Illinois University, Xerion Advanced Battery Corporation and Nanjing University Developed a Method for Directly Electroplating Lithium-Ion Battery Cathodes

The University of Illinois at Urbana-Champaign, Illinois battery technology developer Xerion Advanced Battery Corp. and Nanjing University in China joined their expertise to find an innovative cathode material manufacturing technique to push the boundaries of the performance capability of lithium-ion batteries.

The researchers found that their electroplating method, which was formerly known in the production of gold-plated decoration of car details, can replace the glue-like binders normally used to build battery cathodes. The conventional paste limited the storing capacity and affected the free energy flow within the battery. The new electroplated cathode increases the battery power by 30 percent and additionally stabilizes the material. Huigang Zhang, Professor at Nanjing University sees great potential for the finding: “This method opens the door to flexible and three-dimensional battery cathodes, since electroplating involves dipping the substrate in a liquid bath to coat it.”
