Abstract

Abstract: Invited for this month's cover picture is the work of Dr. Kataoka, Dr. Taguchi, Dr. Tada and Dr. Takeichi at AIST and Dr. Machida at QST. The cover picture shows that the charge‐discharge cycle characteristics have been improved by reducing the particles size of the layered compound Na2/3 Mn2/3 Ni1/3 O2 to the several nm level.

However, the researchers found that the cycling performance of Na2/3Mn2/3Ni1/3O2 with P2‐type layered oxide significantly improved by lowering its crystallinity without a decrease in the reversible capacity and average potential by ball milling…" Learn more about the story behind the research featured on the front cover in this issue's Cover Profile.
