      abstract     = {Anode-free Li-metal batteries are of significant interest
                      to energy storage industries due to their intrinsically high
                      energy. However, the accumulative Li dendrites and dead Li
                      continuously consume active Li during cycling. That results
                      in a short lifetime and low Coulombic efficiency of
                      anode-free Li-metal batteries. Introducing effective
                      electrolyte additives can improve the Li deposition
                      homogeneity and solid electrolyte interphase (SEI) stability
                      for anode-free Li-metal batteries. Herein, we reveal that
                      introducing dual additives, composed of LiAsF6 and
                      fluoroethylene carbonate, into a low-cost commercial
                      carbonate electrolyte will boost the cycle life and average
                      Coulombic efficiency of NMC||Cu anode-free Li-metal
                      batteries. The NMC||Cu anode-free Li-metal batteries with
                      the dual additives exhibit a capacity retention of about
                      $75\%$ after 50 cycles, much higher than those with bare
                      electrolytes $(35\%).$ The average Coulombic efficiency of
                      the NMC||Cu anode-free Li-metal batteries with additives can
                      maintain $98.3\%$ over 100 cycles. In contrast, the average
                      Coulombic efficiency without additives rapidly decline to
                      $97\%$ after only 50 cycles. In situ Raman measurements
                      reveal that the prepared dual additives facilitate denser
                      and smoother Li morphology during Li deposition. The dual
                      additives significantly suppress the Li dendrite growth,
                      enabling stable SEI formation on anode and cathode surfaces.
                      Our results provide a broad view of developing low-cost and
                      high-effective functional electrolytes for high-energy and
                      long-life anode-free Li-metal batteries.},
