Using molten-salts as a thermal processing medium for cobalt-free lithium-rich cathode material
Lithium-rich nickel manganese oxide cathode materials are well known to have limited rate capabilities. In this investigation we demonstrate that modifying a common sol-gel synthetic route by adding simple salts to the precursors during firing can create a molten-salt environment for the synthesis of the material that may results in improved materials and performance attributes. After screening multiple salt species, our findings indicate that the use of NaCl can provide a cost-effective and facile method for increasing the rate capability of these materials.
期刊介绍:
Electrochemistry Communications is an open access journal providing fast dissemination of short communications, full communications and mini reviews covering the whole field of electrochemistry which merit urgent publication. Short communications are limited to a maximum of 20,000 characters (including spaces) while full communications and mini reviews are limited to 25,000 characters (including spaces). Supplementary information is permitted for full communications and mini reviews but not for short communications. We aim to be the fastest journal in electrochemistry for these types of papers.
