Carbon-based materials for advanced lithium metal batteries based on carbon units of different dimensions

We discuss recent advances in the control and design of carbon hosts/carriers based on their dimensionality (0D, 1D, 2D and 3D) for achieving high performance Li metal anodes. Representative modification strategies for these different carbons for studying their lithium affinity and their influence on the anode performance are highlighted and discussed. Prospects for the design of carbon hosts/carriers for practical rechargeable LMBs are discussed.
