Quantum Batteries VS Lithium-ion battery

Nguyen Quang Hung, Nguyen Tuan Loi and Tran Dong Xuan

Researcher and leturer

This report compares lithium-ion batteries with emerging quantum batteries, highlighting differences in operating principles and potential applications. While lithium-ion batteries base on electrochemical ion transfer and are widely used in modern electronics, quantum batteries exploit quantum phenomena such as tunneling, entanglement, and superposition for ultrafast charging and long-term energy retention. We introduce models using FGMOS transistors, outline the structural design and theoretical advantages of quantum batteries. Recent advancements—including room-temperature demonstrations and photon-assisted charging—are updated. Although still in early development, quantum batteries show strong promise for future use in high-efficiency energy storage systems. Keywords: Quantum battery, lithium-ion, Electron tunneling.
