Batteries: The Role of AlF3 Coatings in Improving Electrochemical Cycling of Li-Enriched Nickel-Manganese Oxide Electrodes for Li-Ion Batteries (Adv. Mater. 9/2012)
Y.-K. Sun, C. S. Yoon, B. Scrosati and co-workers report on page 1192 the role of an AlF3-coating layer on Li-enriched cathode materials, which not only improves electrochemical performances but also thermal stability. These improvements are attributed to the trans-formation of the initial layer (Li2MnO3) to a spinel phase, induced by the Li chemical-leaching effect of the AlF3 coating layer. The spinel phase transferred from the layer on the Li-enriched electrodes is able to negate the previous shortcomings of these designs.
