government-funded research institute under the Ministry of Science and ICT. A current collector acts as a crucial part of manufacturing a thin film electrode plate.
