dc.description.abstract | The practical implementation of the lithium metal anode is hindered by obstacles such as Li dendrite growth, large volume changes, and poor lifespan. Here, copper nitride nanowires (Cu3N NWs) printed Li by a facile and low-cost roll-press method is reported, to operate in carbonate electrolytes for high-voltage cathode materials. Through one-step roll pressing, Cu3N NWs can be conformally printed onto the Li metal surface, and form a Li3N@Cu NWs layer on the Li metal. The Li3N@Cu NWs layer can assist homogeneous Li-ion flux with the 3D channel structure, as well as the high Li-ion conductivity of the Li3N. With those beneficial effects, the Li3N@Cu NWs layer can guide Li to deposit into a dense and planar structure without Li-dendrite growth. Li metal with Li3N@Cu NWs protection layer exhibits outstanding cycling performances even at a high current density of 5.0 mA cm(-2) with low overpotentials in Li symmetric cells. Furthermore, the stable cyclability and improved rate capability can be realized in a full cell using LiCoO2 over 300 cycles. When decoupling the irreversible reactions of the cathode using Li4Ti5O12, stable cycling performance over 1000 cycles can be achieved at a practical current density of approximate to 2 mA cm(-2). | en_US |
