Electroplating delivers high-energy, high-power batteries

[font size=3]CHAMPAIGN, Ill. — The process that makes gold-plated jewelry or chrome car accents is now making powerful lithium-ion batteries.
Researchers at the University of Illinois, Xerion Advanced Battery Corporation and Nanjing University in China developed a method for electroplating lithium-ion battery cathodes, yielding high-quality, high-performance battery materials that could also open the door to flexible and solid-state batteries.
…
The researchers demonstrated the technique on carbon foam, a lightweight, inexpensive material, making cathodes that were much thicker than conventional slurries. They also demonstrated it on foils and surfaces with different textures, shapes and flexibility.
“These designs are impossible to achieve by conventional processes,” Braun said. “But what’s really important is that it’s a high-performance material and that it’s nearly solid. By using a solid electrode rather than a porous one, you can store more energy in a given volume. At the end of the day, people want batteries to store a lot of energy.”
