What is it about?
Rechargeable batteries are increasingly in demand for larger devices such as electric vehicles that require high performance. The reaction at the interface between electrode and electrolyte strongly influences a battery’s performance.

Why is it important?
To better understand this reaction, a team of Japanese scientists used frequency-modulation atomic force microscopy (FM-AFM) in liquid to observe the structure of the interface with high resolution. In particular, they looked at the interface structure between tetraglyme and graphite — the electrode material and organic solvent, respectively, in lithium-ion batteries. The results were published in The Journal of Chemical Physics.
Perspectives
Ultimately, understanding the interface between the electrode and electrolyte could lead to enhancements for better performance in rechargeable batteries. In the future, Minato and his colleagues hope to observe the interface structure between electrode and electrolyte in a working rechargeable battery.
