| Abstract Scope |
The heavy reliance of lithium-ion batteries (LIBs) has caused rising concerns on the sustainability of lithium and transition metal (TM) and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio. The alternative technologies play a vital role in shaping the future landscape of energy storage, from electrified mobility to the efficient utilization of renewable energies and further to large-scale stationary energy storage. Potassium-based batteries (PIBs) are a promising alternative given its chemical and economic benefits, making a strong competitor to LIBs and sodium ion batteries (SIBs) for different applications. The presentation will discuss the advantages of potassium-based batteries, particularly the K-O2 battery, as well as the challenges associated with their development. Furthermore, our recent progress in potassium superionic conductors will be discussed, which will be crucial in solving challenges in potassium batteries. |
