The number of newly registered electric vehicles (EVs) in Korea surpassed 100,000 units last year alone. Norway is the only other country to match such numbers. The core materials that determine the battery life and charging speed of now commonly seen EVs are anode materials. Korea's domestic battery industry has been committed to finding revolutionary ways to increase the battery capacity by introducing new technologies or other anode materials. But what if we get rid of anode materials altogether?
A POSTECH research team led by Professor Soojin Park and PhD candidate Sungjin Cho (Department of Chemistry) in collaboration with Professor Dong-Hwa Seo and Dr. Dong Yeon Kim (School of Energy and Chemical Engineering) at Ulsan Institute of Science and Technology (UNIST) have developed anode-free lithium batteries with performance of long battery life on a single charge.
The newly developed anode-free battery has a volumetric energy density of 977Wh/L which is 40% higher than the conventional batteries (700wh/L). This means that the battery can run for 630km on a single charge.
