Description

Researchers have developed a new technique to solve the problem of how to increase the capacity of sodium-ion batteries.

The research in Applied Physics Reviews was jointly led by Professor Oleg Kolosov from Lancaster University and Professor Zhigao Huang from Fujian Normal University, with key results obtained by Associate Professor Yue Chen from both Lancaster and Fuzhou.

Professor Kolosov said, “Nanoscale studies of rechargeable storage are essential for the development of new, efficient and safe batteries.

“This study will enable a cheaper and safer energy storage alternative to lithium-ion batteries, with lithium being much scarcer and more difficult to mine compared with sodium batteries. This fundamental research is expected to ultimately enhance the cycle stability, lifespan, and capacity of batteries.”
