The implementation of a robust artificial solid electrolyte interphase(ASEI)to replace the unstable natural SEI can regulate lithium deposition behaviors and avoid the safety hazards caused by dendrites permeation in lithium metal *** of devoted efforts in tailoring components of ASEI,the intrinsic mechanism of interfacial synergy within the heterogeneous interphases has not been well elucidated ***,we show that the lithium plating/striping behaviors can be substantially enhanced(over 900 h with an overpotential of less than 20 mV at 1 mA·cm^(−2)in Li|Li symmetric cells and 146 cycles in anode-free cells)by regulating the heterogeneous *** favorable ASEI composed of LiF and Li_(3)N components can be in-situ generated during cycling by large-scale fabricated fluorinated boron nitride ***,the synergy of each heterogeneous component within ASEI was explored theoretically and ***_(3)N has high adsorption energy and low ion diffusion barrier,which facilitates the transport of lithium ions and avoids its local accumulation to evolve into *** the substrate and LiF are interfacially stable with high electron tunneling barriers,preventing the electrolyte decomposition and parasitic ***,the high stiffness of the boron nitride also ensures lithium dendrites are suppressed once they grow,providing a stable environment for long-term cycling of lithium metal batteries.

Conventional charging methods for lithium-ion battery(LIB)are challenged with vital problems at low temperatures:risk of lithium(Li)plating and low charging *** study proposes a fast-charging strategy without Li plating to achieve high-rate charging at low temperatures with bidirectional *** strategy combines the pulsed-heating method and the optimal charging method via precise control of the battery states.A thermo-electric coupled model is developed based on the pseudo-twodimensional(P2D)electrochemical model to derive charging *** current maps of pulsed heating and charging are generated to realize real-time ***,our proposed strategy achieves a 3 C equivalent rate at 0℃ and 1.5 C at-10℃ without Li plating,which is 10–30 times faster than the traditional *** entropy method is employed to balance the charging speed and the energy efficiency,and the charging performance is further *** practical application,the power limitation of the charger is considered,and a 2.4 C equivalent rate is achieved at 0℃ with a 250 kW maximum power *** novel strategy significantly expands LIB usage boundary,and increases charging speed and battery safety.
