Lithium-metal anodes are the most promising electrodes for next-generation high-energy-density batteries. In their Communication on page 7764 ff., Q. Zhang and co-workers employed a nitrogen-doped graphene matrix (lotus leaves) with lithiophilic nucleation sites (sitting frogs) to guide Li (tadpoles) nucleation on an anode surface. The result is a uniform distribution of Li on the anode surface. These dendrite-free lithium-metal anodes exhibit an impressive electrochemical performance.
