A Highly Reversible Lithium Metal Anode by Constructing Lithiophilic Bi‐Nanosheets

) cathode (Negative/Positive ratio: 2.91). Even in anode-free metal lithium batteries, NBF has higher capacity during cycling compared with NF. To conclude, NBF shows excellent electrochemical performance and provides an idea of facile preparation method which can be extend to other metal batteries.
