Energy Storage Materials

Researchers at National Taiwan University have proposed a novel method to predict the onset of lithium metal formation—an internal battery response—during fast charging, using only external voltage measurements from commercial lithium-ion cells.

A recent study evaluating garnet-type solid electrolytes for lithium metal batteries finds that their expected energy density advantages may be overstated. The researchers posited that composite or quasi-solid-state electrolytes may be more viable alternatives.

Process that can lead to mass synthesis yields solid sulfide electrolyte with world’s highest reported sodium ion conductivity and glass electrolyte

- Research team led by Professor Hongkyung Lee at DGIST developed a manufacturing process for high-quality thin film lithium cathode based on electroplating that can replace commercial lithium foil - Expected to improve battery life and replace existing lithium foil due to simple size enlargement

- DGIST Department of Energy Science and Engineering Professor Lee Jong-won's team developed oxide-based solid electrolyte technology with enhanced atmospheric stability - Anticipating the development of high-performance/high-safety all-solid-state batteries...
