Latest Patents

Suh's latest patents include the "Quinone and Hydroquinone Based Flow Battery" and the "Small Organic Molecule Based Flow Battery." The first invention provides an electrochemical cell that utilizes a new chemistry for flow batteries designed for large-scale electrical energy storage. In this system, electrical energy is stored chemically in quinone molecules that possess multiple oxidation states. During the charging process, quinone molecules at one electrode are oxidized, releasing electrons and protons, while the molecules at the other electrode are reduced by accepting these electrons and protons. This process is reversed to deliver electrical energy. Additionally, the invention introduces various high and low potential quinones that are beneficial for rechargeable batteries.

The second patent, the "Small Organic Molecule Based Flow Battery," also focuses on large-scale energy storage. In this design, electrical energy is stored chemically at an electrochemical electrode through the protonation of small organic molecules known as quinones to hydroquinones. The proton is supplied by a complementary electrochemical reaction occurring at the other electrode. Similar to the first invention, these reactions can be reversed to provide electrical energy, and this flow battery architecture offers scaling advantages over traditional solid electrode batteries.
