Recently, a consensus has been reached that using lithium metal as an anode in Li-ion batteries is the best way to obtain the high energy density necessary to power electronic devices. Challenges remain, however, with respect to controlling dendritic Li growth on these electrodes, forming a stable solid–electrolyte interface layer. Herein, we suggest a groundbreaking solution to these challenges consisting in the preparation of a organic/inorganic layer that can be used to cover Li electrodes via a simple fabrication method. Not only does this protecting layer impede direct contact between electrode and electrolyte, thus avoiding side reactions, but it assists and expedites Li-ion flux in batteries, thus suppressing Li dendrite growth. Notably, protective layer-incorporating Li cells comprising high capacity/voltage cathodes with reasonably high mass loading showed highly stable cycling performance in a carbonate-based electrolyte. |
